Desk work tests certificate scope, material links, QC reporting and prior findings. The floor tests line control, tooling, inspection, calibration, packing and traceability. Separate process evidence, product testing, system certification and product certification. DESO&#8217;s own pages describe manufacturing and inspection, but they are not independent audits; verify the exact order&#8217;s scope and records.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Does_a_Factory_Audit_Start_at_the_Desk\"><\/span>Why Does a Factory Audit Start at the Desk?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A PPR pipe factory audit starts at the desk because documents are cheap to review. Gaps in certificate scope, material records or reporting lines show up before you travel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use them to form questions, then let the floor confirm or contradict the answers. Leave with a scored sheet and a trace you watched, not brochures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Which_Four_Documents_Should_You_Review_Before_You_Visit\"><\/span>Which Four Documents Should You Review Before You Visit?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5.webp\" alt=\"Three-step PPR factory audit checklist graphic with Observe, Sample and Close cards connected by arrows, labeled buyer checks.\" class=\"wp-image-9487\" srcset=\"https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5.webp 1200w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-500x281.webp 500w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-300x169.webp 300w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-768x432.webp 768w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-18x10.webp 18w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-133x75.webp 133w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-480x270.webp 480w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-2-5-800x450.webp 800w\" sizes=\"auto, (max-width:767px) 480px, (max-width:1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Certificates_What_Do_They_Actually_Cover\"><\/span>1. Certificates: What Do They Actually Cover?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask for the certificate, its schedule or annex, and the issuer&#8217;s register entry. Check the holder, number, standard, product models, issue date and expiry date. Confirm the scope. A system certificate shows that a body assessed a management system against a standard, within a scope. It does not certify a pipe model. A product certificate may cover one model or one range, not every size you buy. For a PPR pipe factory, ask which certificate covers the exact product, pressure class and market. Verify it with the issuer, then compare the claim with the <a href=\"https:\/\/www.desopipe.com\/kk\/product-category\/ppr-pipe\/\" rel=\"noopener noreferrer\" target=\"_blank\">PPR pipe product scope<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Raw_Materials_Can_You_See_the_Chain_From_Resin_to_Batch\"><\/span>2. Raw Materials: Can You See the Chain From Resin to Batch?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Request the resin supplier list for the last six months, then pick one example lot. The record should show the resin grade, supplier lot, receipt date and the batch made from it. Follow it forward to the production date, line and finished-goods lot. This chain shows whether a PPR pipe factory controls material consistency or merely promises it. Ask how the factory prevents a grade mix-up. If the record names only &#8220;PPR&#8221; and a date, you cannot test the claim. Ask for measured values and the material lot behind them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Who_Does_Quality_Report_To\"><\/span>3. Who Does Quality Report To?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Get the organisation chart and a written answer naming who quality reports to. If quality reports to production, output targets can overrule a hold. That is a structural risk, even with capable staff. Ask who can stop a shipment, sign a deviation and inform the buyer. How a PPR pipe factory handles a non-conformance after you leave shows up in that reporting line. Confirm it with a recent hold record: reason, owner, correction and release signature. A chart alone shows intent; a hold record shows control.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_What_Did_the_Last_Two_Audits_Find\"><\/span>4. What Did the Last Two Audits Find?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask for the last two external audit reports, with findings and corrective actions. Read the non-conformities, not the cover page. Check each action for an owner, due date and evidence of closure. Compare them with the current organisation chart and batch records. Improvement after an audit only counts when it shows up in a PPR pipe factory&#8217;s daily work. Ask what changed and who verified it. If a report is unavailable, request a redacted summary. Refusing to discuss history is a finding.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Which_Four_Kinds_of_Evidence_Are_Buyers_Always_Confusing\"><\/span>Which Four Kinds of Evidence Are Buyers Always Confusing?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Buyers often say &#8220;they are certified&#8221; when they mean one of four things. Keep them separate. A PPR pipe factory may have strong evidence in one and none in another.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Evidence type<\/th><th>What it shows<\/th><th>What to request<\/th><\/tr><\/thead><tbody><tr><td>Process evidence<\/td><td>A controlled production step was recorded.<\/td><td>Batch card, line record or parameter sheet.<\/td><\/tr><tr><td>Product testing<\/td><td>A sample met a stated requirement.<\/td><td>Report with sample, method, standard, values, equipment and result.<\/td><\/tr><tr><td>System certification<\/td><td>A management system was assessed within a scope.<\/td><td>Certificate with holder, number, standard, validity and site, checked with the issuer.<\/td><\/tr><tr><td>Product certification<\/td><td>A product model was assessed against a product standard within a scope.<\/td><td>Certificate or listing with model, standard, scope and market.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Process evidence does not prove product performance. Testing does not prove system control. A system certificate does not certify a product. A product certificate may not cover your size or market. Ask for the scope and record for your order.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Also check holder, site and dates. A test report must identify the sample, method and measured values. None replaces the others.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Which_Six_Checks_Need_the_Factory_Floor\"><\/span>Which Six Checks Need the Factory Floor?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5.webp\" alt=\"Teal and light blue three-step flowchart titled PPR Factory Audit Checklist, showing Plan audit, Walk process and Review evidence in sequence.\" class=\"wp-image-9488\" srcset=\"https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5.webp 1200w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-500x281.webp 500w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-300x169.webp 300w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-768x432.webp 768w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-18x10.webp 18w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-133x75.webp 133w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-480x270.webp 480w, https:\/\/www.desopipe.com\/wp-content\/uploads\/2026\/11\/inside-1-5-800x450.webp 800w\" sizes=\"auto, (max-width:767px) 480px, (max-width:1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_How_Many_Lines_Are_Running_and_What_Is_Checked_at_the_Line\"><\/span>5. How Many Lines Are Running, and What Is Checked at the Line?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask how many extrusion lines are installed and how many run today. A line count is not capability. Read the line record for the product you plan to buy. It should show the date, shift, line, material lot, key settings and checks. Line-side checks at a PPR pipe factory catch drift before it becomes a finished bad lot. Ask who records the check and how often. Watch one check happen. The <a href=\"https:\/\/www.desopipe.com\/kk\/manufacturing\/\" rel=\"noopener noreferrer\" target=\"_blank\">manufacturing overview<\/a> may describe the flow, but the line record must match your order. Ask who approves a setting change and where it is logged.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Who_Controls_the_Tooling\"><\/span>6. Who Controls the Tooling?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask who designs, makes, repairs and approves the tooling. For fittings, the answer determines how fast a dimension problem can be fixed. Request the full tooling list, maintenance log and change record. If work is outsourced, ask who approves the drawing and checks the first part. A PPR pipe factory that cannot explain tooling control will struggle to hold fitting dimensions across lots. Walk to the tool store and match the label to the record. Ask how often the tool is checked. Compare the size with the <a href=\"https:\/\/www.desopipe.com\/kk\/product-category\/ppr-fitting\/\" rel=\"noopener noreferrer\" target=\"_blank\">PPR \u0444\u0438\u0442\u0438\u043d\u0433\u0456\u0441\u0456\u043d\u0456\u04a3 \u0430\u0441\u0441\u043e\u0440\u0442\u0438\u043c\u0435\u043d\u0442\u0456<\/a>. A tool that cannot be identified cannot be controlled.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Is_Inspection_In-Process_or_Only_Pre-Shipment\"><\/span>7. Is Inspection In-Process or Only Pre-Shipment?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask what is measured during production and what is checked only before shipment. Pre-shipment inspection usually happens when most goods are complete. It catches finished defects but cannot stop a whole lot from being made wrong. Look for in-process records: dimensions, appearance, weight and other agreed checks at defined intervals. Ask how a failed line check at a PPR pipe factory triggers a hold, rework or scrap. Follow one hold to its release. Ask to see the last three holds and causes. Record the result. A factory with only final inspection finds the loss after it happens.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"8_Is_the_Lab_Calibrated_and_Which_Tests_Are_Routine\"><\/span>8. Is the Lab Calibrated, and Which Tests Are Routine?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Visit the lab and ask which tests are routine, which are type tests and which are sent out. Ask for calibration records for the equipment used on your product. The lab at a PPR pipe factory may run dimensional, appearance or pressure-related checks. Confirm the method, sample and acceptance rule for each. Calibration should show the equipment identity, date, result and next due date. A sticker is not enough. If a test cannot be repeated on a known sample, treat the result as a claim. Ask how a failed test is handled and who authorises a retest. Record the result and owner.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"9_Does_the_Packing_and_Marking_Survive_the_Container\"><\/span>9. Does the Packing and Marking Survive the Container?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask for the packing specification, not a photo of a good-looking pallet. Check the label, length marking, bundle or carton, quantity, gross weight and shipping marks. Review the container loading plan. The pack has to protect the pipe through handling, stacking and transit. The packing spec should be linked to the order and inspection record at the PPR pipe factory. Ask how the pack is checked before loading and who signs it off. For custom labels or buyer documents, use the <a href=\"https:\/\/www.desopipe.com\/kk\/oem\/\" rel=\"noopener noreferrer\" target=\"_blank\">OEM documentation process<\/a> and verify the approval sample. A packing photo without a spec proves only that one pack existed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"10_Can_They_Trace_One_Carton_in_Front_of_You\"><\/span>10. Can They Trace One Carton in Front of You?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Place one sealed carton or bundle on the table. Ask the PPR pipe factory to trace it back to the resin lot and forward to the inspection record. Time it and note the result. The record should identify the product, size, batch, production date, line, sample, method and measured values. Match the carton label to the report and the shipping document. The <a href=\"https:\/\/www.desopipe.com\/kk\/quality-inspection\/\" rel=\"noopener noreferrer\" target=\"_blank\">inspection and batch record<\/a> page is DESO&#8217;s own description, not an audit; only a live rehearsal proves it for your order. If the trace needs a day and several people, the system is not ready for a claim.<\/p>\n\n\n\n<!DOCTYPE html>\n<html lang=\"en\">\n<head>\n  \n  <title>\u0411\u0430\u0442\u044b\u0440 \u04e9\u043d\u0456\u043c\u0456\u043d\u0456\u04a3 \u0435\u0440\u0435\u043a\u0448\u0435\u043b\u0456\u0433\u0456<\/title>\n  <style>\n    .hero-card {\n      display: flex;\n      flex-wrap: wrap;\n      align-items: center;\n      background: #f7f8fa;\n      border-radius: 16px;\n      box-shadow: 0 6px 20px rgba(0, 0, 0, 0.05);\n      padding: 24px;\n      max-width: 900px;\n      margin: 40px auto;\n      font-family: Arial, sans-serif;\n      text-decoration: none;\n      color: inherit;\n font-family: 'Poppins';\n    }\n\n    .hero-image {\n      width: 220px;\n      height: auto;\n      border-radius: 12px;\n      object-fit: cover;\n      flex-shrink: 0;\n    }\n\n    .hero-content {\n      padding-left: 24px;\n      flex: 1;\n      min-width: 260px;\n    }\n\n    .hero-title {\n      font-size: 1.6rem;\n      font-weight: bold;\n      margin-bottom: 12px;\n      color: #222;\n      font-family: 'Poppins',\n    }\n\n    .hero-description {\n      font-size: 1rem;\n      color: #555;\n      margin-bottom: 18px;\n    }\n\n    .hero-link {\n      display: inline-block;\n      padding: 10px 20px;\n      background-color: #0066cc;\n      color: #fff;\n      text-decoration: none;\n      border-radius: 8px;\n      font-weight: bold;\n      transition: background 0.2s ease-in-out;\n    }\n\n    .hero-link:hover {\n      background-color: #004c99;\n    }\n\n    @media (max-width: 640px) {\n      .hero-card {\n        flex-direction: column;\n        text-align: center;\n      }\n\n      .hero-content {\n        padding-left: 0;\n        padding-top: 20px;\n      }\n\n      .hero-image {\n        width: 100%;\n        max-width: 280px;\n      }\n    }\n  <\/style>\n<\/head>\n<body>\n\n<a class=\"hero-card\" href=\"https:\/\/www.desopipe.com\/kk\/product\/standard-ppr-pipe\/\" target=\"_blank\">\n  <img decoding=\"async\" class=\"hero-image\" src=\"https:\/\/www.desopipe.com\/wp-content\/uploads\/2025\/01\/4.webp\" alt=\"\u041a\u0430\u0439\u0432\u0438\u043d \u0442\u04af\u0441\u0442\u0456 \u049b\u0430\u043b\u0430\u043c\">\n  <div class=\"hero-content\">\n    <div class=\"hero-title\">\u0421\u0442\u0430\u043d\u0434\u0430\u0440\u0442\u0442\u044b PPR \u049b\u04b1\u0431\u044b\u0440\u044b<\/div>\n    <div class=\"hero-description\">\u0421\u0442\u0430\u043d\u0434\u0430\u0440\u0442\u0442\u044b PPR \u049b\u04b1\u0431\u044b\u0440\u044b \u0442\u04b1\u0440\u0493\u044b\u043d \u04af\u0439, \u043a\u043e\u043c\u043c\u0435\u0440\u0446\u0438\u044f\u043b\u044b\u049b \u0436\u04d9\u043d\u0435 \u04e9\u043d\u0435\u0440\u043a\u04d9\u0441\u0456\u043f\u0442\u0456\u043a \u049b\u04b1\u0431\u044b\u0440 \u0436\u04af\u0439\u0435\u043b\u0435\u0440\u0456\u043d\u0435 \u0441\u0435\u043d\u0456\u043c\u0434\u0456 \u0448\u0435\u0448\u0456\u043c \u04b1\u0441\u044b\u043d\u0430\u0434\u044b.<\/div>\n    <span class=\"hero-link\">\u04e8\u043d\u0456\u043c\u0434\u0456 \u043a\u04e9\u0440\u0443<\/span>\n  <\/div>\n<\/a>\n\n<\/body>\n<\/html>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Do_You_Score_the_Audit\"><\/span>How Do You Score the Audit?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Score each check. 2 means evidence matches. 1 means a claim only. 0 means evidence contradicts.

It does not certify a product model or every size. Ask for a product certificate where your market requires it. Confirm the model and standard, verify the record with the issuer and request product testing for your order.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Can_You_Audit_a_Factory_Remotely\"><\/span>Can You Audit a Factory Remotely?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, partly. Run the four desk checks remotely and request live video. Review records, labels and packing specs. A remote PPR pipe factory audit cannot confirm every line condition, tool state or handling practice. Use a third party for the floor and mark unseen items unverified.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Long_Should_an_Audit_Take\"><\/span>How Long Should an Audit Take?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A focused audit needs one desk day and one floor day, plus sample testing and follow-up. The traceability rehearsal should take minutes, not a day. If one record takes a day to find, record that as a finding. The schedule depends on product range, site access and records requested.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_the_Next_Step\"><\/span>\u041a\u0435\u043b\u0435\u0441\u0456 \u049b\u0430\u0434\u0430\u043c \u049b\u0430\u043d\u0434\u0430\u0439?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Use the ten checks. Clear the desk stage first, then let the floor confirm or contradict the file. Score answers, keep zeros visible and stop at a critical gap. A capable PPR pipe factory can show the scope and measured result. Review the <a href=\"https:\/\/www.desopipe.com\/kk\/about-us\/\" rel=\"noopener noreferrer\" target=\"_blank\">DESO company background<\/a>, then verify scope and records for your order.
