An isolated defect is the easiest to resolve but the easiest to under-document. Count the affected panels, record their positions in the pack, and photograph the batch label in the same frame. A systemic defect needs more than a replacement promise: ask what changed in the batch \u2014 the binder, the pigment lot, the mold, the line \u2014 and what will be different in the replacement. A specification dispute is not a quality failure until the reference is agreed; if the purchase order is silent, the approved sample and the product data sheet become the reference.<\/p>\n
Which measurements should I take on flexible stone panels?<\/h2>\n
Measure the properties that the product actually declares, and measure enough panels to see whether the problem is local or spread across the batch.<\/p>\n
- \n
- Thickness.<\/strong> Use a caliper at three points on each sampled panel. Flexible stone veneer is declared in a 2\u20138 mm band depending on the pattern; thin styles such as travertine sit around 2.5\u20133 mm, while heavier patterns reach 8 mm. Compare the readings with the band for the pattern, not with a generic range.<\/li>\n
- Weight per square metre.<\/strong> Weigh a representative sample and convert to kg\/m\u00b2. The declared range is 1.5\u20136 kg\/m\u00b2 depending on the design. A batch that drifts to the top of its band may be denser; a batch below the band may have a thinner binder layer.<\/li>\n
- Dimensions.<\/strong> Check the sheet size against the ordered format. The standard is 1200 \u00d7 600 mm, with larger formats up to 1200 \u00d7 2900 mm.<\/li>\n
- Bend behaviour.<\/strong> Flex a corner over a cylinder and inspect for cracks or delamination. The general minimum radius is about 200 mm; thick or complex patterns such as Starmoon are around 300 mm, and thin styles can go tighter.<\/li>\n
- Backing.<\/strong> Look at the back edge for fiberglass mesh coverage and separation between layers. A panel with exposed mesh at the edge or a lifting backing is a defect even if the face looks perfect.<\/li>\n
- Color and relief.<\/strong> Compare the batch with the retained first-article sample under daylight, at normal viewing distance and close up. If the visual comparison is borderline, ask for a measured color difference (\u0394E) from the factory or an independent lab.<\/li>\n<\/ul>\n

<\/p>\nSampling is a statistical decision, not a guess. Agree the sample size and the acceptance rule in the purchase order before production. The NIST\/SEMATECH handbook on acceptance sampling<\/a> explains the logic of sampling plans; you do not need to invent an AQL number on the inspection day. If the contract has no sampling clause, inspect enough panels to support the decision you are about to make, and record the sample size.<\/p>\n
What documents should I pull before contacting the supplier?<\/h2>\n
Put the reference documents in one folder before you send the notice. The supplier will ask for them, and the third-party inspector may need them to interpret the findings.<\/p>\n
- \n
- The purchase order and any technical annex, including the thickness and weight band, pattern code, backing, and packaging requirements.<\/li>\n
- The approved first-article sample record, with the signed sample identifier and photographs.<\/li>\n
- The batch-specific COA, plus the test reports for the product and thickness supplied.<\/li>\n
- The packing list, the pallet or crate labels, and the batch number that ties the shipment to the production record.<\/li>\n
- The inspection report, the raw measurements, and the photographs.<\/li>\n
- The product data sheet and the installation manual, in case the dispute is about a declared property or a substrate requirement.<\/li>\n<\/ul>\n
If the purchase order does not define acceptance criteria, say so explicitly in the notice. The fallback reference is the approved sample and the declared product data, not the inspector\u2019s personal preference. The batch consistency check<\/a> shows how the same documents are used on a reorder, and the manufacturer-versus-trading-company guide<\/a> explains what to verify before the first order.<\/p>\n
What remedies can I ask for?<\/h2>\n
The remedy should match the classification and should be written down with dates. A practical sequence is:<\/p>\n
- \n
- Sort and replace.<\/strong> For isolated defects, require the supplier to remove the affected panels, replace them from conforming stock, and provide photographs of the sorted pack before loading.<\/li>\n
- Rework or replace the batch.<\/strong> For systemic defects, require a new production run or a documented rework, with the root cause identified and the corrected batch re-inspected before shipment.<\/li>\n
- Re-inspect.<\/strong> Make the re-inspection a condition of loading, not a promise after arrival. The cost of re-inspection can be agreed in the purchase order; if it is not, negotiate it before the second inspection.<\/li>\n
- Delay the shipment.<\/strong> A short delay is usually cheaper than a container of material that has to be replaced at the destination.<\/li>\n
- Cancel the affected lot.<\/strong> Reserve cancellation for a systemic failure that the supplier cannot correct in time. It is the last resort, not the opening move.<\/li>\n<\/ul>\n
Who pays for the remedy depends on the contract and the Incoterm. Our standard term is FOB Shanghai; under FOB, risk passes when the goods are on board, so a defect caught before loading is a supplier conversation, while a defect found after discharge is usually an insurance or claim conversation. That is why the inspection happens before the container is closed.<\/p>\n
Do not accept a verbal promise to \u201cfix it in the next batch.\u201d Ask for a corrective action plan with a responsible person, a date, and the evidence that will be provided. Do not let the affected panels be mixed with conforming stock; a mixed container makes the claim harder and the installation risk higher.<\/p>\n
How do I prevent the same failure on the next batch?<\/h2>\n
Prevention starts in the purchase order. Lock the thickness and weight band for the pattern, the backing construction, the pattern or color code, the packaging spec, and the inspection rights. If the order is a reorder, reference the approved sample and the batch number that was accepted. The \u0623\u062f\u0644\u0629 \u0627\u0644\u0645\u0634\u062a\u0631\u064a<\/a> cover the sourcing side of this in more detail.<\/p>\n
Keep the first-article sample and the inspection report with the order file. Use the same measurement sheet on every batch so the numbers are comparable; a report that changes format every time cannot show a trend. Ask for the batch number on the COA, the packing list, and the pallet label, and check that the three agree before the container is loaded.<\/p>\n
If the same defect appears twice, treat it as a process problem rather than a shipment problem. The factory\u2019s corrective action should address the cause \u2014 the binder mix, the pigment lot, the mold condition, the packing line \u2014 not only the panels in front of you. A factory that can explain what changed is easier to trust than one that promises the next batch will be better.<\/p>\n
What should the final inspection report contain?<\/h2>\n
A useful report is short enough to read and specific enough to act on. It should include:<\/p>\n
- \n
- Header: purchase order number, product and pattern, batch number, inspection date, inspector, quantity inspected, and sample size.<\/li>\n
- Findings by category, with counts and photographs, separated into isolated, systemic, and specification issues.<\/li>\n
- A measurement table with the declared band, the measured values, and the pass or fail result for each property.<\/li>\n
- A conclusion: pass, fail, or conditional pass with the conditions listed.<\/li>\n

- Rework or replace the batch.<\/strong> For systemic defects, require a new production run or a documented rework, with the root cause identified and the corrected batch re-inspected before shipment.<\/li>\n
- Sort and replace.<\/strong> For isolated defects, require the supplier to remove the affected panels, replace them from conforming stock, and provide photographs of the sorted pack before loading.<\/li>\n
- Weight per square metre.<\/strong> Weigh a representative sample and convert to kg\/m\u00b2. The declared range is 1.5\u20136 kg\/m\u00b2 depending on the design. A batch that drifts to the top of its band may be denser; a batch below the band may have a thinner binder layer.<\/li>\n
