| 1 | Product construction and declared specifications | Product technical data sheet; documented quality-control specification | Panel material, core composition, surface finish, nominal length and width, thickness, density or mass per unit area, edge profile, and permitted tolerances. | Confirm that the tested product has the same composition, thickness, surface treatment, backing, and installation method as the product being quoted. | High |
| 2 | Fire performance | EN 13501-1 for European reaction-to-fire classification; ASTM E84 for surface-burning characteristics in North America | Independent laboratory report showing flame-spread and smoke results, test configuration, panel thickness, substrate, adhesive, and mounting method. | Use the classification required by the destination building code. Do not treat an ASTM E84 result as automatically equivalent to an EN 13501-1 classification. | High |
| 3 | Formaldehyde and indoor-air emissions | EN 717-1 for formaldehyde emission from wood-based panels; ASTM E1333 for large-chamber emissions testing; ISO 16000 series for indoor-air measurements | Laboratory report identifying the tested panel, adhesive, conditioning conditions, chamber method, measured concentration, and reporting units. | Compare results with the legal or green-building requirements of the importing market. Confirm whether the test covers the complete panel assembly rather than only one raw material. | High |
| 4 | Moisture resistance and water absorption | ASTM D570 for water absorption of plastics; product-specific moisture or immersion methods may also apply | Water-absorption percentage, immersion duration, specimen dimensions, preconditioning, post-test swelling, edge-sealing details, and visual inspection results. | For bathrooms, kitchens, basements, or humid climates, verify both face and edge performance. A water-resistant surface does not necessarily mean the entire panel is waterproof. | High |
| 5 | Dimensional stability and thermal movement | EN 438-2 includes dimensional-stability methods for high-pressure decorative laminates; other materials require a relevant product-specific method | Length and width change after heat or humidity exposure, test temperature and duration, initial dimensions, final dimensions, and stated installation expansion gap. | Check that the laboratory specimen matches the intended climate and installation system. Allow movement at joints where the manufacturer’s instructions require it. | High |
| 6 | Surface wear, scratch, stain, and impact resistance | EN 438-2 provides relevant methods for decorative laminate abrasion, scratch, stain, and impact performance | Wear cycles or rating, scratch load, stain agents, impact energy or drop height, test temperature, and photographs of tested surfaces before and after testing. | Match the test severity to the application: residential, hospitality, healthcare, retail, or high-traffic commercial use. Ask for separate results for printed, embossed, or matte finishes. | Medium |
| 7 | Acoustic performance | ISO 354 for sound absorption in a reverberation room; ASTM C423 for sound absorption and sound absorption coefficients | Noise Reduction Coefficient (NRC) or sound absorption coefficients by frequency, mounting arrangement, air gap, backing material, and complete assembly description. | Do not compare acoustic values from different mounting systems without adjustment. A decorative panel alone may perform differently from a panel installed with an acoustic backing and air cavity. | Medium |
| 8 | Color consistency and light stability | Documented color-control procedure; relevant lightfastness or color-change method selected for the panel material and end use | Color measurement method, reference sample, acceptable color difference, batch identification, exposure conditions, gloss level, and approved master sample. | Require a physical control sample before mass production. Check panels from different production lots because shade and gloss can vary even when the nominal color code is unchanged. | Medium |
| 9 | Factory quality management and traceability | ISO 9001 certification, where applicable; certificate scope should cover the relevant manufacturing activity | Current certificate, certification scope, issuing certification body, validity dates, lot or batch coding, inspection records, nonconformity process, and retained-sample policy. | ISO 9001 certifies a quality-management system, not automatic compliance of every panel. Verify that the certificate is current and that product traceability reaches raw materials and finished goods. | High |
| 10 | Pre-shipment inspection, packaging, and installation readiness | ISO 2859-1 can be used for attribute-based sampling plans; installation instructions should be product-specific | Inspection level, acceptance quality limit, quantity inspected, dimensional results, appearance defects, carton labeling, pallet protection, moisture protection, spare percentage, and installation accessories. | Approve a written inspection plan before production. Confirm that packaging protects corners and surfaces during international transport and that labels identify lot, quantity, orientation, and handling requirements. | High |
