Our Current Certifications

  • EN71-3

    Heavy metal safety standard

    European standard testing PVC materials for heavy metal migration (lead, cadmium, chromium). Ensures safe material composition for workers and end-users.

    Note: EN71-3 is a material safety standard, not a fire rating.

  • SGS Tested

    Third-party verification

    Independent testing by SGS (world’s leading inspection company) covering material composition, tensile strength, tear resistance, chemical safety and batch consistency.

  • Japan Fire Retardant

    Fire safety certification

    Verifies PVC material meets fire retardant standards — critical for welding enclosures, paint booths and facilities near flammable materials.

  • DIN 4102 B1

    Flame retardant (schwer entflammbar)

    German fire protection classification for materials that are difficult to ignite and self-extinguish when the ignition source is removed. Required for industrial curtains in facilities with strict fire safety codes across Europe.

  • DIN 4102 B2

    Normal flammability (normal entflammbar)

    Standard fire classification for PVC materials that do not significantly contribute to fire spread. Suitable for warehouse dividers, wash bay curtains and general industrial partitioning.

Quality Assurance Process

  • Tensile testing machine with its terminal on the lab bench

    1. Raw material inspection

    Every batch of PVC resin and additives undergoes incoming inspection. We verify supplier certifications and test material properties before manufacturing.

  • Dial thickness gauge measuring a sample of orange PVC mesh

    2. In-house testing lab

    Our Jiangxi facility measures thickness, tensile strength, tear resistance, colour consistency and dimension accuracy.

  • Flammability test cabinet and its control unit in the SKP lab

    3. Finished product testing

    Before shipment, panels are sampled and tested to verify specs match the order. Full documentation and batch traceability are included.

US Market — NFPA 701 & ASTM E84

SKP Material is actively pursuing NFPA 701 and ASTM E84 fire retardant certifications for the US market. We currently have fire-retardant PVC formulations with test reports available upon request.

Request Certification Documents

Facility managers, engineers and procurement professionals can request at no cost: EN71-3 test reports, SGS certificates, DIN 4102 B1/B2 fire classification reports, fire retardant documentation, MSDS sheets, and batch-specific quality reports.
