Quality documents for your purchasing review

Use the document reference and sample specification when requesting evidence for your project. Management-system certification, sample test results and patents serve different purposes. Open each section to review references and scope.

01 · Company certificates and facility documentation

Quality management system

The supplied certificate identifies our quality management system against GB/T 19001-2016 / ISO 9001:2015.

Certificate: 33923Q14368R0S
Scope: production of tarpaulin and knife-scraping cloth
Issuer: ZQHX Certification Center Co., Ltd.
Issued: 18 December 2023
Printed expiry: 17 December 2026

The certificate requires successful periodic surveillance. Request current verification for procurement. This is a management-system certificate, not a fire or waterproof rating for every product.

High-tech enterprise recognition

The company certificate records Chinese High-tech Enterprise recognition, number GR202543000201, issued on 8 December 2025 with a stated validity of three years.

This is company-level recognition. Material suitability still depends on the specification and relevant test evidence.

Facility documentation

The supplied pollutant discharge permit identifies the company and manufacturing premises.

Permit: 91430922MABNFQ4653001U
Printed period: 10 July 2023 to 9 July 2028
Issuing authority: Yiyang Municipal Ecology and Environment Bureau

This facility permit is separate from product testing and does not establish an environmental claim for a finished product.

02 · Submitted-sample test results — four reports

Four reports from Zhejiang ZTT Testing Co., Ltd. (ZTT), completed on 8 January 2025, identify submitted knife-scraping cloth samples. Each report covers one sample.

Grey

Report: W2025-00209

Measured mass per unit area: 717 g/m²
Tensile load, warp / weft: 2758 / 2336 N/5 cm

Blue — sample B

Report: W2025-00216

Measured mass per unit area: 584 g/m²
Tensile load, warp / weft: 2589 / 2674 N/5 cm
Tear load, warp / weft: 330 / 250 N

Methods recorded: tensile load — GB/T 1040.3-2006; tear load — HG/T 2581.1-2022, method C; mass per unit area — GB/T 4669-2008, method 5. The peel test under GB/T 8808-1988 (5 cm specimen width) records “unable to peel throughout” for both directions; no numerical peel-load value is reported.

These are measured results for the identified samples, not guaranteed specifications for all colours, batches or products. The two blue reports concern different samples. The reports do not specify a product model or material composition. Ask us to match the report to your proposed material and agree order specifications and tolerances. These reports do not provide fire, UV-weathering, food-contact or hydrostatic-waterproof ratings.
