Product testing standards are the foundation of GRC quality assurance. Qinglong, a GRC manufacturer, strictly implements national and industry standards and has established more stringent internal control standards to ensure leading product quality.

The standard system adopted by Qinglong comprises three levels: national standards, industry standards, and enterprise standards. Its product testing strictly follows industry standards such as JC/T940 "Glass Fibre Reinforced Cement Decorative Products" and exceeds standard requirements on multiple indicators. For example, the standard requires flexural strength of ≥18MPa, while Qinglong's internal control standard requires ≥20MPa; the standard requires water absorption below 10%, while Qinglong keeps it under 6%. Such stringent standard requirements ensure product performance above industry levels. The company's laboratory is CNAS accredited, and its testing data carries international credibility.

National Standard System

Follows national standards such as GB/T 14684 "Sand for Construction". These standards are the basic requirements for product quality that all products must meet.

Enterprise Internal Control Standards

Internal control standards stricter than national standards have been established, with raised requirements on key indicators such as strength and durability to ensure superior product performance.

Testing Method Standards

Testing is conducted according to standard methods. Strength tests use the three-point bending method, and durability tests are carried out over standard cycles, ensuring accurate and reliable test results.

Strict implementation of standards ensures stable and reliable product quality. Choose manufacturers that implement high standards to obtain premium products.
