ما هي معايير اختبار المنتجات لدى مصنعي GRC؟ تعريف بمنظومة معايير الاختبار

Product testing standards are the foundation of GRC quality assurance. Qinglong, as a GRC manufacturer, strictly implements national and industry standards and has established even stricter 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/T 940 "Glass Fibre Reinforced Cement Decorative Products" and is stricter than standard requirements on multiple indicators. For example, while the standard requires flexural strength ≥18MPa, Qinglong's internal control standard requires ≥20MPa; while the standard requires water absorption <10%, Qinglong controls it at <6%. Such strict standard requirements ensure that product performance exceeds industry levels. The company's laboratory is CNAS accredited, and its test data carries international credibility.

National Standard System

Compliance with national standards such as GB/T 14684 "Sand for Construction". These standards are the basic requirements for product quality and must be met by all products.

Industry Standard Requirements

Strict implementation of industry standards such as JC/T 940 "Glass Fibre Reinforced Cement Decorative Products". These standards are formulated for the characteristics of GRC products, with more specific requirements.

Enterprise Internal Control Standards

Internal control standards stricter than national standards have been established. Requirements are raised 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 at standard intervals. This ensures accurate and reliable test results.

Strict standard implementation ensures stable and reliable product quality. Choose a manufacturer that implements high standards to obtain high-quality products.
