What Are the Product Testing Standards of GRC Manufacturers? Introduction to Qinglong GRC's Testing Standard System

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

Qinglong's adopted standard system comprises three levels: national standards, industry standards, and enterprise standards. Its product testing strictly follows industry standards such as the "Technical Standard for Application of Glass Fiber Reinforced Cement in Building" (JGJ/T423-2018), and exceeds 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%.

Raw Material Testing Standards

Strict raw material acceptance standards have been established, and all raw materials must pass testing before entering storage.

In-Process Inspection Standards

Multiple inspection points are set up during production to ensure every process step is qualified.

Finished Product Inspection Standards

Finished products are subject to a 100% inspection system and may only leave the factory once all indicators meet requirements.

Through strict implementation of standards, product quality is ensured to be stable and reliable.
