What Are the Product Testing Standards of GRC Manufacturers? An In-Depth Analysis of Qinglong GRC Manufacturer's Testing Standard System

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

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 the Technical Standard for Application of Glass Fibre Reinforced Cement in Buildings (JGJ/T423-2018), and it exceeds standard requirements on many 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 high standard requirements ensure excellent product performance.

Raw Material Testing Standards

Strict raw material acceptance standards are established, and all raw materials must pass inspection before entering the warehouse. Key materials such as cement, sand, and fibre have clear technical indicator requirements, ensuring quality is controlled at the source.

In-Process Inspection Standards

Multiple inspection points are set up during production to ensure every process step is qualified. From batching and mixing to molding and curing, each stage has detailed inspection standards and records.

Finished Product Inspection Standards

A full inspection system is applied to finished products, and only products meeting all indicators may leave the factory. Key indicators such as flexural strength, water absorption, and appearance quality must be 100% compliant.

Through strict standard implementation, Qinglong ensures its product quality is stable and reliable. Customers are advised to learn in detail about the manufacturer's testing standards and quality control system when making purchases.
