What Are the Product Testing Standards of GRC Manufacturers? An Analysis of the Qinglong GRC Testing Standard System

GRC product testing must follow national industry standards and enterprise internal control standards. Qinglong GRC strictly implements industry standards such as "Glass Fiber Reinforced Cement Decorative Products" JC/T940, and has established enterprise internal control standards that are stricter than national standards.

In terms of implementing testing standards, Qinglong has established a complete standards system. Appearance quality follows the GB/T38252-2019 standard, dimensional accuracy is controlled according to GB/T11969, mechanical properties are tested in accordance with JC/T940, and durability is verified with reference to JGJ144. In the Shenzhen Pingshan High-tech Zone project, all product testing indicators exceeded standard requirements; for example, the standard requires flexural strength ≥18MPa, while the actual value reached 23MPa, exceeding the standard by 27%.

Basic Requirements of National Standards

JC/T940 specifies basic mechanical performance indicators; GB/T38252 defines appearance quality requirements; JGJ144 provides durability testing methods. These standards are the quality baseline.

Higher Requirements of Enterprise Standards

Qinglong's internal control standards are stricter than national standards, with dimensional accuracy requirements increased by 30% and strength indicators raised by 20%. Such strict requirements ensure leading product quality.

Scientific Testing Methods

Standardized testing equipment and methods are adopted to ensure data comparability. The laboratory is CNAS accredited, making testing results authoritative and reliable.

Rational Testing Frequency

Batch testing of raw materials, sampling inspection during production, and 100% inspection of finished products. This frequency arrangement ensures quality is under control.

Testing standards must be strictly implemented. Choosing manufacturers that value standard implementation provides greater assurance of product quality. Qinglong GRC strictly adheres to standards, and customers are welcome to supervise.
