What Are the Product Testing Standards of GRC Manufacturers? Analysis of Core National and Industry Standards

The testing standards for GRC products are the legal basis for measuring product quality and the core guideline for manufacturers' production. Understanding GRC product testing standards helps customers judge whether products are compliant, and also reflects the manufacturer's professionalism. Currently, GRC product testing mainly follows two levels of standards: national and industry standards. Qinglong Group, as a manufacturer that participated in standard formulation, explains the core testing standards and key indicators for you.

#Basic Standard: Glass Fiber Reinforced Cement (GRC) Decorative Products (JC/T940-2022)

This is the core basic standard for GRC decorative products, which specifies key contents such as product classification, technical requirements, test methods, and inspection rules. In terms of technical requirements, it stipulates core indicators for GRC products including appearance quality (no obvious cracks, bubbles, or other defects), dimensional deviation (length and width deviation ≤ ±3mm), physical and mechanical properties (compressive strength ≥ 40MPa, flexural strength ≥ 8MPa), and durability (strength loss rate after freeze-thaw cycles ≤ 15%). The test methods section details the testing procedures for indicators such as strength, durability, and impermeability, ensuring the accuracy and impartiality of test results. Qinglong, as a unit with outstanding contributions to the revision of this standard, strictly follows it throughout the entire production process.

#Application Standard: Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018)

This standard focuses on the building application of GRC products, clarifying the technical requirements for GRC components in design, construction, acceptance, and other stages. In terms of design, it stipulates requirements such as load calculation, fire protection design, and seismic design for GRC components; in construction, it specifies norms for installation techniques, anchoring methods, and joint treatment; in acceptance, it establishes indicators such as appearance quality, dimensional deviation, and installation precision. Qinglong participated deeply in the formulation of this standard and strictly follows it throughout the entire process of GRC building applications, ensuring project compliance and safety.

#Specialized Performance Testing Standards: Focusing on Specific Needs

For different application scenarios, GRC products also have specialized testing standards. For example, GRC products used for exterior walls must comply with the Standard for Quality Acceptance of Decoration Engineering of Building Exterior Walls (GB/T50210), with attention to indicators such as wind pressure resistance, water tightness, and air tightness; products used in fire protection scenarios must comply with the Classification of Burning Behavior of Building Materials and Products (GB8624) to ensure the fire rating meets requirements; overseas projects must comply with relevant standards of the international GRC association or the technical specifications of the project's host country. Qinglong's GRC products can meet various specialized testing standards according to different scenario requirements, adapting to diverse project needs.

The product testing standards of GRC manufacturers are the core guarantee of product quality. Compliant manufacturers strictly follow national and industry standards to ensure all product indicators meet requirements. Qinglong Group, as a participating unit in standard formulation, not only strictly implements existing standards but also promotes standard upgrades through technological innovation, keeping product quality at the industry's leading level. Only by choosing a GRC manufacturer that follows core testing standards can you ensure products are compliant and qualified, providing fundamental assurance for project safety and quality.
