How to Verify the Authenticity of Test Data Provided by Manufacturers?

During the procurement of UHPC/GRC/GRG/GRP materials, testing data is the core basis for measuring product quality. However, some manufacturers on the market engage in data falsification, report tampering, and other issues, making the scientific verification of testing data authenticity an important topic for designers, owners, and engineering parties. With 28 years of industry experience, Qinglong Group draws on its full-chain service practice to provide you with a systematic verification solution.

### 1. Verify the Completeness of Basic Information in the Testing Report First, confirm whether the report has legal validity. A legitimate UHPC/GRC/GRG/GRP testing report should include the CMA (China Metrology Certification) or CNAS (Laboratory Accreditation) mark, and the report number can be verified on the official website of the issuing authority. Taking Qinglong Group as an example, all product testing is completed by authoritative institutions such as the National Building Materials Testing Center, and the report information strictly corresponds to the enterprise's production standards. Meanwhile, check whether the material model and production batch in the report match the actual supplied products to avoid mismatches.

### 2. Cross-Verify Authenticity Through Technical Parameters The core performance indicators of different materials have industry-recognized ranges, and the reasonableness of data can be judged through the logical relationships between parameters. For example, the flexural strength of GRC materials is typically 15-25MPa; if a report shows above 30MPa, be alert to data anomalies. The standard value of UHPC compressive strength must be no less than 120MPa, and accompanying indicators such as elastic modulus and chloride ion penetration coefficient must also meet standards simultaneously. As a participating unit in developing the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," Qinglong fully understands the correlations between parameters. We recommend that customers compare the manufacturer's testing report against industry standard requirements, and where necessary, request supporting raw material testing evidence.

### 3. Conduct On-Site Inspection of Production and Testing Capabilities The most direct way to verify data authenticity is to inspect the manufacturer's production strength and testing system. Qinglong Group's production base in Nanning, Guangxi is equipped with advanced laboratories capable of monitoring key processes such as material proportioning and strength testing in real time, and customers can witness the sampling and testing process on site. In addition, check whether the manufacturer has established a complete quality traceability system. For example, the raw material QR code traceability technology adopted by Qinglong can clearly trace the testing records of each batch of products, ensuring data credibility from the source.

### 4. Reference Project Cases and Industry Reputation Long-term stable engineering applications are strong proof of the authenticity of testing data. Projects Qinglong participated in, such as the translucent concrete project at Century Plaza on Nanjing East Road and the GRC exterior wall project of the Dongguan Women and Children's Activity Center, have all verified material performance through third-party testing and actual use. We recommend that customers consult project parties in the same industry to learn about the actual performance of the target manufacturer's products, or check corporate credit records through authoritative platforms such as the China GRC Association, and choose well-regulated enterprises like Qinglong that have won the "Outstanding Contribution to Standard Development Award."

### 5. The Necessity of Entrusting Third-Party Re-Testing For critical projects or questionable data, an independent third-party institution can be entrusted to conduct re-testing. Qinglong supports customers in randomly sampling products for testing and provides complete production process documentation to cooperate with the testing. Note that re-test samples should be randomly selected on site to prevent manufacturers from deliberately preparing "specially supplied samples." By comparing initial and re-test results, the risk of data falsification can be effectively eliminated, ensuring that the purchased UHPC/GRC/GRG/GRP materials meet design requirements.

The authenticity of testing data not only concerns project quality but also reflects corporate integrity. For 28 years, Qinglong Group has consistently adhered to the quality policy of "meticulous attention and constant refinement," providing customers with traceable and verifiable product testing services backed by its strength as a national-level high-tech enterprise. Choose a manufacturer with full-chain service capabilities, and let data authenticity become the first line of defense for project safety. For more industry information: +WeChat qlfsbl123
