BAIJIAN - Third party testing organization
The testing items for curing agents vary slightly due to their types. Generally speaking、 the following are some common testing items for curing agents: curing efficiency testing、 which measures the quality of the curing effect after the curing agent interacts with the cured substance. Relative molecular weight and chemical composition testing mainly measures the molecular weight of the curing agent and whether its chemical composition meets the standards. Solvent determination involves detecting the volatility and other characteristics of curing agents. PH and acid value detection、 testing the acid-base properties and acidity or alkalinity level of the curing agent. Detection of heavy metals and organic pollutants、 as they may pose potential threats to the environment and human health. Measurement of physical and mechanical properties、 including hardness、 wear resistance、 and tensile strength. These tests can help determine the suitability and strength of the curing agent to the material. Performance and application characteristics testing、 such as moisture sensitivity、 temperature resistance、 adhesion、 and corrosion resistance. These tests can help determine the application range and usage environment of the curing agent. The detection scope includes paint curing agents、 glue curing agents、 soil curing agents、 epoxy curing agents、 polyamide curing agents、 reactive curing agents、 oxidation curing agents、 light curing agents、 accelerators、 free radical curing agents、 tanning curing agents、 etc. Relevant reference standards and specifications GB/T 21872-2008 Sulfonic acid curing agent for casting self hardening furan resin CJ/T 526-2018 Soft soil curing agent CJJ/T 286-2018 Technical standard for application of soil curing agent (with article explanation) HG/T 3875-2006 Phenolic amine (PAA) epoxy resin curing agent HG/T 5063-2016 Curing agent for solvent based polyurethane wood coatings GB/T 27807-2011 Curing agent for polyester powder coatings Purpose 1: To evaluate the quality of products; 2. Determine the product quality level、 i.e. the severity of defects; 3. Inspect the process flow and supervise the process quality; 4. Collect、 statistics、 and analyze quality data to lay the foundation for quality improvement and management activities; 5. Introduce arbitration inspection to determine the responsibility for quality accidents. The purpose of handling third-party testing reports is to obtain an independent、 objective、 and professional evaluation result to confirm whether the tested items or services comply with relevant regulatory standards、 quality requirements、 or technical specifications、 and to verify their safety、 reliability、 and performance. Third party testing reports are typically used in areas such as product certification、 market access、 supply chain management、 trade negotiations、 and dispute resolution. Precautions for Testing Report: Carefully read and understand each section after receiving the testing report. Ensure that there is a "research and testing special seal" and official seal in the report、 and check the anti-counterfeiting QR code to confirm its effectiveness. Confirmation information: Verify whether personal or organizational information is accurate and accurate. If the report is not stamped with the "Research and Testing Special Seal" or official seal、 it is invalid. Pay attention to the test results: Focus on the summary and detailed information of the test results. If in doubt、 consult relevant engineers and it is strictly prohibited to alter the report. Pay attention to the reference range: Check the reference range of the test results to see if the results are normal. As the reference range varies depending on factors such as samples、 test methods、 reference standards、 etc.、 please contact our engineers to discuss your specific situation. Objection handling: If you have any objections to the test report、 please file an appeal within 15 days of receiving the report. Late appeals will not be accepted.
