BAIJIAN - Third party testing organization
Visual quality inspection of inspection items: Check the surface of the glass for defects such as scratches、 bubbles、 pits、 and spots、 and ensure that their impact is consistent with the actual use situation. Strength testing: Testing whether the glass of glass guardrails meets the design requirements for wind and thrust load resistance characteristics、 which are represented by the central bending surface slope、 vertex displacement、 and critical tensile and compressive yield strength generated under a given load. Fragmentation performance test: tests whether glass undergoes crack propagation within or adjacent to the entire glass under different loads、 and whether sharp fragments will form after fragmentation. Installation strength test: The bearing capacity of glass guardrails should be related to the safety of operators. By testing the connection strength of its installation point、 ensure the stability and safety of the guardrail. Environmental testing: Check whether glass guardrails contain harmful substances and whether they comply with environmental requirements and national standards. The detection scope includes indoor glass guardrails、 outdoor glass guardrails、 staircase glass guardrails、 bridge glass guardrails、 high-altitude glass guardrails、 balcony glass guardrails、 etc. Relevant reference standard specifications GB/T 903-2019: Colorless optical glass GB/T 1347-2008: Chemical analysis methods of sodium calcium silicate glass GB/T 1549-2008: Chemical analysis methods of fiber glass GB/T 2680-1994: Visible light transmittance of building glass、 direct sunlight transmittance、 total solar transmittance Determination of UV transmittance and related window glass parameters GB/T 3284-2015: Chemical composition analysis methods of quartz glass GB/T 3385-2001: Non destructive strength testing of tempered safety glass for ship's side windows and rectangular windows Stamping method GB/T 3681-2011: Natural sunlight weathering of plastics Exposure Test Method for Solar Climate Aging after Glass Filtration and Fresnel Ear Lens Accelerated Solar Climate Aging GB/T 4121-2014: Test Method for Thermal Discoloration of Quartz Glass GB/T 4548.2-2003: Determination and Grading of Water Erosion Resistance of Glass Containers by Flame Spectroscopy GB/T 5137.1-2020: Test Methods for Automotive Safety Glass Part 1: Mechanical Property Testing Purpose of Processing Test Reports 1: Evaluation of Product Quality; 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. The above article is a partial list. For more testing needs and details、 please consult the online consultant of the free consulting agency: 18501763637
