This standard specifies the method for determining compressive performance by applying a static compressive load to a sample p>
This standard is applicable to rigid and semi rigid plastic materials and filled modified plastic materials, not to fiber reinforced materials and rigid foam plastics p>
2 Reference Standards
GB 2918 Plastic Specimen Condition Adjustment and Standard Environment for Specimens
3 Terminology
3.1: Compressive Stress: The compressive load per unit of original cross-sectional area of the specimen at any time during the compression test process.
. In megapascals p> 3.2 Compressive strain: The change in unit original height of the specimen. Expressed as a ratio of the same dimension p> 3.3 Compressive deformationFunction of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
