test items and standards
Mechanical performance test
Tensile strength test: measure the maximum tensile strength of interior materials to ensure that they have sufficient bearing capacity and durability in daily use.
Tear strength test: evaluate the resistance of materials when subjected to tearing force.
Peel strength test: test the adhesion between different material layers.
Aging resistance test
Light fastness test: simulate the performance of materials under the influence of sunlight to ensure that they will not fade or deteriorate even after long-term exposure to sunlight.
Heat resistance test: evaluate the performance stability of materials under high temperature conditions.
Weather resistance test: evaluate the durability of materials in natural environments.
Corrosion performance test
Evaluate the resistance of materials to chemicals, such as acids, alkalis, salts, etc.
Combustion performance test
Test the fire resistance of interior materials to ensure that the spread of fire can be delayed in the event of a fire.
ELV test
Detect whether interior parts contain banned or restricted substances, such as heavy metals, banned chemical components, etc.
Color and color fastness test
Light fastness test: evaluate the color stability of materials under light.
Perspiration color fastness test: Test the color stability of interior materials under the action of sweat.
Rubbing color fastness test: Test whether the color of interior materials changes under the action of friction to evaluate the color stability after long-term use.
Other performance tests
Breathability test: Evaluate the breathability of materials.
Stain resistance and cleaning ability test: Evaluate the tolerance of interior materials to stains such as grease and coffee and the ease of cleaning.
Safety test: The expert team evaluates the intensity and nature of the odor in the car to ensure a comfortable riding experience; evaluate the release of VOCs from interior materials at high temperatures, and whether condensation will occur under different humidity conditions, affecting the driver's vision.


Testing methods and processes
Sample acceptance
According to the contract requirements, the test samples entrusted by the customer are received, and the name, quantity, specifications, etc. are confirmed.
The test samples are photographed, numbered, and distributed to the test engineer for testing.
Quality test project testing
According to the contract requirements, the samples are tested for various quality test items.
Use professional testing equipment and instruments to test in accordance with relevant standards and specifications.
Report preparation
Based on the test results, a detailed test report is prepared.
The report should include information such as test items, test methods, test results and conclusions.


Notes
Choice of testing standards
Automotive interior testing standards are usually formulated based on different countries or regions, industry standards and specific product implementation standards.
When selecting testing standards, ensure that they are consistent with product requirements, customer needs and laws and regulations.
Calibration and maintenance of testing equipment
Ensure the accuracy and reliability of testing equipment, and perform calibration and maintenance regularly.
Use testing equipment and instruments that meet the requirements for testing to ensure the accuracy of test results.
Training and management of testing personnel
Provide professional training for testing personnel to ensure that they are familiar with testing standards and operating methods.
Strengthen the management and supervision of testing personnel to ensure the standardization and fairness of testing work.


In summary, the testing of automotive textile interior parts involves multiple aspects and links, and needs to be carried out strictly in accordance with relevant standards and specifications. Through comprehensive testing, the quality and safety of automotive textile interior parts can be ensured, and consumer satisfaction and trust can be improved.
