5 Test methods
5.1 General inspection requirements
5.1.1 Test environment conditions
Unless otherwise specified, the environmental conditions of the test shall be a
temperature of 23°C±5°C and a relative humidity of 50%±10%. Each of the following
performance tests shall comply with this environmental condition. Room temperature
shown below is the environmental condition.
5.1.2 Pretreatment
Before the test, the specimen shall be placed in an environment with a temperature of
23°C±2°C and a relative humidity of 50%±10% for at least 48h. For painted parts, it
needs to be placed in an environment with a temperature of 23°C±2°C and a relative
humidity of 50%±10% for at least 168h.
5.1.3 Appearance
Visually inspect.
5.2 Performance test requirements
5.2.1 Dimension stability
5.2.1.1 Specimen
