3 Terms and definitions
The terms and definitions defined in GB/T 32110 apply to this document.
4 Test principle
4.1 diameter
Use a platen or laser diameter tester to measure the diameter of the sample, record the test value separately, and calculate the total value of all the samples.
The mean value is the diameter of the sample in millimeters (mm).
4.2 fixed length weight
Prepare a sample of a certain length using the specified sample preparation device, weigh the sample on the analytical balance, and specify all the samples in the specified quantity.
The ratio of the arithmetic mean of the weight to the length of the prepared sample is the fixed length weight of the sample in grams per 100 meters (g/100 m).
5 test environment
5.1 Overview
The test shall be carried out in an environment of suitable temperature and relative humidity. The test environment is characterized by temperature, relative humidity and deviation (%). temperature
The unit of measure is Celsius (°C).
According to the requirements of the product standard, choose any one of Environment A and Environment B. Each choice depends on the general habits of the industry.
Depending on the application and the application, the choice of which environment to test should be recorded in the test report.
5.2 Environment A
The specific conditions are as follows.
