For each test, the specific steps will be different, and the corresponding test standards or methods need to be referred to. Some commonly used standards or methods include: أستم, ايزو, جيجابايت/ت, إلخ. Attention should be paid to the accuracy and repeatability of the instrument, as well as the preparation and handling of the sample during the test.
