1. Unuo ASTM D395 Compression Set Fixture Method A Features

• The structure is made of high-strength steel whose surface is with
  anti-rust plating process;
• The test platform is made of stainless steel, which is anti-rust and strong;
• The equipment is equipped with 9 stainless steel sample splints, which
  can test multiple sets of samples at the same time;
• High-performance spring, stable and long spring life;
• High precision dial indicator;

2. ASTM D395 Method A Compression Set Fixture Principle

Cut the sample and measure the thickness of the sample. Place the samples on the sample plate and sandwiched between the two plates. After the sample is compressed for a period of time by a preset pressure, the sample is removed and left for a certain period of time. Measure the thickness change of the sample and calculate the percentage change in thickness before and after the test. Check ASTM Method B Here

3. Tips for Compression Set Apparatus

•  Samples are prepared strictly in accordance with the requirements of the standard before testing, and can be single or multiple stacked to the specified thickness (up to three stacked);
• When using the device, slowly turn the handle and apply pressure slowly to prevent the sample from being excessively compressed due to instant pressure;
• When using this equipment for testing, it should be allowed to stand for a certain period of time in a controlled, constant temperature and humidity environment, and after the test is finished and the sample is taken out, the sample recovery period should also be restored in the environment;
• The thickness gauge is also required for this test;
