Tensile Testing Machines for special sample fixture processing
For the test standards have fixture related detailed provisions, should be strictly in accordance with the standard, the design of the fixture specified in the standard. Such as finished product test, 90° stripping, jacking, ring stretching, etc.
For the finished product sample test without detailed standards, the relevant fixture should be selected or designed according to customer needs.
For no special provisions in the standard, the customer has no requirements, the general selection of clamping fixtures, pneumatic fixtures are recommended. Such as 180° peel, lap, tear, etc.
It should be noted that there are two kinds of double-sided tightening and single-sided tightening of the clamping fixture, and it is best to use double-sided tightening for samples requiring different positions of the upper and lower clamping jaws of the 180° peel and lap joints. However, the pneumatic fixture is mostly single-sided clamping, but there are also fixtures with adjustable fixed surface position.
