Textile testing seems to be very popular at the moment, partucularly ASTM D5034 the grab test and ASTM D2261 the tear test.  Pneumatic grips are ideal for this type of test with their constant clamping load, which when combined with rubber faced jaws they give a good coefficient of friction with most materials helping to eliminate slippage in the jaws.  Because most clients are performing several different tests with different jaw sets, quick release jaws  combined with space in the grip body, above the jaws, for finger room, are frequently requested.  Ball burst test fixtures to ASTM D6797 and ASTM D3787 are often ordered by customers to compliment the tensile tests.  Our range of pneumatic grips and puncture fixtures can be used to perform these tests with modifications to suit the customer onrequest.
