1.2 These test methods are restricted to instrumented hot tack testing, requiring a testing machine that automatically heatseals a specimen and immediately determines strength of the hot seal at a precisely measured time after conclusion of the sealing cycle. An additional prerequisite is that the operator shall have no influence on the test after the sealing sequence has begun.To achieve vacuum level sealing, a maximum surface roughness of 16 μin. (0.41μm) has been recommended.3 Therefore, sealing surfaces on the test fixtures had to have surface finishes of 16 μin. or better. The sealing surfaces on both sides of the interface also had to be precisely aligned so that the amount of compression on the seal test
