The clamping holding force values measured at – 0.85 vacuum and are related to the complete coverage of the clamping surface; the other values are related to the partial coverage of the clamping surface.

The vacuum levels are measured in the vacuum chamber underneath the METAPOR slab (air distribution channels). The clamping holding forces have been measured by pulling a suction cup in rectangular direction.

The tests have been made on clamping devices, each 300 x 210 mm, with a METAPOR material thickness of 10 mm.

The air has been evacuated with an ejector pump, model M200, manufactured by PIAB.
