Product Details
The variable rest (extension rest) provides adjustable support for long test pieces that overhang the tester, keeping them level and stable per ISO 6508.
It carries the overhanging end of a long specimen so the piece stays level and the test surface remains perpendicular to the indenter throughout the load cycle — the standard emphasizes that the specimen must be supported so that it cannot shift under load. Beyond this documented use, no further published specification exists for the item; contact us for details.
