Scratch Hardness Tester through-scratching offer variable test speed testing equipment for quality management Technical Description

The optimised scratch hardness tester LINEARTESTER 249 is intended, in addition to its original purpose of application, i. e. to establish the ability of a surfaces to resist damage by scratching, also for several other tests: - Scribe/Scratch tests - To and fro-cycle abrasion tests - Crockmeter tests - MEK tests, tests determining the resistance against solvents in general or wipe test, respectively. Principle of the Test The test panel is fixed onto a mobile slide by means of clamping rails. Above this slide and held on two metal pillars is a reciprocating beam bedded in a free-moving manner...

Asymmetric Inserts Description Technical Data Dimensions (L x W x H) Specimen dimensions Power supply Net weight Scratching force Medium test speed *> additionally covered with an extremly hard layer 1 long shaft, directly assembled 2) short shaft, only for using with the adapter set 3) only for using with the disc adapter of the universal adapter set 60/110 mm (with/without guide plate)

In addition to the standard range of test tools the Universal Adapter Set allows the use of a variety of additions tool inserts. In this way individual test problems with specific tool geometries deviating from established determinations can be solved in an easy manner. The adapter set consists of the following components: Universal shaft Round rod (5 mm diameter) made of stain-less steel, with an axial bore with internal thread (M2.5) at one end and a clamping area over the total length. The universal shaft is mounted on the load arm vertically; there the adapter described here-after can be...
