What is a hardness test block?
Calibrated test blocks are an integral part of hardness testing. They ensure accuracy, integrity and traceability of hardness testing processes. They are used to verify instruments performance and provide a means for performing indirect instrument calibrations. CRITICAL. Trusted in the Industry.
What is Relay test block?
Relay Test Block is moulded out of high grade phenolic resin (Bakelite). It is designed for on-load testing of relays and meters without disturbing panel wiring. The housing consists of ten pairs of silver plated contacts.
What are hardness test blocks made of?
Our hardness test blocks are manufactured by selected steel and aluminium producers with excellent experience in the production of homogeneous material.
What is a PK block?
Type PK-2 test blocks are essentially 4-pole and 6-pole jacks, provided with molded Textolite covers that have internal plug contacts, which make a through connection when the cover is in place. The contacts in the blocks are of the line- pressure type and provide positive contact with minimum contact resistance.
How do I test my hardness?
A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter.
How many types of hardness tests are there?
There are six main hardness tests that can be carried out: Vickers, Rockwell, Brinell, Mohs, Shore and Knoop. Which one to apply depends on the type of material to be tested and the equipment available.
What is the hardness test called?
The Mohs hardness test is one of the earliest attempts at defining and comparing the hardness of mineral materials. The Mohs scale consists of values from 1 to 10, which correlate with the ability of the test material to withstand scratching by progressively harder minerals.
