Product Description

Caltech India offers BGD 509 Pendulum Hardness Tester. A pendulum resting on a coating surface is set into oscillation and the time for the oscillation amplitude to decrease by an amount specified in this International Standard is measured. The shorter the damping time, the lower the hardness.

Two test procedures are considered in some detail, namely those of Knig and Persoz. (The Persoz and Knig methods differ by the period and amplitude of the oscillation. The Persoz test measures the time taken for the amplitude of oscillation to decrease from 12° to 4°; the knig from 6° to 3°.)

The instruments embody the same principle that the amplitude of oscillation of a pendulum touching a surface decreases more rapidly the softer the surface but differ in respect of dimensions, period and amplitude of oscillation.

BGD 509 Pendulum Hardness Tester is the newest product which can be used in accordance with the following National and International Standards: ISO 1522 which supersedes ASTM D4366; BS 3900 E5; DIN 53157; NBN T22-105; NF T30-016.

Its a simple to use instrument and can be supplied in one of three model types: Persoz, knig, Persoz and Knig combined.
