White Resistance To Scratching Apparatus

RESISTANCE TO
SCRATCHING APPARATUS :-For Decorative Lamination Sheet (As
Per IS 2046:1995) is specifically
designed for Laboratory Testing of Decorative Lamination Sheet.


The minimum load applied to a diamond
scratching point a defined geometry which produces a continuous surface mark visible to
naked eye, corrected if necessary, if the resistance to scratching of the decorative laminated sheet under
test.

Minimum load is determine by applying
successively decreasing loads to the diamond point and examing to the mark produce.

CONSTRUCTINOVA MAKE RESISTANCE TO
SCRATCHING APPARATUS For Decorative Lamination Sheet
(As Per IS 2046:1995) is a digital unit
consisting of direct digital display of the load in gm/N (Table
provided on the unit).
A freely rotating supporting motorized
turn table rotating at the speed of 5 +/- 1 RPM adjustable legs are
provided for leveling.
A sidearm with the separate weight is
provided. A holder for diamond mounted is fitted on side arm.
Hemispherical diamond scratching point
with a point radius of 0.090 N +/- 0.003mm and angle of 90
Deg, C +/- 1 Deg. C is mounted in the
holder with the flat part on the leading side.
The system is also provided with side
arm resting device.
