Technical Description SCRATCH HARDNESS TESTER 413

Product catalog summary

Overview: The document provides a detailed technical description of the Scratch Hardness Tester 413, a device used for assessing the scratch hardness of materials, particularly in quality management applications.

Specifications:

The tester allows for the identification of fine tendencies in scratch hardness changes and provides surface quality descriptions in numerical values.
It features a fine graduation of scratch load adjustment with increments as small as 0.01 N.
Dimensions are 220 x 450 x 210 mm, with a net weight of approximately 3.8 kg.
Operates at 5 min^-1 at 50 Hz or 6 min^-1 at 60 Hz, with power supply options of 230 V/50-60 Hz or 110 V/50-60 Hz.
Accommodates specimen sizes up to 100 x 100 x 22 mm or 140 ø x 22 mm.

Test Principle: The specimen is clamped on a turntable, and a test tool is fixed on a load arm with adjustable weight, allowing regulation of pressure exerted on the specimen. The resistance is visually evaluated from the score mark.

Technical Data: The tester is supplied with a Manufacturer’s Certificate M in accordance with DIN 55 350-18, detailing actual and setting values of rotational speed and test load, product identification, and calibration status.

Order Information:

Basic instrument includes a load arm, weights for 1 N and 10 N ranges, counterweight with spirit level, box level, magnifying glass, screwdriver, carrying case, and instructions manual.
Various test tips are available, including diamond test tips and those conforming to standards like ISO 1518 and DIN EN 438-2.

Applications:

Decorative laminated sheets (HPL) and paints/coatings are tested for micro scratch hardness according to ISO 4586-2 and DIN EN 438-2.
Scratch hardness for paints and coatings is tested according to ISO 1518, Bosch, Opel, and van Laar standards.

Key Parameters: The essential test parameters include a measuring range of 0 - 10 ± 0.1 N, with various test tips specified for different applications.
