Iultcs Rubbing Color Fastness Tester - China

This instrument is used to test the rubbing fastness of leather surface under dry friction and wet friction as well as other test conditions.

Basic principles: the square wool felt on friction head (with or without extra balance weights) makes reciprocating friction with leather (stretched or not stretched) on the friction platform for reciprocating friction.

After a certain number of friction times, compare the wool felt with gray card and rate the color fastness level.

Standards

ISO 11640 Leather -- Tests for colour fastness -- Colour fastness to cycles of to-and-fro rubbing.

SATRA PM 173 Reference standard of footwear testing content and methods.

QB/T 2537-2001 Leather -- Tests for colour fastness --Colour fastness to reciprocating rubbing.

DIN 4843 Safety Footwear; Safety Requirements, Testing

Consumables

Friction material:

White wool felt, size 15mm × 15mm.

The punched pure wool felt piece should meet the following requirements: pH of water extract between 5.5 ~ 7.0; mass per unit area (1750 ± 100) g / m2, thickness (5.5 ± 0.5) mm.

Technical Parameters 1, Test bench: a horizontal metal platform; a holder for fastening the leather to the platform, leaving approximately 80mm exposed; a device with which the leather may be extended 10% to 20% linearly in the direction of rubbing (sample size 120mm × 20mm).

2, Test column: weight (500 ± 25) g.

It can be moved, but also firmly fixed.

including:

A) Test head area: 15mm × 15mm;

B) Device for adjusting the test head to bring the felt pad into horizontal contact with the test platform;

C) Load bearing blocks: (500 ± 10) g.

After loading, the total mass of the test column is 1000g;

D) Adjustment device: adjust the test column up and down so that the test head makes horizontal contact with sample.

3, Device that drives test bench for reciprocating motion: test head makes forward-backward motion with a stroke of 35mm ~ 40mm at a frequency of (40 ± 2) cycles / min.

4, Counter: LCD digital display, round-trip as one time, the number of cycles can be set to 5 to 500 times.

5, Device that can adjust the test column in the horizontal direction (optional): the test head can be rubbed against the leather samples at 2 to 3 different angles.
