JIS Crockmeter / Textile Abrasion and Rubbing Fastness Tester
The JIS Crockmeter is a precision laboratory instrument designed according to the Japanese Industrial Standards for textile colorfastness testing, specifically the “Colorfastness to Rubbing” method (JIS L0849). It evaluates the rubbing and abrasion resistance of dyed textile products. By exchanging optional accessories, the instrument can also test flocked fabrics, artificial leather, printed paper, inks, coatings, and other materials, making it a versatile solution for multiple material types.
Application
This tester is suitable for assessing rubbing and abrasion fastness in:
(1) Dyed textiles and fiber products;
(2) Flocked fabrics for evaluating flock adhesion strength;
(3) Artificial leather for color transfer and rubbing resistance;
(4) Printed papers, inks, and coatings for abrasion and rub-resistance testing;
(5) Quality control, research, and development laboratories in textile, leather, and printing industries.
Standards
The instrument conforms to the following international and national standards:
(1) JIS L0849 – Textiles. Test Methods for Color Fastness. Rubbing Fastness Method;
(2) JIS L1084 – Textiles. Test Methods for Color Fastness of Dyed Fabrics;
(3) JIS P8136 – Testing Methods for Rubbing Fastness and Abrasion Resistance.
Features
Six test stations enable multiple samples to be tested simultaneously for efficiency.
Curved test table and interchangeable friction heads provide flexibility for different materials.
Transparent safety shield ensures operator protection while maintaining visibility.
Optional friction heads (1.5 R rounded, sharp-angle, flat 20×20 mm) accommodate a wide range of material types, including flocked fabrics and printed surfaces.
Load weights are provided (300g, 500g, 800g) for precise and reproducible test conditions.
Compact design allows easy installation and laboratory use.
