Crocking
Applus+ Reliable Analysis provides accurate crocking testing that helps textile and medical device manufacturers ensure their dyed and printed fabrics resist color transfer during rubbing or use. Our expanded capabilities build directly on our existing AATCC 8 and ISO 105-X12 accreditations using proven crock meters and color evaluation equipment already operating in our ISO/IEC 17025-accredited laboratory. You receive reliable ratings for medical scrubs, gowns, drapes, activewear, and technical textiles where colorfastness to rubbing is essential for appearance and patient safety.
Crocking testing measures how much color transfers from a fabric to another surface through dry or wet rubbing. This is particularly important for medical scrubs, surgical gowns, patient apparel, and workwear where even minor color migration can affect hygiene perception, professional appearance, or regulatory compliance. At Applus+ Reliable Analysis, we perform these evaluations with our standardized crock meters, controlled wet and dry conditions, and precise color measurement tools already running under our accredited scope. Our team tests both the specimen and multi-fiber adjacent fabric, providing clear visual ratings (Grade 1–5) and instrumental ΔE values when needed.
Common Crocking Textile Testing Standards
AATCC 8 Colorfastness to Crocking
Reliable Analysis performs AATCC 8 crocking testing using our standardized crock meters already accredited for this method. We rub dyed or printed textiles against white crock cloth under controlled dry and wet conditions and rate color transfer. This test is essential for medical scrubs, gowns, drapes, activewear, and technical textiles where colorfastness to rubbing is critical. You receive fast, ISO/IEC 17025-accredited results with clear ratings that help ensure your materials maintain appearance during use and cleaning.
ISO 105-X12 Textiles Color Fastness to Rubbing
We run ISO 105-X12 rubbing fastness testing on our current crock meters and color evaluation tools. Textiles are assessed for color transfer to adjacent fabrics under dry and wet conditions. This method supports international medical apparel and performance fabric manufacturers. You benefit from harmonized, globally recognized results that align with your export and quality standards.
AATCC 8 Abrasion Durability (Post-Abrasion Crocking)
Reliable Analysis combines AATCC 8 crocking testing with pre- or post-abrasion using our Stoll and Martindale equipment. We evaluate how well colorfastness holds up after mechanical wear on medical scrubs and workwear. This integrated approach gives manufacturers realistic performance data that reflects actual use. You receive comprehensive results from one accredited lab.
GMW14296 / GMW14334 Crocking for Textiles
We perform GMW14296 and GMW14334 crocking testing on our accredited crock meters for GM-specified textiles. Specimens are rubbed under controlled conditions and rated for color transfer. This ensures materials meet GM performance standards for medical and automotive textiles. You gain efficient, OEM-compliant results integrated with our broader color and mechanical testing services.
FLTM BI 113-02 / BI 113 Series Crocking
Reliable Analysis executes FLTM BI 113 series crocking testing using our current equipment for Ford-specified textiles. We assess color transfer under dry and wet rubbing conditions. This supports medical and interior fabric qualification. You receive reliable results from a lab already experienced with Ford chemical protocols.
LP-463KC-21-01 Crocking Resistance
We run LP-463KC-21-01 crocking resistance testing on our current setups for textiles and coated materials. The method evaluates color transfer under Chrysler/FCA conditions. This supports medical and technical textile programs. You benefit from consistent data aligned with FCA requirements and our full mechanical testing capabilities.
SAE J948 Crocking Component
Reliable Analysis incorporates crocking evaluation into SAE J948 abrasion testing on our current equipment. Textiles are assessed for color transfer during or after abrasion. This supports automotive and technical textile qualification. You receive clear, SAE-aligned data integrated with our broader wear and colorfastness program.
VDA 230-223 Crocking Assessment
We perform VDA 230-223 testing with focused crocking assessment using our crock meters and color tools. Textiles are evaluated for color migration under European automotive and medical conditions. This method supports manufacturers requiring VDA compliance. You benefit from reliable results that integrate with our chemical and abrasion testing services.
AATCC 116 Colorfastness to Crocking: Rotary Vertical Crockmeter Method
Reliable Analysis performs AATCC 116 rotary vertical crocking testing using our specialized crock meter. The method provides precise evaluation of color transfer on high-performance and medical textiles. This supports applications needing detailed rubbing fastness data. You receive accurate, standards-aligned results from our colorfastness program.
