What is Aatcc standard?
The American Association of Textile Chemists and Colorists (AATCC) publishes standards for test methods of fiber analysis, colorfastness, color measurement and other textile elements. More than 200 accepted procedures are available. AATCC standards ensure you can: Improve durability.
What is AATCC 42?
AATCC 42 Water Resistance is applicable to any textile fabric which may or may not have been given a water-resistant or water-repellent finish. The test measures the resistance of fabrics to the penetration of water by impact, and thus can be used to predict the probable resistance of fabrics to rain penetration.
What is Aatcc test method?
The AATCC 100 test method method is designed to quantitatively test the ability of fabrics and textiles to inhibit the growth of microorganisms or kill them, over a 24 hour period of contact.
What Aatcc 135?
AATCC 135-2018 is intended for the determination of dimensional (length and width) changes of fabrics when subjected to home laundering procedures. Four washing temperatures, three agitation cycles, and four drying procedures provide standard parameters to represent common home care options.
What are ASTM standards used for?
How are ASTM standards developed? A standard is a document detailing specific requirements for the quality and safe use of materials from a wide range of industries such as metals, paints, plastics, textiles, petroleums, and consumer products.
What is ASTM f1671?
Description. This test method is used to measure the resistance of materials used in protective clothing to penetration by blood-borne pathogens using a surrogate microbe under conditions of continuous liquid contact. Protective clothing material pass/fail determinations are based on the detection of viral penetration.
What is ASTM F1670?
ASTM F1670 and ISO 16603 are “screening-tests” that evaluate the resistance of a material to synthetic blood penetration [ASTM 2003a; ISO 2004a]. The synthetic blood used for these tests is a mixture of cellulose, coloring, buffer solution, and stabilizing agents.
How do you find the mass per unit area of fabric?
1.1 Discussion—Fabric mass per unit area is expressed either as grams per square metre (ounces per square yard), or grams per linear metre (ounces per linear yard). Fabric mass is also sometimes expressed inversely as linear metres per kilograms (yards per pound) with the fabric width stated.
Who sets ASTM standards?
Who develops ASTM standards? ASTM has over 30,000 volunteer members from more than 140 countries around the world who are producers, users, consumers and general interest parties. These members write ASTM standards through their service on one or more of our 140-plus technical committees.
