AATCC provides test method training at its laboratories, at members’ facilities, online, and in more than 10 countries around the globe. AATCC also offers test method proficiency programs and quality control products for use in conducting its test methods. AATCC publishes a bi-monthly magazine, AATCC Review, [5] containing technical articles
During World War I, when the Atlantic blockade prevented European dyes from entering America and the newly formed American dye manufacturers struggled to provide consistent products, the need for American textile testing methods became apparent. [7] The AATCC has developed over two hundred textile standards, test methods, evaluation procedures ...
Absolute values of fading will depend on light intensity. Relative values of fading, comparing the sample with the standard blue test strip, will depend less on intensity. For example, if a pigment is rated as "BW5" it can be expected to fade to the same degree as strip number 5 on a bluewool test card, for any specific light exposure.
Developed in 1998 by Committee RA106, the testing standard for sun protective fabrics in the United States is the American Association of Textile Chemists and Colorists (AATCC) Test Method 183. [7] This method is based on the original guidelines established in Australia in 1994.
The test method evaluates the thermal resistance and water vapor permeability of fabrics, which bear on the garment's comfort. [115] [116] ISO 11092:2014 (the test for physiological effects — Test for measuring thermal resistance and water-vapor resistance) [117] ASTM F1868 (test for measuring thermal and evaporative resistance) [118]
The Test Methods Regulation is a Regulation (European Union) No. 440/2008 of May 30, 2008. It, and its subsequent amendments, define tests, testing of chemicals for the REACH Regulation . They are based on the OECD Guidelines for the Testing of Chemicals .
The reagents in this method tend to stain the test tubes. Same test tubes cannot be used since the stain would affect the absorbance reading. This method is also time sensitive. When more than one solution is tested, it is important to make sure every sample is incubated for the same amount of time for accurate comparison. [18]
BCA protein assay in a 96 well plate. The bicinchoninic acid assay (BCA assay), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein assay or ...
