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, feature articles, and news for textile professionals. The Association also publishes the AATCC Journal of Research, [6] a bi-monthly ...
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 ...
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. [8] This method is based on the original guidelines established in Australia in 1994.
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.
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 United States Environmental Protection Agency (EPA) maintains and approves test methods, which are approved procedures for measuring the presence and concentration of physical, chemical and biological contaminants; evaluating properties, such as toxic properties, of chemical substances; or measuring the effects of substances under various conditions.
The test reports loss of mass to abrasion and impact, expressed as a percentage of initial sample mass. [7] Maximum acceptable loss for the base course of the road is 45%; the more demanding surface course must be 35% or less. [1] The test was developed by the city engineers of Los Angeles in the 1920s. [8]
If an instrument has no official published test method, or has a withdrawn (or historical) test method, then there is a problem with the instrument, often being poor precision. To assess a floor's slip resistance, a reliable, thoroughly researched (in interlaboratory studies) floor friction test method must be used, and then a minimum safety ...
