The Standard Atmosphere for Textile Testing

Laboratory conditions for testing fibres, yarns and fabrics in which air temperature and relative humidity are maintained at specific levels with established tolerances. Textile materials are used in a number of specific end-use applications that frequently require different testing temperatures and relative humidity. Specific conditioning and testing of textiles for end-product requirements can be carried out using as below-

Standard Atmosphere for testing various materials

Materials	Temperature (℃)	Relative Humidity (%)
Textiles	21±1	65±2
Nonwovens including papers	23±1	50±2
Glass fibre for textile applications	21±1	65±5
