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–
