OS GSO 137:1991 Scope
This standard is concerned with the methods of conditioning and testing all plastics under approximately normal ambient atmospheric conditions, and for rigid cellular plastics the methods for the determination of the linear dimensions of sheets, blocks or test specimens of cellular material, and the method for the determination of dimensional stability of these materials when subjected to specific conditions of temperature and relative humidity. Special atmospheres applicable to a particular test or material or simulating a particular climatic environment are not included in this standard.
