Annotation
PURPOSE AND SCOPE
This method describes a procedure for conditioning textile materials to moisture equilibrium with the standard atmosphere.
The standard atmosphere is defined as air maintained at a relative humidity of 65% and a temperature of 20oC. For the purpose of the procedures described in this method a variation of + 2% relative humidity and + 2oC from the defined standard atmosphere. Tests in which differences in the moisture content of the specimen will influence the results are carried out on material in moisture equilibrium with the standard atmosphere. (Note 1).
Note 1: When standard atmospheric conditions are not available, tests may be carried out under prevailing atmospheric conditions, but it must be recognized that the results observed may not correspond with the results that would be obtained in the standard atmosphere. In cases of uncertainty or dispute, all specimens shall be brought to moisture equilibrium with the standard atmosphere and tested in this condition.
