Abstract

Specifies the standard atmosphere for conditioning and testing pulp, paper, and board, and also the procedures for measuring the temperature and relative humidity. For the conditioning of laboratory prepared handsheets in accordance with ISO 5269-1, the standard atmosphere is that defined in this standard, but the procedure is different. Annex A covers the measurement of temperature and relative humidity. Annex B (informative) describes the interdependence of temperature and relative humidity. This second edition cancels and replaces the first edition (1977) which has been technically revised.
