This International Standard specifies the standard atmosphere for conditioning, and for testing pulp, paper and board, and also the procedures for measuring the temperature and relative humidity. For the condilioning of laboratory prepared handsheets in accordance with ISO 5269-1, the standard atmosphere is that defined in this Inter-national Standard but the procedure is different. note:1) ISO 5269-1 requires pulp handsheets to be conditioned by desorption of moisture, whilst ISO 5269-2 requires drying followed by conditioning by sorption of moisture.
