Paper, board and pulps. Standard atmosphere for conditioning and testing and procedure for monitoring the atmosphere and conditioning of samples Ingestion-build-205840 BS 4258-12 on sampling techniques1 Scope 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 conditioning of laboratory prepared handsheets in accordance with ISO 52691, the standard atmosphere is that defined in this International Standard but the procedure is different1).
