The electrical-plug connector specified in this International Standard is intended to be used under working conditions such that the connector cannot be damaged by external action (for example

ceramic shot or glass beads

Experimental data for uncertainty estimation can be provided either by a single experimental design in a direct approach or by a combination of different experimental designs in an indirect approach

binders for paints and varnishes

Aerosol filtration can be used in diverse applications

Anaesthetic and respiratory equipment. Peak expiratory flow meters for the assessment of pulmonary function in spontaneously breathing humans Ingestion-build-205840 The electrical-plug connector specified in1 Scope This International Standard specifies requirements for peak expiratory flow meters (PEFMs) intended for the assessment of pulmonary function in spontaneously breathing humans. This International Standard covers all devices that measure peak expiratory flowrate in spontaneously breathing humans either as part of an integrated lung function device or as a stand alone device.
