Acoustics — Measurement procedures for ducted silencers — Insertion loss, flow noise and total press...
Specifies the substitution method for determining the insertion loss. The measurement procedures are intended for laboratory measurements on silencers but may also be used for in situ measurements on silencers if the requirements of ISO 7235 can be met. Applies to silencers for ventilating and air-conditioning systems. Does not apply to reactive silencers used for motor vehicles.
Paper, board and pulps — Standard atmosphere for conditioning and testing and procedure for monitori...
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…

Water quality — Determination of dissolved oxygen — Electrochemical probe method
Includes a procedure by means of an electrochemical cell which is isolated from the sample by a gas permeable membrane. Depending on the type of probe employed measurement can be made either as concentration of oxygen, percentage saturation or both. The procedure is suitable for measurements made in the field and for continuous monitoring and in the laboratory. It is the preferred procedure for…
This first edition cancels and replaces the first edition of the Technical Report ISO/TR 5007:1980. Specifies a method for measuring and evaluating the effectiveness of the seat in reducing the vertical whole-body vibration transmitted to the operator of an tractor. Applies to seats fitted to tractors within specified classes, each class being defined as a group of tractors having similar…
