Contains a method for measuring the airborne noise emitted by small air-moving devices such as those used for cooling electronic, electrical and mechanical equipment. Applicable to up to an airflow of one cubic metre per second and up to a fan static pressure of 750 Pa. Suitable for type tests; provides a method for manufacturers and testing laboratories to obtain comparable results.

Gives general guidance for the preparation of samples of essential oils submitted to a laboratory for analysis. Does apply to essential oils which are solid or partly solid at room temperature and cannot be analysed directly. The method cannot be used for samples for determination of water.

Provides a means for estimating the lethal toxic potency of the fire effluents produced from a material, while exposed to the specific combustion conditions of a laboratory fire model.

Spectrometric method for the determination of anionic surfactants by measurement of the methylene blue index (MBAS) in aqueous media. Suitable for drinking water, surface water and waste water. Does apply for laboratory scale and technical large-scale waste-water treatment plants.

Describes a laboratory method of measuring the vibrations at the handles of hand-held stone-working power tools and needle scalers. Establishes the magnitude of vibrations at the handles when operating on the artificial load.

Describes a laboratory method and in situ methods for the determination of the sound insulation performance of sound-protecting cabins. Applicable to sound-protecting cabins with a leak ratio smaller than 2 %.

Describes a laboratory method of measuring the vibrations at the handles of hand-held power rammers used in foundries, on building sites etc.. Establishes the magnitude of vibrations at the handles when operating on the specified load.

Gives a laboratory method for determining the flash-ignition temperature and spontaneous-ignition temperature of plastics using a hot-air furnace. Does not give a direct measure of the combustability or rate of burning of plastics. Replaces the first edition.

Describes a laboratory vibration mill procedure for the determination of the grain stability of calcined coke for the manufacture of carbon products used in the manufacture of aluminium.

Specifies a method for the laboratory measurement, the data analysis and reporting of the vibration transmissibility of gloves in terms of vibration transmission from a handle to the palm of the hand in the frequency range from 31,5 Hz to 1250 Hz.
