This International Standard specifies a method for the determination of the absorbance at ultraviolet wavelengths of animal and vegetable fats and oils.

This International Standard specifies a method for calculating the recyclability rate and the recoverability rate of a new road vehicle, each expressed as a mass fraction of the vehicle. Under this procedure, performed by the vehicle manufacturer when a new road vehicle is put on the market, potentially, the vehicle can be recycled, reused or both (recyclability rate), or recovered, reused or…

This International Standard specifies the methods to be used to determine the content of 5-ethylidenenorbornene (ENB) or dicyclopentadiene (DCPD) in ethylene-propylene-diene (EPDM) terpolymers in the 0,1 % to 15 % range. ENB and DCPD are dienes introduced into ethylene-propylene rubbers to generate specific cure properties. Since high precision for diene content determination is important, a…

This Iinternational Standard specifies a method of obtaining a representative sample from a lot of paper or board, including solid and corrugated fibreboard (see ISO 4046:1978), for testing to determine whether or not its average quality complies with set specifications. It defines the conditions which apply when sampling is carried out to resolve disputes between buyer and seller relating to a…

This International Standard applies to the maintenance of AGL constant current series circuits. This International Standard: · covers constant current series circuits for AGL installed at aerodromes and heliports; · concentrates on providing the safety requirements for the maintenance of an AGL constant current series circuit. It is recognised that AGL constant current series circuits of…

This International Standard specifies the requirements for environmentally acceptable hydraulic fluids and is intended for hydraulic systems, particularly hydraulic fluid power systems. The purpose of this International Standard is to provide guidance for suppliers and users of environmentally acceptable hydraulic fluids, and for the direction of original equipment manufacturers of hydraulic…

This International Standard establishes the terminology for soil stabilizers used in road construction and pavement works. It provides the terminology for the machine and its components, also the definitions of operation principles and parameters. This International Standard also establishes the parameters required for the technical characteristics of the whole machine and its components, such as…

This International Standard specifies a method for determining the compressive properties of plastics under defined conditions. A standard test specimen is defined but its length may be adjusted to prevent buckling under load from affecting the results. A range of test speeds is included. The method is used to investigate the compressive behaviour of the test specimens and for determining the…

This International Standard specifies a method for the determination of the residual technical hexane content of animal and vegetable fats and oils. The method is suitable for the determination of hexane contents between 10 mg and 1 500 mg per kilogram of fat or oil. The method is not applicable to marine oils

This International Standard specifies requirements for enclosures and other protective measures used to minimize mechanical hazards produced by the rotor in the unbalance measuring station of centrifugal (rotational) balancing machines. The hazards are associated with the operation of balancing machines under a variety of rotor and balancing conditions. This International Standard defines…
