Establishes a standard layout for methods for the determination of volatile components and gives general information on these methods. Takes into account the general layout of methods of chemical analysis given in ISO 78/2 and the recommendations given in ISO 2718.

Describes a method applicable to products having inert gas content equal to or greater than 0,005 % (V/V). The principle is based on detection of inert gas from test portion s taken from the liquid or gaseous phase and analysis under such conditions that none of the gases are retained irreversibly by the stationary phase.

Specifies requirements for the footwear mentioned for use in chemical industry and in industrial plants and resistant to chemicals specified in this standard (sulphuric acid, hydrochloric acid and sodium hydroxide). In the case of chemicals other than those specified, the advice of the footwear manufacturer should be sought. It is recommended that footwear used in contact with chemicals should be…

This standard applies to chemically produced methanol with a purity of 99.85% by mass.

Describes a method based on the potentiometric titration of the chloride ions with standard volumetric silver nitrate solution in an acid medium and in the presence of acetone, using a silver electrode or a chloride or silver ion-selective electrode (measuring electrode) and a calomel or a mercury(I) sulphate electrode (reference electrode). Is a applicable to test solutions having chloride…

Specifies requirements and gives recommendations for the data format for control systems used in the numerical control of machines. Improves the co-ordination of system design in order to minimize the variety of program manuscripts required. Is not intended for use in flame cutting machines and drafting machines used specifically and exclusively in the shipuilding industry.
