Chemical products for industrial use — General method for determination of chloride ions — Potentiom...
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…
Numerical control of machines — Program format and definition of address words — Part 1: Data format...
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.
Methyl chloride for industrial use — Determination of impurities — Gas chromatographic methods
Specifies a method, the principle of which is based on the analysis of a vaporzed test portion and determination of the contents of impurities. The calibration factors used for this determination are obtained by analysis of external methyl chloride calibration mixtures containing known quantities of the impurities under consederation.
