Machine tools — Presentation of lubrication instructions
This International Standard gives guidance to both manufacturers and users of machine tools on the information that should be provided and followed regarding the lubrication instructions.
Higher alcohols for industrial use — Methods of test — Part 2: Determination of acidity to phenolpht...
Relates to C6 to C13 alcohols. The principle consists in titration of a test portion with standard volumetric sodium hydroxide solution, in ethanolic, using phenolphthalein as indicator. The result is expressed in milliequivalents per kilogram. Alternatively, the acidity may also be expressed in terms of the acid value.
Higher alcohols for industrial use — Methods of test — Part 3: Determination of carbonyl compounds c...
Relates to C6 to C13 alcohols. The principle bases on reaction of carbonyl compounds present in a test portion with hydroxylammonium chloride to from an oxime, and potentiometric titration of the hydrochloric acid liberated with standard volumetric ethanolic potassium hydroxide solution.
Higher alcohols for industrial use — Methods of test — Part 4: Determination of bromine number — Tit...
Relates to C6 to C13 alcohols. The principle of the method consists in titration of test portion with standard volumetric potassium bromide/bromate solution in the presence of methyl orange as indicator.
Textile machinery and accessories — Weft pirns for automatic looms
The dimensions of weft pirns for automatic looms are specified. The dimensions shall be as shown in the tables (table 1: Dimensions - dimensions in national standards may lie anywhere within the indicated range -; table 2: Length and diameters). Dimensions of the pirn tip shall be as given in ISO 1131.
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
Specifies a volumetric method, after distillation, for determining of neutral oils, and a titrimetric method, after distillation, for determining of pyridine bases. The principle is based on distillation from an aqueous alkaline solution of a test portion. Measurement of the volume of neutral oils collected. Titration of the bases present in the aqueous distillate and in the oils with standard…
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
Simple empirical test of no great precision. The principle consists in shaking a test portion with sodium hydroxide solution under specified conditions and assessment of any insoluble matter present in suspension in the mixture by comparison either with an agreed standard turbidimetric solution or with sodium hydroxide solution. The comparison of the turbidity of the two solutions is carried out…
