Paper and board — Determination of titanium dioxide content
Specifies a method for determining titanium dioxide content in all kinds of paper and board, in particular coated or filled products. It comprises two procedures for the final determination of titanium based on spectrophotometry and flame atomic absorption spectrophotometry, respectively. The limits of determination depend on the amount of sample taken. Titanium present in other forms will not…
Soft soldering fluxes — Test methods — Part 1: Determination of non-volatile matter, gravimetric met...
Specifies a gravimetric method for the determination of the content of non-volatile matter in soft soldering fluxes. Applies to liquid and paste fluxes of type 1, as defined in ISO 9454-1.
Information technology — Guidelines for the management of software documentation
Addresses the policies, standards, procedures, resources and plans to produce an effective software. Applicable to all types of software from the simplest program to the most complex software system and to all stages of the software lifecycle. Detailed advice on the content and layout of software documentation is not provided. Annex A contains checklists of the policies, standards, procedures and…
Gives guidance on the contents and the presentation of a crane driving manual which include: technical data, special safety advice, driver's aids and controls, driver's instructions, load diagrams and load tables, safety devices, environmental conditions.
Rubber — Determination of styrene content — Nitration method
Applicable to all types of styrene-butadiene rubber (SBR) including oil-extended types and also for block copolymers containing up to 50 % (m/m) of styrene. The procedure may give low results when the content of mineral fillers insoluble in nitric acid exceeds 5 % (m/m). The principle is based on the extraction of a test portion with acetone and digestion with nitric acid to oxidize the styrene…

Rubber, raw, natural — Determination of castor oil content — Part 2: Determination of total ricinole...
Applicable to all grades of natural rubber. The principle is based on extraction of any free ricinoleic acid and conversion to the acetate of methyl ricinoleate. Extraction of any castor oil glycerides also present, hydrolysis to ricinoleic acid, and conversion to the corresponding acetate of methyl ricinoleate. Determination of the total acetate by gas chromatography by comparison either with a…
Sound system equipment. Part 17: Standard volume indicators
Gives the characteristics to be specified, performance requirements and the relevant methods of measurement for electromechanical volume indicators. The concept of 'volume' is a practical way of assigning a numerical value to the magnitude of electrical speech and music programme signals. The contents of the corrigendum of September 1991 have been included in this copy.
