Specification of a method for determination of the relative flammability characteristics of small specimens of rigid plastics. Assessment of the flammability after bringing its free end into contact with a silicon carbide rod electrically heated to 955 °C, for a specified period of time. The result is expressed as the average burning time and the average destroyed length.

This International Standard specifies the Position and maximum width dimensions of original variable area and variable density monophonic 35 mm negative photographic Sound records on 35 mm motion-picture film.

Covers pest control chemicals and plant growth regulators of international importance. The standard is presented as a combined English/French text. It gives references to related standards and specifies the principles for the selection of names and the style of writing.

Gives general intructions and specifies the methods for the determination of density at 20 °C, for the determination of boiling range, for the determination of dry residue after evaporation on a water bath, for the measurement of colour, for the determination of water content and of aldehydes and ketones content. International Standards ISO 756/1, ISO 756/2 and ISO 756/3 cancel and replace ISO…

The principle consists in dilution of a test portion with carbon dioxide-free water, titration of the acidity with standard volumetric sodium hydroxide solution, in the presence of phenolphthalein as indicator. The method is applicable to products having an acidity, expressed as acetic acid, equal to or greater than 0,0006 % (m/m).

Lays down two methods for the determination of the total sulphur content in all types of carbon black for use in the rubber industry: Method A, using an oxygen bomb calorimeter; Method B, using a combustion furnace. The total sulphur content, expressed as a percentage by mass, is given by a formula.
