Liquids simulating fodd and beverages are placed in contact with mouldings of the sample material, under defined conditions. The formaldehyde content of the liquid is then determined and the quantity of formaldehyde extracted per unit area of content is calculated. Two spectrophotometric methods for the determination of formaldehyde in the liquid, using chromotropic acid disodium salt or…

1. Scope 1.1 This Standard provides minimum requirements for mineral fibre, for use primarily in the insulation of dwellings and other heated building structures, and defines the types in current use. This Standard does not apply to preformed insulation less than 40 mm in thickness.

Is intended for the general application to cylindrical shafts and shafts ends, and gives the relationship which should be observed between the diameter of shaft and the section of key. Steel with a tensile strength of 590 N/mm is defined as the material to be used.

Gives a classification of various types of compressors and some definitions. a list of equivalent English and French terms relating to some of the types is given in an annex, together with explanatory diagramms. Applies to compressors defined as machines for the displacement and compression of gaseous media for any pressure values, with the exeption of fans and vacuum pumps.
