Describes the basic characteristics of the process of fire development, and gives information based on differentiated temperature-time-curves and on an empirical time of fire duration.

Specifies the dimensional requirements necessary for mounting and interchangeability of nozzle holders. Some figures illustrate shapes, dimensions and tolerances, and reference quantities of concern. The location of the fuel inlet and leak-off connections are not defined, because they vary according to the particular application.

The requirements deal with the geometric charateristics to ensure interchangeability. The dimensions of the joint-ground zone and the outer diameter of the tube connected to the joint are given in a table and illustrated in a drawing. In addition the surface finish is specified. A system of gauges (stell balls) for testing the ball cup is tabled. In the annex a method of testing the leakage…

Specifies the dimensions of the stillages in direct contact with the hand-operated elevating trucks: free height, minimum free width.

Deals with essential dimensions to ensure mechanical interchangeability recommended dimensions, wiring connections to contacts of plug and socket, and marking of contacts of plug and socket.
