Classifies in four categories the different kinds which can be defined in terms of the nature of the fuel. These classes are useful in the context of fire-fighting by means of an extinguisher.
Signs and Symbols for the Occupational Environment
Applies to signs for use in the occupational environment. It
describes requirements for the shape and colour of signs and sets
down a classification system, defined so as to assist the user in
determining what signage is needed. The standard also includes
requirements for glyphs which may be used with or without
legends, subject to the limitations of the standard, to describe
a specific…
Information interchange - Representation of human sexes
A uniform representation of human sexes for information interchange is defined. Is intended to - reduce time for recording and formatting representation of sexes and transmit them; improve clarity and accuracy of interchange; minimize amoung of human intervention for communicating the representation of sexes; reduce costs. Meets requirements of most applications needing to code human sexes.…

Measurement of gas flow in conduits — Tracer methods — Part 1: General
Applies to flow measurement in conduits into which a tracer can be injected in such a way that effective mixing in single phase with the gas flowing in the pipe can be achieved. The fluid in the conduit can be a mixture of several gases provided the thermodynamic state and conditions of flow of this mixture are well defined.
Geometrical orientation and directions of movements
Establishes and defines directional terms in stationary cirmumstances. Is a fundamental document to be used when drawing up other documents where the quantities concerned plays a rule.
Procedure for Measurement of the Maximum Exterior Sound Level of Stationary
Trucks with Governed D...
1. Scope
1.1 This Standard applies to trucks designed primarily for use on the road
and defines a procedure for measuring the maximum exterior sound level
emitted by trucks with governed diesel engines. The measurement is
made with the vehicle stationary and with the transmission in neutral.
1.2 The procedure defined in this Standard is primarily intended…
Plastics — Melamine-formaldehyde mouldings — Determination of extractable formaldehyde
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.
