It applies to the application of electrical, electronic and programmable electronic equipment and systems to machines not portable by hand while working, including a group of machines working together in a co-ordinated manner.

General requirements for safety.

Glowing/hot-wire based test methods – Glow-wire apparatus and common test procedure
Specifies the glow-wire apparatus and common test procedure to simulate the effect of thermal stresses which may be produced by heat sources such as glowing elements or overleaded resistors, for short periods, in order to assess the fire hazard by a simulation technique. The test described in this standard is applicable to electrotechnical equipment, its subassemblies and components, and may also be applied to solid electrical insulating materials or other solid combustible materials.

Defines measurement methods for d.c. or a.c. of sinusoidal or non-sinusoidal waveform, which could flow through the human body, and current flowing through a protective conductor. The measuring methods recommended for touch current are based upon the possible effects of current flowing through a human body. In this standard, measurements of current through networks representing the impedance of the human body are referred to as measurements of touch current.

Part 2: Test equipment.
Applicable to the test equipment used for dielectric tests on low-voltage equipment. It covers tests with direct, alternating or impulse voltage, impulse current, and tests with a combination of impulse current.

Documentation. Applies to the technical documentaion to be supplied with electrical and electronic measuring equipment for use in laboratories and for testing and servicing.
