Deals with apparatus certified or assessed in accordance with the requirements of type of protection 's'. It does not apply to underground mining, but may be applied to certain surface mining installations. For the purpose of the Standard, explosion risks due to the presence of combustible gases and vapours only are considered.

This Part of the code offers guidance in the selection, installation and maintenance in Class 1 hazardous areas of electrical apparatus which is certified or assessed in accordance with the requirements of Type of Protection 's': Special Protection. (For relevant specifications, see Rule 1.4.) It should be noted that the recommendations of the code do not apply to the underground mining industry, where other precautions are necessary, though it is recognized that the recommendations of the code may be applied to certain parts of the surface mining industries.For the purposes of this Part of the code, explosion risks due to the presence of combustible gases and vapours only are considered. Combustible dusts are therefore excluded, except were otherwise noted (see also Part 10).
