BS EN 14460 specifies requirements for explosion-pressure-resistant and explosion pressure shock-resistant equipment. It is only applicable to equipment made of metallic materials.

Explosion resistance is the term applied to the construction of an enclosure so that it can withstand an expected explosion pressure without rupture. Equipment that is explosion resistant means that the range of explosion flames are limited, and that explosion pressures are limited to a sufficient level of safety.

The equipment property "explosion resistance" can be used for equipment, protective systems and components.

The principles of integrated explosion safety include the specific measures the manufacturer has to take:

Prevention of formation of explosive atmospheres
Prevention of the ignition of the explosive atmospheres
If an explosion nevertheless occurs, to halt it immediately and/or to limit the range of explosion flames
Explosion pressures to a sufficient level of safety.

This standard is applicable to process vessels and systems. It is not applicable to individual items of equipment such as motors and gearboxes that may be designed to withstand an internal explosion, which is the subject of EN 13463-3.

This standard is valid for atmospheres having pressures ranging from 800 hPa to 1100 hPa and temperatures ranging from - 20 °C to + 60 °C. This standard may also be helpful for the design, construction, testing and marking of equipment intended for use in atmospheres outside the validity range stated above, as far as this subject is not covered by specific standards.

This standard applies to equipment and combinations of equipment where deflagrations may occur and is not applicable to equipment and combination of equipment where detonation may occur. This standard should not be used for offshore applications.
