3M Cable Accessories In Relation To The ATEX 94/9/EC DirectiveATEX Cold Shrink

The ATEX Directive covers a large range of electrical equipment, potentially including equipment used on fixed offshore platforms, in petrochemical plants, mines, flourmills and other areas where a potentially explosive atmosphere may be present – commonly referrred to as “hazardous areas” and categorised by Zone (Zone 0, 1 or 2) according to the degree of explosion risk.

In very broad terms, there are 3 pre-conditions for the ATEX Directive to apply to the equipment:

a) must have its own source of ignition
b) be intended for use in a potentially explosive atmosphere (air mixtures); and
c) be under normal atmospheric conditions

When used as directed, Cold Shrink cable accessories do not have a source of ignition – they are installed “cold” without requirement for “naked flames or hot-work permit applications for safe jointing, termination and abandonment of LV MV HV cables in hazardous area locations.

The firing of an explosive atmosphere may be caused by a short circuit, but when
installed according to 3M Electrical instructions, these products are safe against short circuits.

To conclude, 3M Cold Shrink cable accessories are not within the scope of the ATEX directive.


Cold Shrink cable accessories are not covered or categorised according to ATEX or any other notified body – they are effectively “non-sparking” and when installed in accordance with the manufacturers installation instructions, in this case 3M Electrical, do not pose a potential explosion risk.

In this instance, a “Statement of Exclusion” applies to cable accessories with respect to the ATEX Directive.
