1Scope

This European Standard applies to self-propelled and pedestrian propelled manual and semi-manual industrial trucks as defined in ISO 5053 including their load handling devices and attachments (hereafter referred to as trucks) intended for use in potentially explosive atmospheres.

NOTE 1Attachments mounted on the load carrier or on fork arms which are removable by the user are not considered to be a part of the truck.

This standard only specifies the technical requirements for the prevention of the ignition of an explosive atmosphere by industrial trucks of equipment group II and equipment category 2G, 3G, 2D or 3D.

NOTE 2 The relationship between an equipment category (hereafter referred to as category) and the corresponding zone is shown in informative Annex B.

This standard does not include:

¾ðtrucks of equipment group I;

¾ðtrucks of equipment group II, equipment category 1;

¾ðtrucks intended for use in potentially explosive atmospheres with hybrid mixtures;

¾ðprotective systems.

This standard is not applicable to trucks intended for use in potentially explosive atmospheres of carbon disulphide (CS2), carbon monoxide (CO) and/or ethylene oxide (C2H4O) due to the special properties of these gases.

This standard is applicable to trucks intended for use in atmospheres with an ambient temperature range of -20 °C to +40 °C, i.e. trucks built in accordance with this standard will be satisfactory to any service conditions within this range unless otherwise specified.

NOTE 3The ambient temperature range -20 °C to +40 °C is in line with EN ISO 3691-1.
