The subdivision is in accordance with !4.2 of EN 13463-1:2001". Trucks marked IIB are suitable for application required for Group IIA trucks. Trucks marked IIC are suitable for application required for subgroup IIA and subgroup IIB trucks, but are not suitable to be used in areas with flammable gas and vapour atmospheres containing carbon disulfide (CS2). Where hybrid mixtures are present, the requirements for gas, vapour and mist as well as for dust shall be fulfilled. Fork arms, load platforms or integrated attachments are part of the truck. Attachments mounted on the load carrier or fork arms are not part of the truck. 2 Normative references !The following referenced documents are indispensable for the application of this document.
