This part of ISO3691 gives safety requirements and the means for their verification for the following types of self-propelled industrial trucks (hereafter referred to as trucks), as defined in ISO5053 : industrial counterbalanced trucks; reach trucks with retractable mast or retractable fork arm carriage; straddle trucks; pallet-stacking trucks; high-lift platform trucks; trucks with elevating operator position up to 1200mm; side-loading trucks (one side only); lateral-stacking trucks (both sides), and lateral- and front-stacking trucks; pallet trucks; bidirectional and multidirectional trucks; tractors with a drawbar pull up to and including 20000N; rough-terrain counterbalanced trucks; industrial trucks powered by battery, diesel, gasoline or LPG (liquefied petroleum gas). NOTE1 Trucks powered by CNG (compressed natural gas) are not dealt with. It is intended that CNG and other power sources be addressed in future revisions of this part of ISO3691 . For trucks with an elevating operator position of more than 1200mm and/or trucks designed to travel with an elevated load of more than 1200mm, this part of ISO3691 is intended to be used in conjunction with ISO3691‑3 . NOTE2 ISO3691‑3 is not applicable to counterbalanced fork lift trucks or trucks intended for container handling. NOTE3 Some low-level order pickers with an elevating operator\'s position up to and including 1200mm lift height can be equipped with an additional lifting device to lift the load to a maximum lift height of 1800mm. This part of ISO3691 is not applicable to self-propelled variable-reach trucks, driverless trucks or burden carriers, which are covered in ISO3691‑2 , ISO3691‑4 and ISO3691‑6 , respectively. It is not applicable to industrial trucks operating in severe conditions (e.g. extreme climates, freezer applications, hazardous environments), where special precautions can be necessary. Regional requirements, additional to the requirements given in this part of ISO3691 , are addressed in ISO/TS3691‑7 and ISO/TS3691‑8 . This part of ISO3691 deals with all significant hazards, hazardous situations or hazardous events, as listed in AnnexB, with the exception of the following, relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It does not establish requirements for hazards that can occur during construction, when handling suspended loads that can swing freely, when using trucks on public roads, when operating in potentially explosive atmospheres, when using trucks in very narrow aisles with clearance of less than 500mm to the racks, arising from a non-ergonomic body attitude when driving sit-on trucks, load trailing, during travelling with unladen trucks having a rated capacity of more than 10000kg, due to visibility concerns, due to overload. NOTE4 For the purposes of this part of ISO3691 , fork arms, load platforms and integrated attachments are considered to be parts of the industrial truck. Attachments mounted on the load carrier or on the fork arms which are removable by the user are not considered to be part of the industrial truck. Requirements for attachments are given in the appropriate clauses.
