Over deze norm
NEN-EN-ISO 3691 gives safety requirements and the means for their verification for the following types of pedestrian-propelled trucks (hereafter referred to as trucks), equipped with load-handling devices for normal industrial duties, e.g. fork arms and platforms, or integrated attachments for special applications: - pedestrian-propelled straddle stackers, - pallet stackers, - industrial trucks with capacities not exceeding 1 000 kg with manual or electrical battery-powered lifting, - low-lift pallet trucks with lift height up to 300 mm and rated capacity up to 2 300 kg, - scissor-lift pallet trucks with lift heights up to 1 000 mm or rated capacity up to 1 000 kg with manual or electrical battery-powered lifting. It is applicable to trucks provided with either manual or electrical battery-powered lifting, operating on smooth, level, hard surfaces. This part of ISO 3691 deals with significant hazards, hazardous situations and events relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex C). It does not establish the additional requirements for a) climatic conditions, b) operation in severe conditions (e.g. extreme environmental conditions such as freezer applications, high temperatures, corrosive environments, strong magnetic fields), c) electromagnetic compatibility (emission/immunity), d) handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/alkalis, radiating materials, especially brittle loads), e) handling suspended loads which may swing freely handling, f) use on public roads, g) direct contact with foodstuffs, h) operation on gradients or on surfaces other than smooth, level, hard surfaces, i) lifting systems using belts, j) lifting of persons, k) trucks with overturning moment greater than 40 000 Nm, l) scissor-lift trucks whose lifting is powered by external means (electric, pneumatic), m) roll containers, n) trucks that are intended to be towed by powered vehicles, o) trucks designed for special applications (e.g. hospitals, restaurant trolleys), p) winch-operated trucks, q) mobile lifting tables. Hazards relevant to noise, vibration and visibility are not significant and are not dealt with in this part of ISO 3691. Regional requirements, additional to those given in this part of ISO 3691, are addressed in ISO/TS 3691- 7.
