This International Standard provides principles derived from the application of anthropometric data to the design of workstations. It is based on ergonomics and currently available anthropometric measurements.

This International Standard specifies the body's space requirements for normal operation of equipment in sitting, sit-standing and standing positions. It includes space demands for maintenance, repairing and cleaning work.

This International Standard does not give recommendations specifically for visual display terminal workstations at machinery. For this purpose, ISO 9241-5 can be used in conjunction with this International Standard.

Safety distances intended to prevent hazard zones being reached by upper and lower limbs are provided in ISO 13857.

This document specifies laboratory test procedures to determine a high-frequency dynamic stiffness, "acoustic stiffness", of resilient components. The purpose is to provide data for assessment and specification of the acoustic performance of track components.

This document is applicable to complete track fastening assemblies and to pad components of fastening systems including both discrete and continuous fastening systems.

It is applicable to specimens of a single rail seat fastener.

It is applicable to the measurement of the dynamic transfer stiffness under a prescribed pre-load and the associated hysteretic damping loss factor.

It provides measurement methods and pre-load, excitation and frequency range conditions for application to ground borne and structure borne noise as well as for rolling noise.

It is not applicable to the measurement of the stiffness of pads and fastening assemblies under static or low frequency dynamic loading used for track mechanics and which is specified in EN 13146-9.

This European Standard is to be used together with EN 13001-1, EN 13001-2 and EN 13001-3-1 as well as pertinent crane type product EN standards, and as such they specify general conditions, requirements and methods to, by design and theoretical verification, prevent mechanical hazards of hydraulic cylinders that are part of the load carrying structures of cranes. Hydraulic piping, hoses and connectors used with the cylinders, as well as cylinders made from other material than carbon steel, are not within the scope of this standard.

The following are significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse. Clauses 4 to 7 of this standard are necessary to reduce or eliminate risks associated with the following hazards:

a) exceeding the limits of strength (yield, ultimate, fatigue);

b) elastic instability (column buckling).

NOTE EN 13001–3–6 deals only with the limit state method in accordance with EN 13001–1.

This part of ISO 3691 gives safety requirements and the means for their verification for self-propelled carriers designed for carrying burdens without lifting, as defined in ISO 5053, and/or personnel carriers, having three or more wheels, a maximum speed not exceeding 56 km/h and a load capacity not exceeding 5 000 kg (hereafter referred to as carriers or trucks).

This part of ISO 3691 is applicable to trucks equipped with a platform (which can be tilting) for the purpose of carrying materials or with a number of seats for the purpose of transporting passengers.

It is not applicable to
— vehicles intended primarily for earth-moving or over-the-road hauling,
— driverless trucks,
— golf cars,
— tractors with a drawbar pull up to and including 20 000 N equipped with a platform for the purpose of carrying materials.

This part of ISO 3691 deals with all significant hazards, hazardous situations or hazardous events, as listed in Annex A, 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 when using trucks on public roads or when operating in potentially explosive atmospheres.

Regional requirements, additional to the requirements given in this part of ISO 3691, are addressed in ISO/TS 3691-7 and ISO/TS 3691-8.
