This document specifies the requirements for dimensions, safety and performance of mobile working platforms made of prefabricated elements used as low height and low load capacity temporary work equipment.

This document applies to the design of mobile working platforms:
− with wheels;
− for assembly by one person;
− for use by one or more persons;
− with no more than one platform level;
− made of prefabricated elements with dimensions which are fixed by the design;
− with a platform height limited to 2,0 m;
− with minimum platform dimensions of 0,5 m x 1,0 m and maximum
− platform dimensions of 2,0 m x 3,5 m;
− used indoors or outdoors.

This document does not apply to:
− scaffolds according to EN 12810-1 and EN 12811-1;
− mobile access towers according to EN 1004-1;
− mobile ladders with platform according to EN 131-7;
− ladders with separate platform according to EN 131-8;
− where different load assumptions and verification methods are applied.

This document specifies methods by which the measurement of power (energy) density distribution is made and defines parameters for the characterization of the spatial properties of laser power (energy)density distribution functions at a given plane.
The methods given in this document are intended to be used for the testing and characterization of both continuous wave (cw) and pulsed laser beams used in optics and optical instruments.
This document provides definitions of terms and symbols to be used in referring to power density distribution, as well as requirements for its measurement. For pulsed lasers, the distribution of time-integrated power density (i.e. energy density) is the quantity most often measured.

This document specifies requirements for the design and selection of electrical, mechanical, hydraulic and pneumatic equipment used in all types of cranes and their associated fixed load lifting attachments with the objectives of protecting personnel from hazards affecting their health and safety and of ensuring reliability of function.
NOTE Specific requirements for particular types of cranes, and for load lifting attachments, are given in the appropriate European Standard.
The electrical equipment covered by this document commences at the point of connection of the supply to the crane (the crane supply switch) including systems for power supply and control feeders situated outside the crane, e.g. flexible cables, conductor wires or bars, electric motors and cableless controls.
The principles to be applied for cranes transporting hazardous loads are given in this document. Particular requirements are given for cranes transporting hot molten metal.
This document does not cover the detail design of individual items of equipment except with regard to their selection for specific aspects of use.
The proof of competence calculations and related strength requirements or safety margins of equipment and components are not covered by this document. 
NOTE Some safety margins are given here for issues not covered in the EN 13001 series.
Hazards due to noise are not covered by this document. They are addressed in safety standards specific to each type of crane.
The specific hazards due to potentially explosive atmospheres, ionising radiation, and operation in electromagnetic fields beyond the range of EN 61000-6-2 are not covered by this document.
The significant hazards covered by this document are identified in Annex A.
This document is not applicable to cranes manufactured before the date of its publication.

This document specifies the design and operational characteristics, the safety requirements, test methods and the marking of regulators and automatic change-over devices having a maximum regulated pressure of 4 bar, with a maximum capacity of 150 kg/h, for use with butane, propane and their mixtures in the vapour phase.
The maximum supply pressures for devices covered by this standard are 7,5 bar for butane and 16 bar for propane and LPG.
This document also applies to the safety devices which are included within regulating devices covered by this document.
This document also includes requirements for:
- adaptors for connecting to self-closing valves;
- integral or auxiliary safety devices.
This document covers devices used in locations where the temperature likely to be reached during use is between −20 °C and +50 °C
Additional requirements for devices to be used at temperatures down to −30 °C and/or up to +80 °C are defined in Annex C.
This document gives special requirements for:
- devices intended to be used in caravans and motor caravans (Annex D);
- devices intended to be used in boats (Annex M);
- specific connections which are not defined in other standards (e.g. EN 15202:2019 for cylinder valve connections).
NOTE Boats considered in this document are recreational crafts covered by European Directive 2013/53/EU.

This European Standard covers methods for the calculation of the design heat load for single rooms, building entities and buildings, where the design heat load is defined as the heat supply (power) needed to maintain the required internal design temperature under design external conditions.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 -1.
NOTE 1 In CEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.
