Builders hoists for persons and materials with vertically guided cages1 Scope 1. 1 This European Standard deals with power operated temporarily installed builders hoists (referred to as "hoists" in this standard) intended for use by persons who are permitted to enter sites of engineering and construction, serving landing levels, having a cage: designed for the transportation of persons or of persons and materials; guided; travelling vertically or along a path within 15 max. of the vertical; supported or sustained by

filled transport package or unit load using a variable frequency

which can be expelled by the action of internal pressure and are intended to extinguish test fires of type A + B

This part of IEC 62600 defines the terms relevant to marine energy

ISO 8820‑8 provides the tests and requirements on the fuse-links to ensure voltage drop

In particular it applies to connections for pipelines and Venturi attachments

testing and certification (qualification and/or homologation)

and the determination of the effective load capacitance CLeff at the nominal frequency for crystals with the figure of merit M > 4

Heating and ventilating installations

energy efficiency at constant power level which allows you to enhance the performance and energy output of flow battery energy system

ISO 22137 on space systems is applicable to:

It enables applications to be built which use the interoperable ISLI system for the identification of links

BS 4401-2 provides you with guidance on apparatus
