Steel structures — Part 2: Fabrication and erection
This part of ISO 10721 specifies the requirements for the fabrication, erection and inspection of structural steelwork
in buildings designed in accordance with ISO 10721-1, including steelwork in composite steel and concrete
structures.
This part of ISO 10721 is also applicable to bridges, off-shore and other civil engineering and related structures, but
for such structures it may be necessary to…
Low-voltage switchgear and controlgear - Part 1: General rules
1 General
The purpose of this standard is to harmonize as far as practicable all rules
and requirements of a general nature applicable to low-voltage switchgear and
controlgear in order to obtain uniformity of requirements and tests throughout
the corresponding range of equipment and to avoid the need for testing to
different standards.
All those parts of the various equipment standards…
