Thermosyphon foundations for buildings in permafrost regions
1 Scope, objectives, and application
1.1 Scope
This Standard provides requirements for all life cycle phases of thermosyphon foundations for new
buildings on permafrost, including site characterization, design, installation, and commissioning phases
as well as for monitoring and maintenance phases. This Standard is meant to ensure the long-term
performance of thermosyphon-supported…
1 Scope
1.1
This Standard provides requirements, recommendations, and guidance for understanding the potential risks to biomass supply chains, including the following risk categories and associated risk factors:
a)
supplier risk (including credit-worthiness/problematic future solvency of supplier; supplier contracts; supply inventory; conflicts of interest/vested interest with competing…
Solid biofuels — Determination of moisture content — Oven dry method — Part 2: Total moisture — Simp...
1 Scope
This document describes the method of determining the total moisture content of a test sample of solid
biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine
production control on site. The method described in ISO 18134 (all parts) is applicable to all solid
biofuels. The moisture content of solid biofuels (as received) is always reported…
Moderating the effects of permafrost degradation on existing building foundations
1 Scope
1.1 Mitigation strategies and other actions

a)
site techniques that consist of
i)
site grading and drainage;
ii)
snow management; and
iii)
shading or albedo change.
b)
foundation techniques that consist of
i)
ventilation;
ii)…

Explosive atmospheres - Part 10-1: Classification of areas - Explosive gas atmospheres
IEC 60079-10-1:2020 is concerned with the classification of areas where flammable gas or vapour hazards may arise and may then be used as a basis to support the proper design, construction, operation and maintenance of equipment for use in hazardous areas.
It is intended to be applied where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air, but it…
Explosive atmospheres - Part 10-1: Classification of areas - Explosive gas atmospheres
IEC 60079-10-1:2020 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60079-10-1:2020 edition 3.0 and the previous IEC 60079-10-1:2015 edition 2.0. Futhermore, comments from IEC SC 31J experts are provided to explain the reasons of the most relevant changes. The contents of the…
Electric vehicle conductive charging system - Part 25: DC EV supply equipment where protection relie...
IEC 61851-25:2020 applies to the DC EV supply equipment for charging electric road vehicles with a rated supply voltage of up to 480 V AC or up to 600 V DC, with rated output voltage not exceeding 120 V DC and output currents not exceeding 100 A DC.
This document provides the requirements for the DC EV supply equipment where the secondary circuit is protected from the primary circuit by…
