Energy performance of buildings — Energy requirements and efficiencies of heating, cooling and domes...
This document specifies the energy performance calculation of water-based distribution systems for space heating, space cooling and domestic hot water (DHW).
This document is applicable to the heat flux from the distributed water to the space and the auxiliary energy of the related pumps.
The heat flux and the auxiliary energy for pumps can be calculated for any time interval (hour, month and…
Paper, board, pulps and cellulosic nanomaterials — Determination of dry matter content by oven-dryin...
This document specifies an oven-drying method for the determination of the dry matter content in paper, board, pulp and cellulosic nanomaterials in solid form, which all can be produced from virgin and /or recycled materials.
It is also applicable to the determination of the dry matter content of paper and board for recycling.
The procedure is applicable to paper, board, and pulp and cellulosic…
Terrestrial photovoltaic (PV) modules - Design qualification and type approval - Part 1-2: Special r...
IEC 61215-1-2:2021+AMD1:2022 lays down requirements for the design qualification of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. The useful service life of modules so qualified will depend on their design, their environment and the conditions under which they are operated. Test results are not construed as a quantitative prediction of module lifetime.…
