Primary and secondary function motors (see Clause 4) are covered in this document; however,…
Uncertainty of measurement — Part 6: Developing and using measurement models
This document provides guidance on developing and using a measurement model and also covers the assessment of the adequacy of a measurement model. The document is of particular interest to developers of measurement procedures, working instructions and documentary standards. The model describes the relationship between the output quantity (the measurand) and the input quantities known to be…
Terrestrial photovoltaic (PV) modules - Design qualification and type approval - Part 1-2: Special r...
IEC 61215-1-2:2021 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. This…
