Thermal performance of buildings and building components. Physical quantities and definitions1 Scope This document defines physical quantities used in the thermal performance of buildings and building elements, and gives the corresponding symbols and units. NOTE Because the scope of this document is restricted to thermal performance and energy use in the built environment, some of the definitions it contains differ from those given ISO 80000 5.

which may be connected together either rigidly or by means of a flexible cable

Part 1: Terms common to power

d) Forgings: annealed

Measurements of the crop and basic meteorological conditions at the time of spraying are made as part of the test procedure

All that can be attempted is some control of the conditions under which it is produced

It brings national standards for hot rolled structural sections together into a single European document

The temper designations used in this part are according to BS EN 515

such as a “contact filter”

The average molecular weight and the molecular weight distribution are calculated from a calibration curve constructed using polymer standards if using one of the SEC techniques described in ISO 16014‑2 to ISO 16014‑4 or from a calibration curve constructed using absolute molecular weight data if using size-exclusion chromatography coupled with light-scattering detection (SEC-LS) as described in ISO 16014‑5

which provides a domain- and an implementation-agnostic way to reference the large existing body of knowledge
