This document illustrates the formulae and templates necessary to calculate the various pipe properties given in International Standards, including — pipe performance properties, such as axial strength, internal pressure resistance and collapse resistance, — minimum physical properties, — product assembly force (torque), — product test pressures, —…

IEC 60051-3:2018 applies to direct acting indicating wattmeters and varmeters having an analogue display. IEC 60051-3:2018 also applies to: • non-interchangeable accessories (as defined in 3.1.23 of IEC 60051-1:2016) used with wattmeters and varmeters; • a combination of the instruments and the accessories provided that the adjustments have been made for the combination; • direct…

IEC 60051-4:2018 applies to direct acting indicating analogue frequency meters of the following types: • pointer-type frequency meters (as defined in 3.2.11 of IEC 60051-1:2016); • vibrating-reed frequency meters (as defined in 3.2.12 of IEC 60051-1:2016). IEC 60051-4:2018 also applies to non-interchangeable accessories (as defined in 3.1.23 of IEC 60051-1:2016) used with frequency…

IEC 61853-3:2018 describes the calculation of PV module energy rating values. The purpose of this document is to define a methodology to determine the PV module energy output (watt-hours), and the climatic specific energy rating (dimensionless) for a complete year at maximum power operation for the reference climatic profile(s) given in IEC 61853-4. It is applied to determine a specific module…

This document describes test methods for determining the conformance of security crypto suites with the specifications given in ISO/IEC 29167‑19. This document contains conformance tests for all mandatory and optional functions. The conformance parameters are the following: — parameters that apply directly, affecting system functionality and inter-operability; — protocol…

The ISO 17572 series specifies LRMs that describe locations in the context of geographic databases and are used to locate transport-related phenomena in an encoder system as well as in the decoder side. The ISO 17572 series defines what is meant by such objects and describes the reference in detail, including whether or not components of the reference are mandatory or optional, and their…

IEC TS 62876-2-1:2018 establishes a general stability testing programme to verify the stability of the performance of nanomaterials and nano-enabled photovoltaic devices (NePV) devices. These devices are used as subassemblies for the fabrication of photovoltaic modules through a combination with other components. This testing programme defines standardized degradation conditions, methodologies…

This document specifies minimum requirements on the optical effects and the mechanical, chemical and environmental properties of neutral beam splitter coatings. This document applies to neutral beam splitter coatings for optical applications. Thereby the user is able to rely on defined numerical data while the manufacturer of thin films has the choice for the materials and production method.

This document describes the flash method for the determination of thermal diffusivity of ceramic matrix composites with continuous fibre reinforcement. In order to conform with the unidimensional heat transfer hypothesis, the experimental conditions are defined such that the material behaves in a homogeneous manner. This involves performing tests in one symmetry axis of the composite. The method…
