As a connected standard of ISO 19626-1, this document defines the communication interactions between TCP system components and specifies their detailed interfaces — the processes and the APIs of the TCP system components. It provides the common communication interface for deployment and implementation of the system components, and their functions in a specific technology-neutral way to those who…

IEC TS 63156:2021 describes the procedure for evaluating the energy conversion performance of stand-alone or grid-connected power conversion equipment (PCE) used in PV systems. This procedure includes the calculation of inverter performance to anticipate the energy yield of PV systems. This evaluation method is based on standard power efficiency calculation procedures for PCE found in IEC 61683…

The document specifies test conditions for determining the seasonal performance characteristics of air source heat pump water heaters for space heating with electrically driven compressors with or without supplementary heater. The purpose of this document is to rate performance of the heat pump water heaters for space heating with no operation of any supplementary heater. In the case of heat pump…

This document provides the data and indications necessary for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing deviations and their effects on the fit between connecting coaxial spline elements are defined in the formulae and given in the tables. Unless otherwise specified, linear dimensions are…

This document provides data, guidance and requirements for the inspection of straight (non-helical) side fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing deviations and their effects on the fit between connecting coaxial spline elements are defined and tabulated. Linear dimensions are expressed in millimetres and angular dimensions in degrees.

This document specifies geometry and inspection dimensions for the design and manufacture of straight (non-helical) side-fitting cylindrical involute splines. Limiting dimensions, tolerances, manufacturing errors and their effects on the fit between connecting coaxial spline elements are defined and tabulated. Linear dimensions are expressed in millimetres and angular dimensions in degrees. The…

1 Scope 1.1 This Standard applies to newly-produced torches for use with propane, butane, natural gas, and MPS (methyl acetylene-propadiene stabilized). This Standard applies to torches that aspirate atmospheric air for combustion. 1.2 This Standard applies to hand-held torches intended for industrial applications such as brazing, soldering, pre-heating for welding, heat treatment, and…

1 Scope This clause of Part 1 is applicable, except as follows: Replacement of the third paragraph: The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a. c. tools. Addition: This document applies to transportable wall saws guided by a track guiding system intended for dry cutting or to be connected to a liquid system for cutting concrete…

1 Scope 1.1 This Standard sets forth minimum requirements for emergency breakaway fittings, swivel connectors and pipe-connecting fittings of the threadless compression type. Connectors and fittings covered by these requirements are intended only for the following services. 1.2 A swivel connector is either a hose swivel or swivel joint. The swivel connector will allow radial movement and is…

1 Domaine d’application 1.1 Cette norme établit les exigences minimales pour les raccords à rupture d’urgence, les raccords pivotants et les raccords de tuyau du type à compression sans filetage. Les raccords couverts par les présentes exigences sont destinés uniquement aux services suivants. 1.2 Un raccord pivotant est un raccord tournant ou un joint à rotule. Le connecteur raccord pivotant…
