This document specifies the test methods for discrete polymer fibre for fibre-reinforced cementitious composites (FRCC). This document defines the test methods for discrete polymer fibre, such as diameter, length, tensile strength, initial modulus of elasticity, density, melting point, moisture content and alkaline durability as basic items. These are test methods intended for certification of a…

The ALERT-C protocol is designed to provide mostly event-oriented road end-user information messages. This document specifies the messages which are presented to the user in accordance with a set of general requirements. It defines the message structure and content and its presentation to the end-user. The message management component of this document describes the message management functions…

This document provides a methodology for undertaking a water loss investigation and establishing general principles for water loss management in drinking water distribution networks in order to improve the sustainability of drinking water utilities and protect the environment by saving water, energy and use of chemicals. This document establishes a procedure to estimate water loss components…

This document specifies a global transport data management (GTDM) framework composed of — global transport basic data model, — global transport access control data model, — global transport function monitor data model, and — sensor and control network data model to support data exchange between applications. This document defines standardized data classes in a Global Transport…

IEC 61000-4-30:2015+A1:2021 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method's implementation. This standard addresses…
