ISO 8791-3:2017 specifies a method for the determination of the roughness of paper and board using the Sheffield apparatus. ISO 8791-3:2017 is applicable to papers and boards which have Sheffield roughness values between 10 ml/min and about 3 000 ml/min. It is not suitable for soft papers which allow the lands of the test head to indent the surface, or for high air-permeance papers which allow a…

ISO 7404-4:2017 specifies a method, using a graticule with 20 crossline intersections, for determining the proportions of microlithotypes, carbominerite and minerite in coals. It applies only to determinations made on polished particulate blocks using reflected white light (about 400 nm to 700 nm). Additional blue, blue-violet or UV light excitation (365 nm to 440 nm) for better identification of…

IEC TR 63099-1:2017(E) provides information about the current and latest applications for antenna measurement that use radio-over-fibre technologies. Antenna gain and the antenna radiation pattern measurement system are covered, which are practically in use and will be used soon. Basic concepts, system configurations and measurement examples of the systems are included.

ISO 19155-2:2017 defines the following three mechanisms for linking Place Identifiers (PIs) (see ISO 19155) to features or objects existing in other encodings: - Id attribute of a GML object (gml:id) as defined in ISO 19136; - Universally Unique Identifier (UUID) as defined in IETF RFC 4122; - Uniform Resource Locator (URL) as defined in IETF RFC 1738. These PI linking mechanisms…

The scope of ISO/IEC/IEEE 8802-1AB:2017 is to define a protocol and management elements, suitable for advertising information to stations attached to the same IEEE 802 LAN, for the purpose of populating physical topology and device discovery management information databases. The protocol facilitates the identification of stations connected by IEEE 802 LANs/MANs, their points of interconnection,…

ISO 18504:2017 provides procedures on sustainable remediation. In particular, it provides: - standard methodology, terminology and information about the key components and aspects of sustainable remediation assessment; - informative advice on the assessment of the relative sustainability of alternative remediation strategies. ISO 18504:2017 is intended to inform practitioners about…

1.1 This Code applies to the installation, inspection, repair, and maintenance of the fuel storage and delivery system installed in powered industrial truck applications and vehicles for use with compressed natural gas (CNG). This includes fuel systems on self-propelled vehicles for the provision of motive power. Regulatory requirements might supersede the requirements of this Code. 1.2 This…

IEC 62271-1:2017 applies to AC switchgear and controlgear designed for indoor and/or outdoor installation and for operation at service frequencies up to and including 60 Hz and having rated voltages above 1 000 V. This document applies to all high-voltage switchgear and controlgear except as otherwise specified in the relevant IEC standards for the particular type of switchgear and controlgear…

IEC 60137:2017 specifies the characteristics and tests for insulated bushings. This standard is applicable to bushings, as defined in Clause 3, intended for use in electrical apparatus, machinery, transformers, switchgear and installations for three-phase alternating current systems, having highest voltage for equipment above 1 000 V and power frequencies of 15 Hz up to and including 60 Hz.…
