Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes, f...
This document describes a method with two procedures for the assessment of carbon black or pigment particle and agglomerate size, and the rating of dispersion in polyolefin pipes, fittings and compounds.
The method is applicable to polyolefin pipes and fittings, as well as raw material in pellet form, with the choice of procedure to be determined by the referring specification.
The method is…
Telecontrol equipment and systems - Part 5-7: Transmission protocols - Security extensions to IEC 60...
IEC TS 60870-5-7:2025, which is a technical specification, describes messages and data formats for implementing IEC 62351-5:2023 for secure communication as an extension to IEC 60870-5-101 and IEC 60870-5-104.
The purpose of this document is to permit the receiver of any IEC 60870-5-101/-104 Application Protocol Data Unit (APDU) to verify that the APDU was transmitted by an authorized user and…
This document specifies a method for determining the bulk density of solid biofuels using a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described.
Bulk density is not an absolute value;…
Biocombustibles solides — Détermination de la masse volumique apparente
Le présent document spécifie une méthode pour déterminer la masse volumique apparente des biocombustibles solides à l’aide d’un récipient-mesure normalisé. Cette méthode s’applique à tout biocombustible solide versable dont la dimension nominale est inférieure ou égale à 63 mm, tandis que la longueur des particules est inférieure ou égale à 200 mm. Pour les combustibles dont la dimension nominale…
