1 Scope This document specifies a method for the determination of content of heavy extraneous materials larger than 3,15 mm by the use of sink-and-float separation combined with elutriation. This document is applicable to woody biomass in accordance with ISO 17225-1:2014, Table 1. NOTE 1 This method is designed to determine the level of impurities larger than 3,15 mm top size with a specific…

1 Scope This document describes simplified methods for taking samples of solid biofuels in small scale applications and storages including preparation of sampling plans and reports. The main focus is on storages with a size of =100 t. This document is applicable to the following solid biofuels: 1) fine (up to about 10 mm nominal top size) and regularly-shaped particulate materials that can be…

1 Scope 1.1 General This Standard applies to packages for consumer products available in liquid or solid form that incorporate reclosable child-resistant features that restrict children’s ability to gain access to the contents of the packages. Such packages include (but are not limited to) packages with a continuous- thread, lug-finish, or snap closure. 1.2 Requirements This Standard includes…

This document specifies an acid digestion and vapour generation atomic absorption spectrometric method for the determination of the mercury content in copper sulfide concentrates. This document is applicable to mass fraction of mercury between 5 µg/g and 65 µg/g in copper sulfide concentrates.

This document specifies three methods for the determination of the total phosphorous content of all kinds of meat and meat products, including poultry and livestock: the inductively coupled plasma optical emission spectrometry (ICP-OES) method; the spectrometric method; the gravimetric method. For the ICP-OES method, the limit of detection (LOD) is 1,0 mg/kg and the limit of quantification (LOQ…

IEC 62841-3-12:2017+A1:2021 applies to transportable threading machines. 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. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in Annex K. This standard deals with the hazards presented by tools which are encountered…

IEC 60255-187-1:2021 specifies the minimum requirements for functional and performance evaluation of (longitudinal) differential protection designed for the detection of faults in ac motors, generators and transformers. This document also defines how to document and publish performance test results. This document defines the influencing factors that affect the accuracy under steady state…

This document defines the LTFS Format requirements for interchanged media that claims LTFS compliance. Those requirements are specified as the size and sequence of data blocks and file marks on the media, the content and form of special data constructs (the LTFS Label and LTFS Index), and the content of the partition labels and use of MAM parameters. The data content (not the physical media) of…

IEC 62271-101:2021 mainly applies to AC circuit-breakers within the scope of IEC 62271-100. It provides the general rules for testing AC circuit-breakers, for making and breaking capacities over the range of test duties described in 7.102 to 7.111 of IEC 62271-100:2021, by synthetic methods. It has been proven that synthetic testing is an economical and technically correct way to test high-…
