Information technology - Top-level ontologies (TLO) - Part 1: Requirements
This document specifies required characteristics of a domain-neutral top-level ontology (TLO) that can be used in tandem with domain ontologies at lower levels to support data exchange, retrieval, discovery, integration and analysis.
If an ontology is to provide the overarching ontology content that will promote interoperability of domain ontologies and thereby support the design and use of…

This document defines methods for reducing combined samples (or increments) to laboratory samples
and laboratory samples to sub-samples and general analysis samples and is applicable to solid biofuels.
The methods defined in this document can be used for sample preparation, for example, when the
samples are to be tested for calorific value, moisture content, ash content, bulk density…
Solid biofuels — Determination of content of heavy extraneous materials larger than 3,15 mm
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…
Solid biofuels — Simplified sampling method for small scale applications
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…

1.1 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.
Meat and meat products — Determination of total phosphorous content
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…
