This document specifies a procedure for the parallel determination of glycidol together with 2-MCPD and 3-MCPD present in bound or free form in oils and fats. The method is based on alkaline-catalysed ester cleavage, transformation of the released glycidol into monobromopropanediol (MBPD) and derivatisation of the derived free diols (MCPD and MBPD) with phenylboronic acid (PBA). Though free MCPD and glycidol are supposed to be present in fats and oils in low to negligible quantities only, in the event that free analytes are present, they would contribute proportionately to the results. The results always being the sum of the free and the bound form of a single analyte.
This method is applicable to solid and liquid fats and oils. This document can also apply to animal fats and used frying oils and fats, but a validation study is undertaken before the analysis of these matrices.
Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this document.

This document specifies a real-time PCR procedure for the quantitation of the amount of equine DNA relative to total mammalian DNA in a raw meat sample.
Results of this equine assay are expressed in terms of equine (Equus genus) haploid genome copy numbers relative to total mammalian haploid genome copy numbers. This assay is specific for representatives of the genus Equus and therefore detects horse, mule, donkey and zebra DNA.
The method has been previously validated in a collaborative study and applied to DNA extracted from samples that consist of raw horse meat in a raw beef (meat) background.
The limit of detection has been determined experimentally to be at least 17 horse haploid genome equivalents (HGE) for both the equine PCR and the mammalian PCR based on the lowest dilution on the respective calibration curves through single laboratory validation. The lowest relative horse content of the target sequence included in the collaborative study was a mass fraction of 0,1 % based on gravimetrically prepared raw horse muscle tissue in a raw beef muscle tissue background.
The compliance assessment process is not part of this document.

—     the pressure loss in the inlet and outlet lines of pressure relief valves and other pressure relief devices and includes the necessary data.
This document specifies the requirements for selection of pressure relief devices to prevent excessive pressure due to internal and external heat sources, the sources of increasing pressure (e.g. compressor, heaters, etc.) and thermal expansion of trapped liquid.
NOTE            The term "refrigerating system" used in this document includes heat pumps.

This document specifies general requirements for non-active surgical implants, hereafter referred to as implants.
This document is not applicable to dental implants, dental restorative materials, transendodontic and transradicular implants, intra-ocular lenses and implants utilizing viable animal or human tissue.
With regard to safety, this document specifies requirements for intended performance, design attributes, materials, design evaluation, manufacture, sterilization, packaging and information supplied by the manufacturer, and tests to demonstrate compliance with these requirements.
Additional requirements applicable to specific implants or implant families are given or referred to in Level 2 and Level 3 standards.
NOTE 1        This document does not require that the manufacturer have a quality management system in place. However, many regulatory authorities require the application of a quality management system, such as that described in ISO 13485, to ensure that the implant achieves its intended performance and safety.
NOTE 2        In this document, when not otherwise specified, the term "implant" refers to each individual component of a system or a modular implant, provided separately or as a set of components, as well as to all ancillary implants or associated implants designed for improving the intended performance.

This document specifies requirements and a test method for migration of bisphenol A from toy materials. This document is applicable to toys intended for use by children under 36 months or other toys intended to be placed in the mouth.
NOTE   The European Commission Guidance Document No 11 on the Application of Directive 2009/48/EC on the Safety of Toys [3] provides guidelines to help on the classification of toys intended for children under 36 months of age or of 36 months and over.

This document defines the procedures as well as the means to implement adequate lighting, with regard to the exhibition lighting and the conservation policy. This also includes security and cleaning lighting. It takes visual, exhibition and conservation aspects into account and it also discusses the implications of the lighting design on the safeguarding of cultural heritage. This document gives recommendations on luminous exposure values. It aims to provide a tool for setting up a common European policy and a guide to help curators, conservators and project managers to assess the correct lighting that can ensure the safeguarding of the objects. This document covers indoor lighting for heritage objects on exhibition in both public and private sites and does not consider lighting in other cultural heritage contexts such as open-air collections, etc.
This document does not cover non-public activities such as conservation-restoration, storage, emergency lighting and research.

This document specifies requirements and test methods for determining the concentration of phenol in aqueous toy materials and for migration of phenol from polymeric toy materials. This document is applicable to toys intended for use by children under 36 months or other toys intended to be placed in the mouth.
NOTE   The European Commission Guidance Document No 11 on the Application of Directive 2009/48/EC on the Safety of Toys [4] provides guidelines to help on the classification of toys intended for children under 36 months of age or of 36 months and over.

This document specifies methods for the reduction and preparation of samples of fertilizers, liming materials, inhibitors and blends and sets out the requirements for sample preparation reports. It also specifies methods for the preparation of test samples and test portions from laboratory samples of fertilizer for subsequent chemical or physical analysis. It does not cover the preparation of samples for certain physical tests which require test portions of more than 2 kg.
NOTE 1   The term “fertilizer” is used throughout the body of this document and is understood to include liming materials and inhibitors unless otherwise indicated.
NOTE 2   In relation to the procedures set out in this part of the standard any special procedures specific to a particular test method will be set out in that method standard.

This document specifies the requirements relating to:
Steel 15CrMoV6 (1.7334)
Air melted
Hardened and tempered
Bars for machining
De ≤ 100 mm
1 080 MPa ≤ Rm ≤ 1 250 MPa
for aerospace applications.
