This document gives guidance on the labelling and information folder of potentially permanent magnet containing products in the context of information exchange between supply chain actors to improve recyclability of permanent magnets.
This document can be used by any natural or legal person that will place into the EU market products containing permanent magnets. The document is horizontal by nature and can potentially be applied to any type of permanent magnet containing product. Explicitly in scope are the product- and component groups mentioned in the introduction, as soon the total mass of permanent magnets is above the reporting level threshold specified 4.1 of this document.
The document specifies:
1.   the graphical format, application, and location of the labels, so they are easily located, legible, and scannable in the end-of-life state of the products in a way that is suitable for products of different sizes and complexity;
2.   the specifications of the data carrier, both in its physical format as placed on the product, and the accessibility, security, and verifiability of information;
3.   the access rights of relevant stakeholders to information;
4.   the information to be supplied regarding the location and composition of the permanent magnets;
5.   the information to be supplied regarding adjacent materials like coatings and fixation features, including adhesives;
6.   how to create step-by-step instructions for accessing and safely removing the permanent magnets, specifying the tools and technologies required, providing the recyclers a practically useful, unequivocal guide on how the disassembly of the magnets can be done most efficiently, and
7.   the format of the data to be supplied as per the previous points 4. – 6.
Labelling is employed for products which encompass at least one component mentioned above or a singular magnet, including segmented magnets, which holds a total mass of magnetic material as described in Table 1. Other magnet-holding components within a product that fall below that threshold are exempt from declaration and labelling. The purpose of these thresholds is to establish a sensible balance between the efforts required by both the responsible entities for labelling, as well as the efforts by the dismantlers and recyclers, and the output of recycled material. By excluding potential scrap sources where the yield would not warrant the effort, the work can be simplified for both sides.

There are numerous pathways to produce hydrogen. This document specifies a methodology for different hydrogen production pathways for determining the greenhouse gases (GHG) emissions associated with the hydrogen supply chain from the raw material extraction up to the production gate.
This document considers the GHG emissions associated with hydrogen production up to the production gate. This document applies to and includes every step within the production process up to the production gate (see Figure 2 in the Introduction).
NOTE            Complementary documents in the ISO 19870 series will consider hydrogen conditioning, conversion and transport methods.
ISO 14044 requires the goal and scope of a life cycle assessment (LCA) be clearly defined and be consistent with the intended application. Due to the iterative nature of LCAs, it is possible that the LCA scope needs to be refined during the study. According to ISO 14040:2006, A.2, the goals and scope of LCAs correspond to one of the following two approaches:
an approach that assigns elementary flows and potential environmental impacts to a specific product system, typically as an account of the history of the product (see 4.1.2);
an approach that studies the environmental consequences of possible (future) changes between alternative product systems (see 4.1.3).
In this document, approach a) is referred to as an attributional approach, while approach b) is referred to as a consequential approach. Complementary information is accessible in the ILCD handbook[4].
A carbon footprint of a product (CFP) (3.1.2) or partial CFP (3.1.3) as defined by ISO 14067 can be estimated using either the attributional or the consequential approach, the latter corresponding to the use of “system expansion via substitution” to avoid allocation when a unit process yields multiple co-products. This document applies to the CFP for hydrogen production.

This document provides requirements for the evaluation process of any flexible packaging with the main body of the packaging unit predominantly made of PE or PP and for the evaluation process of separate components predominantly made of flexible PE or flexible PP, with respect to compatibility of the design with state-of-the-art collecting, sorting and recycling processes, and the characterization of the output(s) compared to a reference material.
Packaging constituents and packaging components made of other materials than PE and PP are also covered by this document as they need to be evaluated on compatibility with PE or PP polymer recycling.

This document covers the design of any bottle with the main body of the packaging unit predominantly made of PET and the design of separate components predominantly made of PET, with respect to compatibility of the design with state-of-the-art collecting, sorting and recycling processes and useability of the recyclates in an application.
Packaging constituents and packaging components made of other materials than PET are also covered by this document as they need to be evaluated on compatibility with PET polymer recycling.

This document gives guidance on the procedure for the bioaccumulation of substances liable to cause atmospheric pollution. This is done by using the grass species Lolium multiflorum ssp. italicum designated hereafter as Italian rye-grass. It is an active biomonitoring approach insofar as the plants used are first cultivated in set conditions before being exposed at the monitoring locations in the field. The plants then record any pollution events that occur while they are being exposed, allowing such events to be accurately dated.
The document specifies a method for identification and localization of one or more single pollution sources and the tracking of their "plume" on a local or regional scale. The method described also offers a tool to monitor sites in the long term by the repeated application of a clearly defined procedure and to describe the local or regional air pollution situation.
The method described in this document is applicable to solid and gaseous substances deposited on plants, where they can accumulate on their surface or in their tissues. These substances include sulphur, chloride, fluoride and especially metals as well as low volatile organic and halo-organic compounds such as polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), polybrominated diphenyl ethers (PBDE), polychlorinated dibenzo dioxins (PCDD) and polychlorinated dibenzo furans (PCDF). It is as well possible to verify pesticides which are used in plant protection products. The range of potential substances can be expanded according to the task at hand and the capabilities of conducting trace analyses and assessment.
The method described in this document allows spatial and temporal comparisons and allows for screening, thus providing a first indication of risk. The results of grass culture studies can suggest risks to biota (e.g. via the food chain) which require further investigation.
The method described in this document does not replace physico-chemical methods of direct measurement or modelling of air pollutants and cannot be replaced by them for its part; it complements them by indicating biological effects.
Potential areas of deployment are:
-   permit procedures related to air pollution legislation;
-   preservation of evidence related to the code for protection from pollution;
-   monitoring of emission sources and performance control;
-   assessment of local-scale emission transport;
-   evidence of causation, e.g. related to environmental liability;
-   air quality maintenance plans/strategies;
-   long-term monitoring of ecological effects of atmospheric depositions;
-   detection and assessment of local, regional, and countrywide effects of atmospheric depositions;
-   assessment of risks for humans and/or animals via the food chain.
This document is of interest to those involved in environmental monitoring.

This document specifies the required characteristics of a light weight coaxial cable, 50 Ω, type KX for use in aircraft electrical systems at operating temperature between −55 °C and 200 °C and specially for high frequency up to 6 GHz. Nevertheless, if needed, −65 °C is also acceptable as shown by rapid change of temperature test.
