This document describes procedures for the testing of dyed paper and board intended to come into contact with foodstuffs. Some procedures depending on the foreseeable use of the material are given.
Visual evaluation against a grey scale provides grading of the bleeding.
For samples having significant different sides, a migration can occur from one glass fibre to the other and could lead to wrong interpretation of the fastness of one side. It is advisable to check these samples using large sampling procedure to prevent cross contamination of the glass fibre during the migration procedure. The procedure is described in Annex A. If lower limit of detection is required, this procedure could also be used.

The work item aims to differentiate between biodegradable and non-biodegradable plastic materials. Non-biodegradable plastics are defined as those plastics which do not biodegrade, even in conditions which are conducive to the process. In contrast, the biodegradation of biodegradable plastics occurs when they come into contact with active microorganisms, under conditions that are conducive to biodegradation. This process is analogous to the biodegradation of natural polymers. The plastic materials that are categorised as being intrinsically biodegradable can be utilised in the design of products with a high risk of dispersion. The test scheme is not intended to be applicable to any specific application. Instead, the objective is to develop a framework methodology that can be utilised across diverse industrial sectors for the identification of biodegradable plastics, with the subsequent application of these plastics in the manufacture of various products and for different purposes. The work item does not intend to characterise and evaluate the environmental impact of products containing plastics identified as biodegradable. The test scheme should address the definition of intrinsic biodegradability of plastic materials, without determining the hazard potential of the products, which necessitates a distinct assessment that extends beyond the scope of this particular work item. The rate of biodegradation of a plastic object is not the focus of this particular work item, as it is contingent on environmental conditions. The test scheme to be developed will not be sufficient to carry out an analysis of the ecological risk associated with the dispersal of products, as this requires an assessment of the intrinsic hazard, of the environmental fate, in addition to the assessment of biodegradability.

This document specifies the safety requirements and test methods for soft carriers without a framed support designed to carry one or two children hands free when attached to the carer’s torso. 
If the soft carrier has functions not covered in this document, reference can be made to the relevant European Standard.
This document does not apply to garment or apparel carriers or carriers in the scope of prEN 13209-3:2026.
This document does not cover baby carriers designed for children with special needs.

This document specifies characteristics concerning the design and performance requirements together with type testing and on-site testing procedures especially for ducted filtration fume cupboards (DFFCs) not described in the other parts of EN 14175. Filters in DFFCs can be specific filters or a combination of filters dependent on the characteristics of the contaminants to be removed. 
This part of EN 14175 is related to and refers to other parts of EN 14175 regarding definitions, technologies, testing methodologies, design factors and functional aspects and is read in conjunction with these.
This standard covers the specific layout version of ducted fume cupboards with integral filtration. These devices called ducted filtration fume cupboards  can be designed to partially reuse filtered air for internal dilution. Therefore, the term “hybrid” fume cupboards is sometimes used.
Fume cupboards with associated filters are considered as standard fume cupboards according EN 14175 1 to EN 14175 3. 
NOTE Their filter requirements, description and testing are listed in Annex A for information.
The requirements for fume cupboards and filters for radioactive work are described in detail in EN 14175 8.
Recirculatory filtration fume cabinets which return the filtered exhaust air back into the surrounding room are not part of this document but described in prEN 17242.
DFFCs are not foreseen for work with pathogens. Appropriate microbiological cabinets are described in the EN 12469 series.

This document is applicable to endodontic ultrasonic inserts, operated in combination with either air or electrically powered stand-alone handpieces or handpieces connecting to dental units. This document specifies requirements and test methods for inserts, and requirements for marking, labeling and packaging.

This document defines terms for microlens arrays. It applies to arrays of very small lenses formed inside or on one or more surfaces of a common substrate. This document also applies to systems of microlens arrays.

This European Standard specifies the conventions and mathematical procedures to be adopted in calculating the photometric performance of road lighting installations designed in accordance with the parameters described in EN 13201-2 to ensure that every lighting calculation is based on the same mathematical principles.
The design procedure of a lighting installation also requires the knowledge of the parameters involved in the described model, their tolerances and variability. These aspects are not considered in this part of EN 13201 but a procedure to analyse their contribution in the expected results is suggested in EN 13201-4 and it can also be used in the design phase.

This document defines cyber security requirements for products with digital elements belonging to product category “Hardware Device with Security Boxes” (hereinafter called “Product” or “HWSB product”).
The technical description of “Hardware Devices with Security Boxes” can be found in Annex II of [CRA].
The Hardware Devices with Security Boxes in scope are designed for deployment in a range of environments and where the threat landscape includes attackers with various attack potential.
HWSB are hardware-based systems intended to provide secure storage, processing and use of sensitive data, including cryptographic assets, within a protected hardware boundary (envelope).
This document applies to the HWSB part of the product. The applicability of this document to specific products is determined based on their intended purpose, use case and risk assessment.

This document specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile test in order to determine the short-term tensile welding factor.
A tensile test can be used in conjunction with other tests (e.g. bend, tensile creep, macro) to assess the performance of welded assemblies, made from thermoplastics materials.
The test is applicable to welded semi-finished products made from thermoplastics materials filled or unfilled, but not reinforced, irrespective of the welding process used.

This document specifies guidelines and recommendations to be followed prior to carrying out
dimensional measurements on three-dimensional (3D) volumetric X-ray Computed Tomographic (XCT)
images of additive manufacturing (AM) series production parts. It is applicable to cone beam XCT
systems. However, these guidelines and recommendations can easily be transposed to fan beam XCT
systems.
The process to be followed prior to performing dimensional measurement on 3D volumetric XCT
images of AM series production parts, in this standard, is divided into two steps:
Step 1: Quantification of an XCT system performance, in terms of image quality and basic
dimensional measurement accuracy, with a reference object and eventually a Representative Quality
Indicators (RQI), with the specific part (part chosen from the AM series production parts) XCT setting
under certain environmental conditions. This step leads to the determination of the image quality, the
voxel size and the basic dimensional measurement accuracy of an XCT system;
Step 2: Validation of the XCT system compliance, in terms of dimensional measurement accuracy,
with the specific part, with the chosen XCT setting under the specific environmental conditions. This
step leads to a simplified determination of the dimensional measurement uncertainty of each
measurand of the specific part.
If step 1 does not comply with the set requirements, the XCT system cannot be used for step 2.
This document does not claim to provide a definitive method to determine XCT dimensional
measurement accuracy, which, given the complexity of an XCT process, is not yet established. For the
same reason, it is addressed to qualified XCT operators with the support of metrology experts.
This document is dedicated to AM series production parts and its aim is to provide a methodology for
controlling the geometric specificities associated with AM (internal shapes, lattice structures). It is
applicable on parts that are fabricated by any type of AM categories of processes and material
provided the X-ray penetration lengths are sufficient to scan the test part.
These prior quantification and validation processes, which allow dimensional measurements to be carry
out on 3D volumetric XCT images of AM series production parts, are valid for a specific part geometry
in a given material associated with a chosen XCT setting (magnification ; & XCT acquisition and
reconstruction parameters of the specific part) under specific environmental conditions for the
measurands specified. The quantification and validation processes are reconsidered when different
geometry of the part or material or XCT setting or environmental conditions or measurands are taken
into account.
