This document specifies the general “design for recycling” guidelines for EPS raw materials. It provides guidance on the impact of specific design characteristics on the recyclability of the product in practice and recommended design options to ensure that the product is recyclable, including target values and performance ranges, where applicable. It also provides a definition of recyclable product and of design for recycling.
This document refers to the recycling processes of EPS products. The sorting and collecting steps are not part of this document.
This document takes into account all currently known processes that are suitable to enable the circular economy for insulation materials. Particular attention is paid to ensuring that the most energy-efficient processes are given preference, especially mechanical recycling, unless reuse is already ruled out.
For some of these processes, practical experience has been gained over many years, so a basic knowledge base for the development of a guideline is already available.
At the same time, it is important to also take into account future-oriented processes, for which at the moment little but increasing experience is available or which have so far only been implemented on a small scale.

This document specifies general construction, performance and material requirements for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, elderly and disabled persons, the mixed water temperature needs to be set at a suitable bathing temperature (body temperature approximately 38 °C) as children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children during bathing.
It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilets and cloakrooms) and bath rooms operating under the conditions specified in Table 1.
This document allows TMVs to supply a single outlet or a small number of outlets in a "domestic" application (e.g. one valve controlling a shower, bath, basin and/or bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use).
The tests described are type tests (laboratory tests) and not quality control tests carried out during manufacture.

This document specifies the conditions for the determination of hoop tensile properties of ceramic 
matrix composite (CMC) tubes with continuous fibre-reinforcement at ambient temperature in air 
atmospheric pressure. This document is specific to the tubular geometries since fibre architecture and 
specimen geometry factors in composite tubes are distinctly different from those in flat specimens.
This document provides information on the hoop tensile properties and stress-strain response, such 
as hoop tensile strength, hoop tensile strain at failure and elastic constants. The information can be 
used for material development, control of manufacturing (quality insurance), material comparison, 
characterization, reliability and design data generation for tubular components.
This document addresses, but is not restricted to, various suggested test piece fabrication methods. 
It applies primarily to ceramic and/or glass matrix composite tubes with a continuous fibrous-
reinforcement: unidirectional (1D filament winding and tape lay-up), bi-directional (2D braid and 
weave) and tri-directional (xD, with 2 ; < x ; < 3), subjected to an internal pressure.
Values expressed in this document are in accordance with the International System of Units (SI).

TThis document specifies a test method and the minimum requirements for virucidal activity of chemical disinfectant and antiseptic products that form a homogeneous physically stable preparation when diluted with hard water - or in the case of ready-to-use products, i.e, products that are not diluted when applied, - with water. Ready-to-use-products can only be tested at a concentration up to 80 % (97 %, with a modified method for special cases) as some dilution is always produced by adding the test organisms and interfering substance.
This document applies to products that are used in the medical area in the fields of hygienic handrub, hygienic handwash, instrument disinfection by immersion, surface disinfection by wiping, spraying, flooding or other means and textile disinfection.
This document applies to areas and situations where disinfection is medically indicated. Such indications occur in patient care, for example:
- in hospitals, in community medical facilities, and in dental institutions;
- in clinics of schools, of kindergartens, and of nursing homes;
and can occur in the workplace and in the home. It can also include services such as laundries and kitchens supplying products directly for the patient.
NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.
NOTE 2 This method corresponds to a phase 2, step 1 test.
NOTE 3 EN 14885 specifies in detail the relationship of the various tests to one another and to "use recommendations".

This document specifies the general requirements for the preparation of samples and initial suspensions prior to microbiological examinations of soil improvers and growing media. This method is intended especially for sample preparation prior to microbiological examinations of e.g. E. coli, Salmonella spp. and Enterococcaceae.
Because of the large variety of soil improvers and growing media, this method might not be appropriate in every detail for certain materials. This method might not be appropriate in every detail for certain products. In this case, different methods which are specific to these products can be used if necessary, for justified technical reasons.

This document specifies the mathematical processing of digitized transverse profile measurements to produce indices in the transverse direction for unevenness, other defects and crossfall. The document describes the calculation methods of the indices such as irregularities (1) rut depth, (2) ridge height, (3) water depth and area, crossfall and how to evaluate and report the indices. It also describes possibilities to do further analysis to examine defects and problems on the road that can be seen in the transverse profile. The latter is described in Annex E, Other transverse indices (edge deformation/edge slump, crossfall line, rut area and width and the distance between the rut bottoms).
The quantified evenness indices derived from this document are useful support for quality control of newly laid pavement surfaces, especially with respect to the evidence of irregularities due to improper laying and/or compacting actions. It is also useful for evaluating the condition of pavements in service as part of routine condition monitoring programs, and finally as indices to be used for maintenance planning of resurfacing activities on pavements in use. The derived indices are portable in the sense that they can be obtained from transverse profiles measured with any suitable instrument.
All indices described in this document are related to the actual lane and direction of the road at which the measurement is done.
