Plastics piping systems for non-pressure underground drainage and sewerage - Unplasticized poly(vinyl chloride) (PVC-U) - Part 2: Guidance for the assessment of conformity
This document gives requirements and guidance for the assessment of conformity of formulations, products and assemblies in accordance with EN 1401 1 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of third-party certification procedures. NOTE 1 The quality management system is expected to conform to or is no less stringent than the relevant requirements to EN ISO 9001 [1]. NOTE 2 If third party certification is involved, the certification body is expected be compliant with either EN ISO/IEC 17065 [2] or EN ISO/IEC 17021-series [3], as applicable. NOTE 3 In order to help the reader, a basic test matrix is given in Annex A. In conjunction with EN 1401 1, this document is applicable to piping systems made of unplasticized poly(vinyl chloride) (PVC-U) intended for non-pressure underground drainage and sewerage: - buried in ground outside the building structure (application area code “U”); - both buried in ground within the building structure and outside the building structure (application area code "UD"

Patient involvement in health care - Minimum requirements for person-centred care
This document specifies minimum requirements for patient involvement in health care services with the aim to create favourable structural conditions for person-centred care. It is applicable for use before, during and after the actual care that is provided by the care personnel. This document is also applicable for use on a strategic level for quality assurance and quality improvement, for procurement, educational and supervisory purposes and as a guiding document for research and development projects in the field of intervention and implementation of person-centred care.

Railway applications - Fixed installations - Electrical protective measures for working on or near an overhead contact line system and/or its associated return circuit
This document provides requirements for electrical safety for: - dead working on an overhead contact line system; - working activities near an overhead contact line system when it is live. It applies to all work activities in relation to electrical hazards only. This document is applicable to overhead contact line systems with the following nominal voltages: - 1,5 kV and 3 kV dc; - 15 kV, 2x15 kV, 25 kV and 2x25 kV ac. It also provides requirements for work activities that can give rise to electrical hazards from the return circuit. This document does not cover electrical risk arising from: - live working on overhead contact line systems (live working can be carried out according to national requirements and practices); - working on or near other electrical sources. If there are no other rules or procedures, this document could be applied to overhead contact line systems with other nominal voltages.

Solid recovered fuels - Methods for the determination of biomass content (ISO 21644:2021)
This International Standard specifies two methods for the determination of the biomass content in solid recovered fuels: the selective dissolution and the 14C content method. The standard provides the criteria for choosing the more appropriate method and some examples of application.
