Plastics piping systems for non-pressure underground drains and sewers - Unplasticized poly(vinyl chloride) (PVC-U) - Part 1: Specifications for pipes, fittings and the systems

This document specifies the definitions and requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drains and sewers for wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document also specifies test methods and test parameters. This document is applicable to: — solid wall pipes and fittings which are intended to be used buried underground outside the building structure reflected in the marking of the products by “U”, and — solid wall pipes and fittings which are intended to be used buried underground both outside (application area code “U”) and within the building structure reflecting on the marking of products by “UD”. NOTE 2 Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 13476-2 [1]. This document covers a range of pipe and fitting sizes, stiffness classes, and gives recommendations concerning colours. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with CEN/TS 1401-2 [7] it is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended for buried piping systems for non-pressure underground drains and sewers. NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 10 and to the requirements of Table 16.

Oil and gas industries including lower carbon energy - Cements and materials for well cementing - Part 1: Specification (ISO/DIS 10426-1:2026)

ISO 10426-1:2009 specifies requirements and gives recommendations for six classes of well cements, including their chemical and physical requirements and procedures for physical testing. ISO 10426-1:2009 is applicable to well cement classes A, B, C and D, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of class D cement. ISO 10426-1:2009 is also applicable to well cement classes G and H, which are the products obtained by grinding clinker with no additives other than one or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction.

Health informatics - Electronic health record communication - Part 4: Security (ISO/FDIS 13606-4:2026)

This document describes a methodology for specifying the privileges necessary to access EHR data. This methodology forms part of the overall EHR communications architecture defined in ISO 13606-1. This document seeks to address those requirements uniquely pertaining to EHR communications and to represent and communicate EHR-specific information that will inform an access decision. It also refers to general security requirements that apply to EHR communications and points at technical solutions and standards that specify details on services meeting these security needs. NOTE Security requirements for EHR systems not related to the communication of EHRs are outside the scope of this document.

Agricultural machinery - Safety - Part 6: Sprayers and liquid fertilizer distributors (ISO/DIS 4254-6:2026)

This document, to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed and self-propelled agricultural sprayers for use with plant protection products (PPP) and liquid fertilizer application, as placed on the market by the manufacturer and designed for a single operator only. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. When requirements of this document are different from those which are stated in ISO 4254-1, the requirements of this document take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the provisions of this document. This document, taken together with ISO 4254-1, deals with significant hazards, hazardous situations and events relevant to sprayers and liquid fertilizer distributors when they are used as intended and under the conditions foreseeable by the manufacturer (see Annex A), excepting the hazards arising from: — protection of the driver against spray when spraying (see Foreword); — automatically actuated height adjustment systems; — the environment, other than noise; — moving parts for power transmission except strength requirements for guards and barriers. This document is not applicable to sprayers and liquid fertilizer distributors which are manufactured before the date of publication of this document.
