Cryogenic vessels - Gas/material compatibility (ISO/DIS 21010:2025)

ISO 21010:2017 specifies gas/material compatibility requirements (such as chemical resistance) for cryogenic vessels, but it does not cover mechanical properties (e.g. for low-temperature applications). ISO 21010:2017 provides general guidance for compatibility with gases and detailed compatibility requirements for oxygen and oxygen-enriched atmospheres. This document also defines the testing methods for establishing oxygen compatibility of materials (metallic and non-metallic) to be used for cryogenic vessels and associated equipment. ISO 21010:2017 focuses on materials that are normally with or could be in contact with cryogenic fluids.

Piping systems for rehabilitation of underground drains, sewers and water supply networks - Part 4: Thermoplastic composite materials (ISO/DIS 11300‑4:2025)

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the renovation of underground non-pressure drainage and sewerage networks. It is applicable to pipes, fittings and assemblies, made from thermoplastic composite materials, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with spirally-wound (SWO) pipes; — lining with a rigidly anchored plastic inner layer (RAPL). and intended to be used at an operating temperature of 20 °C as the reference temperature. In the case of lining with SWO pipes, where the pipes, are formed on site, to a fixed or variable diameter, by spirally winding and jointing a pre-manufactured profiled plastics strip, this document applies to, strips made of unplasticized poly(vinyl chloride) (PVC U), or of polyethylene (PE), with or without steel stiffening elements, and installed with or without integral locking mechanism. In the case of lining with RAPL, where a single rigid annulus of structural cementitious grout is formed behind a plastics inner layer serving as permanent formwork anchored to the grout. This document applies to integrally joined profiled plastics strips of PVC-U or PE or studded sheets of PE, and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system. NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.

Clinical evaluation of medical devices (ISO/DIS 18969:2025)

This document specifies terminology, principles and a process for the clinical evaluation of medical devices. The process described in this document aims to assist manufacturers of medical devices to estimate the clinical risks associated with a medical device and evaluate the acceptability of those risks in the light of the clinical benefits achieved when the device is used as intended. The requirements of this document are applicable throughout the life cycle of a medical device. The process described in this document applies to the assessment of risks and benefits from clinical data obtained from the use of medical devices in humans. This document specifies general requirements intended to — verify the safety of medical devices when used in accordance with their instructions for use; — verify that the clinical performance or effectiveness of a medical device meet the claims of the manufacturer in relation to its intended use; — verify that there is sufficient clinical evidence to demonstrate the achievement of a positive benefit/risk balance when a medical device is used in the intended patient population in accordance with its intended use; — ensure the scientific conduct of a clinical evaluation and the credibility of conclusions drawn on the safety and performance of a medical device; — define the responsibilities of the manufacturer and those conducting or contributing to a clinical evaluation; and — assist manufacturers, clinicians, regulatory authorities and other bodies involved in the conformity assessment of medical devices. Note 1 This standard can be used for regulatory purposes. Note 2 This document does not apply to in vitro diagnostic medical devices. However, there may be situations, dependent on the device and national or regional requirements, where sections and/or requirements of this document might be applicable.

This document specifies the requirements for an environmental management system that an organization can use to enhance its environmental performance. It is intended for use by an organization seeking to manage its environmental responsibilities in a systematic manner that contributes to the environmental pillar of sustainability. This document helps an organization to achieve the intended outcomes of its environmental management system, which provide value for the environment, the organization itself and interested parties. The intended outcomes of an environmental management system include: — enhancing environmental performance; — meeting compliance obligations; — achieving environmental objectives. This document is applicable to any organization, regardless of size, type and nature, and applies to the environmental aspects of its activities, products and services that the organization determines it can either control or influence considering a life cycle perspective. This document does not state specific environmental performance criteria. This document can be used in whole or in part to systematically improve environmental management. Claims of conformity to this document, however, are not acceptable unless all its requirements are incorporated into an organization’s environmental management system and fulfilled without exclusion.

Oil and gas industries including lower carbon energy - Pipeline transportation systems - Design, construction and maintenance of steel cased pipelines (ISO/DIS 16440:2025)

ISO 16440:2016 specifies requirements, including corrosion protection, for the design, fabrication, installation and maintenance of steel-cased pipelines for pipeline transportation systems in the petroleum and natural gas industries in accordance with ISO 13623. NOTE 1 Steel casings can be used for mechanical protection of pipelines at crossings, such as at roads and railways and the installation of a casing at a highway, railway, or other crossing can be required by the permitting agency or pipeline operator. NOTE 2 This document does not imply that utilization of casings is mandatory or necessary. NOTE 3 This document does not imply that cased crossings, whether electrically isolated or electrically shorted, contribute to corrosion of a carrier pipe within a cased crossing. However, cased crossings can adversely affect the integrity of the carrier pipe by shielding cathodic protection (CP) current to the carrier pipe or reducing the CP effectiveness on the carrier pipe in the vicinity of the casing. Their use is not recommended unless required by load considerations, unstable soil conditions, or when their use is dictated by sound engineering practices.
