In this context “gas” refers to flammable gas: — which is in a gaseous state at a temperature of 15 °C and under a pressure of 0,1 MPa (the stored product is also named fluid); — which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfils contractual requirements. This comprises: — gas not in liquid phase under subsurface conditions; — methane-rich gases; — natural gas; — biomethane; — synthetic methane; — hydrogen of various purities; — any mixtures of the gases above; — hydrocarbon gas in liquid phase under subsurface conditions such as; — ethylene; — liquified petroleum gas (LPG). NOTE 1 Correspondingly the EN 1918 series can be considered where applicable for underground storage of any other fluid e.g. helium, carbon dioxide, compressed air, rDME (renewable dimethyl ether) and hydrogen transport fluids (such as ammonia and LOHC). This document is not intended to be applied retrospectively to existing facilities. NOTE 2 Correspondingly this document can be considered for major conversions in case of significant change of gas composition.

Neardomieji bandymai. Radiografinis tyrimas. Pramoninių radiografinių šaltinių matmenų nustatymas (ISO 32679:2024)

This document specifies a test procedure for determination of the size of industrial radiographic gamma sources of 0,5 mm or greater, made from the radionuclides Iridium 192, Ytterbium 169, Selenium 75 or Cobalt 60, by a radiography method with X-rays. The source size of a gamma radiation source is an important factor which affects the image quality of gamma ray images. The source size is determined with an accuracy of ±10 % but typically not better than ±0,1 mm. The source size is provided by the manufacturer as the mechanical dimension of the source insert. A measurement can be required if the manufacturing process is validated or monitored after implementation of the source into the holder. This document can be used for other radionuclides after validation. The standard test method ASTM E1114 provides further information on the measurement of the Ir-192 source size, the characterization of the source shape, and its correct assembly and packaging.

Specialiųjų geotechnikos darbų atlikimas. Grunto maišymas vietoje

This document specifies general principles for the execution, supervision, inspection, testing and monitoring of in situ soil mixing works (Deep Mixing) carried out by two different methods: dry mixing and wet mixing. Soil mixing considered in this document is limited to methods which involve: - mixing by rotating mechanical mixing tools, including jetting and/or compressed air assistance, where the lateral support provided by the surrounding ground is not removed; - different shapes and configurations of soil mixing elements, either columns, panels, walls or any combination of more than one single element, with or without overlapping; - treatment of soils and fills, including brownfields, sludges, etc., with possible limited penetration into the rock; - mass mixing; - environmental mixing, involving installation of containment and permeable reactive barriers and solidification/stabilization of contaminated soils and sludges. This standard does not apply to shallow soil stabilization, which consists of granulating the surface soil and mixing it with binder using soil stabilizing machines to improve soil performance as an alternative to soil replacement, typically in road works.

This document specifies requirements on the development and implementation of a Safety Management System (SMS) and a Pipeline Integrity Management System (PIMS). The SMS is applicable for system operators of a gas infrastructure. The PIMS is applicable for system operators of gas infrastructure with a maximum operating pressure (MOP) over 16 bar. This document refers to all activities and processes related to safety aspects and performed by system operators of a gas infrastructure, including those activities entrusted to contractors. It includes safety-related provisions on operation of the gas infrastructure. This document is applicable to infrastructure for the conveyance of processed, non-toxic and non-corrosive natural gas according to EN ISO 13686 and gases such as biomethane and hydrogen and to mixtures of these gases with natural gas. This document covers also gases classified as group H, that are to be transmitted, injected into and from storages, distributed and utilized, as specified in EN 16726. For the requirements and test methods for biomethane at the point of entry into a natural gas network, reference is made to EN 16723-1. This document can be applied for gas infrastructure conveying gases of the 3rd gas family as classified in EN 437 or for other gases such as carbon dioxide. Specific requirements for occupational health and safety are excluded from this document. For these, other European and/or international standards, e.g. ISO 45001, apply. This document specifies common basic principles for gas infrastructure. It is important that users of this document are expected to be aware that more detailed national standards and/or codes of practice exist in the CEN member countries. This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles. In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this document, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). NOTE CEN/TR 13737 (all parts) contains: - clarification of relevant legislation/regulations applicable in a country; - if appropriate, more restrictive national requirements; - national contact points for the latest information.

This European standard specifies a laboratory method for the determination of the carotenoid content in microalgae. The method is based on the development of the chlorophyll a standard, which resulted in prEN 18034. This method has been validated for the microalgae species Nannochloropsis and Phaodactlylum. This standard is only validated for fucoxanthin, beta carotene and lutein content, but could be used for other carotenoids as well. Given small adaptations to be able to measure smaller concentrations, this method could also be used for macro algae. This standard is developed in CEN/TC 454/WG 6 Product test methods.
