Oil and gas industries including lower carbon energy - Materials for use in H2S-containing environments in oil and gas production - Part 2: Service environment assessment and material selection (ISO/DIS 15156-2:2025)

This document gives requirements and recommendations for the selection and qualification of carbon and low-alloy steels for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements of the appropriate design codes, standards or regulations. This document addresses the resistance of these steels to damage that can be caused by sulfide stress cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC). This document also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and its possible development into stepwise cracking (SWC). This document is concerned only with cracking. Loss of material by general (mass loss) or localized corrosion is not addressed. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions. This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see ISO 15156-1:2020, Clause 5. Annex A lists SSC-resistant carbon and low alloy steels, and A.2.4 includes requirements for the use of cast irons. This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.

Plastics pipes for the conveyance of fluids under pressure - Miner's rule - Calculation method for cumulative damage (ISO/DIS 13760:2026)

In general terms, Miner’s rule is a common approach to calculate how the accumulation of a specific load that varies over time effects the time until failure. This international standard specifies the application of Miner’s rule for calculating the design time until failure of plastics pipes and piping systems of plastics materials under varying, but known, load conditions. Miner’s rule can also be applied reciprocally to calculate the tolerable load levels along a desired design time. This international standard specifies particularly the application of Miner’s rule to calculate stress or pressure regimes, respectively, that are tolerable during a targeted design time for plastics or composite pipes. Further, the application of Miner’s rule on the effect of accumulated damage on polyolefins caused by oxidative attack under varying temperatures and times on the design life is specified. It is necessary to apply Miner's rule to each failure mechanism separately. Thus, for mechanical failure due to internal pressure, other failure mechanisms, such as oxidative or dehydrochlorinative degradative failure mechanisms, are to be neglected (assuming, of course, no interaction). A material may be used only when it is proven to conform to all failure mechanism criteria. NOTE Miner's rule is an empirically based procedure and is only a first approximation to reality.

Railway applications - Testing and simulation for the acceptance of running characteristics of railway vehicles - Running safety under longitudinal compressive force

This document defines the assessment of endurable longitudinal compressive force (LCF) of a vehicle. The endurable longitudinal compressive force is a parameter depending on the vehicle design. It is used to estimate the risk of derailment of a vehicle as a result of being subjected to longitudinal compressive force, under operating conditions. NOTE 1 As operating conditions can vary in several aspects (infrastructure, train configurations etc.), this document defines uniform assessments of endurable longitudinal compressive force per vehicle in specific operating conditions. The main assessment of endurable longitudinal compressive force for conventional trains is derived from UIC 530-2:2011, which is based on practical tests performed in ERRI-B12. Assessments of endurable longitudinal compressive force for high-capacity trains in this document are required by the methodology of IRS 40421. IRS 40421 assesses operational train parameters. This document applies to the following types of vehicles: - single wagons; - permanently coupled units with standard ends between the vehicles; - permanently coupled units with diagonal buffers and screw couplers between the vehicles; - permanently coupled units with a bar coupler between the vehicles; - articulated units with 2-axle bogies; - wagons with 3-axle bogies; - low-floor wagons with eight or more axles (e.g. rolling road wagon); - vehicles with centre couplers; - railbound construction and maintenance machines as defined in EN 14033-1:2017. NOTE 2 This document defines the acceptance process to be followed by vehicles that are operated in a way that high longitudinal compressive force occur in the trains due to their operational environment (e.g. train composition, brake mode, track layout). The following vehicles are not in the scope of this document: - locomotives and passenger rolling stocks; - vehicles that are only operated in passenger trains. NOTE 3 Locomotives, passenger rolling stocks and vehicles operated in passenger trains only are not in the scope of this document as they either are subject to low longitudinal compressive force in operation or have sufficient endurable longitudinal compressive force due to their axle load. Acceptance criteria and test conditions as well as conditions for simulation are defined in this document. Conditions for dispensation of the assessment of the endurable longitudinal compressive force are also defined in this document. This document applies principally to vehicles which operate without restrictions on tracks with a gauge of 1 435 mm in Europe. NOTE 4 The influence on railway systems using other gauges is not sufficiently understood to extend the scope of this document to gauges other than 1 435 mm. NOTE 5 For wagons with centre couplers, a need for assessment of derailment risk due to Longitudinal Forces on other gauges (1 524 mm, 1 600 mm, 1 668 mm) has been expressed. The influence on railway systems using other gauges is not sufficiently understood. This document only introduces some notions to assess it independently from the gauge.

Small craft - Stability and buoyancy assessment and categorization - Part 1: Non-sailing boats (ISO/DIS 12217-1:2026)

This document specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats susceptible to swamping are also encompassed. The evaluation of stability and buoyancy properties using this document will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum total load. This document is principally applicable to boats propelled by human or mechanical power of 6 m up to 24 m hull length. However, it can also be applied to boats of under 6 m if they do not attain the desired design category specified in ISO 12217‑3 and they are decked and have quick-draining recesses which comply with ISO 11812. In relation to habitable multihulls, this document includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation. This document excludes: —    inflatable and rigid-inflatable boats covered by the ISO 6185 series, except for references made in the ISO 6185 series to specific clauses of the ISO 12217 series; —    personal watercraft covered by ISO 13590 and other similar powered craft; —    gondolas and pedalos; —    sailing surfboards; —    surfboards, including powered surfboards; —    hydrofoils and hovercraft when not operating in the displacement mode; and —    submersibles. NOTE       Displacement mode means that the boat is only supported by hydrostatic forces. It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.

Organic and organo-mineral fertilizers - Digestion by aqua regia for subsequent determination of elements

This document specifies the procedure for digestion of different organic and organo-mineral fertilizers with aqua regia to enable a subsequent determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni), boron (B), cobalt (Co), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), mercury (Hg), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sulfur (S) and sodium (Na)). This document is applicable to the component materials “by-products”, when used as components of fertilizing products, as well as the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible. The digests are suitable for analysis using prEN 17770 [11] and prEN 17769 [10]. This document is applicable and validated for several types of matrices as indicated in Annex A. NOTE 1 Digestates prepared by the procedure given in this document can also be applied for determination of other elements. NOTE 2 Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results.
