Structural adhesives - Determination of the pot life and working life of multi-component adhesives (ISO/DIS 10364:2026)

This document specifies methods for determining the pot life of multi-part adhesives, in order to be able to determine whether the pot life conforms to the minimum specified working life required of an adhesive. The different methods described in this document to measure the property do not necessarily provide identical results. The test methods described are suitable for assessing all multi–part adhesives, and especially epoxy based and polyurethane based adhesives, but they are not suitable for some acrylic-based adhesives. NOTE 1 Some of the methods described in this document can also be suitable for determination of working life of one-part adhesives that react to humidity (e.g. PUR prepolymers). NOTE 2 This document can also be used for assessing non-structural adhesives.

Oil and gas industries including lower carbon energy - Qualification testing and acceptance criteria for protective coating systems under insulation - Part 1: Liquid applied coatings (ISO/DIS 19277-1:2026)

This document describes various corrosion under insulation (CUI) environments in refineries and other related industries and environments, and establishes CUI environmental categories including operating temperature ranges from −45 °C to 204 °C for topside and aboveground service only. This document specifies both established and other test methods for the assessment of coatings used for prevention of CUI for each given environment. This document also provides acceptance criteria for each CUI environment. NOTE The test results and acceptance criteria can be considered an aid in the selection of suitable coating systems. For service or peak temperatures below −45 °C an optional cryogenic test can be incorporated and for over 204 °C testing acceptance criteria can be agreed between interested parties. Additional or other test and acceptance measures are possible, but require particular agreement between the interested parties. This document covers spray-applied coatings applied on new carbon and austenitic stainless steel for use in CUI service. This document does not cover testing of sacrificial coatings, such as inorganic zinc, as these coatings can be consumed quickly in wet environments. Developing accelerated corrosion testing for what can be continuous wet service with sacrificial coatings is beyond the scope of this document. "Non-through porosity" thermal spray aluminium coatings with greater than 250 µm dry film thickness can be tested and qualified in accordance with this document. This document does not cover tape and sheet applied products for use in preventing CUI. This document does not deal with other aspects of coating degradation, such as those caused by abrasion, erosion, ultraviolet degradation or other methods that can exist given specific environment and construction methods.

Small craft - Stability and buoyancy assessment and categorization - Part 2: Sailing boats (ISO/DIS 12217-2:2026)

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 load. This document is principally applicable to boats propelled primarily by sail (even if fitted with an auxiliary engine) of 6 m up to and including 24 m hull length. However, it can also be applied to boats less than 6 m if they are habitable multihulls or can be applied 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; — gondolas and pedalos; — surfboards including sailing surfboards; and — hydrofoils and foil stabilized boats when not operating in the displacement mode. 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 - Determination of the dry matter content

This document specifies the procedure for the determination and calculation of the dry matter content of organic and organo-mineral fertilizers for which the results of the performed analysis are to be calculated to the dry matter content basis. This document is applicable and validated for several types of matrices as indicated in Annex A. This document is applicable to the component materials “by-products”, “thermal oxidation materials and derivatives”, or “recovered high-purity materials”, 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 fertilizers 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.

Railway applications - Simulation Credibility

This document sets out a framework to replace and/or complement physical tests with virtual tests by introducing simulation credibility for a given railway application. This covers simulation development, use, and management. Users of this document can be: - simulation engineers or organizations and their subcontractors, - standardization working groups to introduce simulations in their standards or - technical assessors and conformity assessment bodies. This document provides guidance, particularly when simulations are not yet defined. Where applicable, this document can be used in conjunction with existing standards pertaining to the use of simulations. If simulation is already recognized in existing domain-specific standards, this document does not modify the requirements of those standards. However, it may assist in future improvements and harmonization. It does not provide domain-specific guidance on applying simulations. For the use of technologies including, but not limited to, artificial intelligence, model-scale testing, and distributed computing, relevant potential technology based risks can arise.
