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.

Eurocode 8 - Design of structures for earthquake resistance - Part 2: Bridges

EN 1998-2 is intended to be applied to the design of new bridges in seismic regions. It covers the design of reinforced concrete, steel and composite steel-concrete bridges and provides guidance for the design of timber bridges. EN 1998-2 is applicable to the seismic design of bridges exploiting ductility in structural members or through the use of antiseismic devices. When ductility is exploited, this part primarily covers bridges in which the horizontal seismic actions are mainly resisted through bending of the piers or at the abutments; i.e. of bridges composed of vertical or nearly vertical pier systems supporting the traffic deck superstructure. It is also applicable to the seismic design of arched bridges, although its provisions should not be considered as fully covering these cases. Suspension bridges and masonry bridges, moveable bridges and floating bridges are not included in the scope of EN 1998-2.

Inorganic fertilizers - Determination of the chloride content in ammonium nitrate fertilizers of high nitrogen content

This document specifies a method for the determination of the chloride content in ammonium nitrate fertilizers of high nitrogen content. This document is applicable to 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: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic 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.

Foodstuffs - Detection of food allergens by molecular biological methods - Part 7: Peanut (Arachis hypogaea) - Qualitative detection of a specific DNA sequence in food by real-time PCR

This document specifies a method for the qualitative detection of peanut (Arachis hypogaea) DNA in food using real-time PCR and targeting a multicopy mitochondrial sequence, in the context of allergen analyses. The method was previously validated in an interlaboratory study (ring trial) and applied to DNA extracted from samples that consist of defined proportions of peanut in rice biscuits, wheat biscuits, cooked sausage and milk powder. The limit of detection of the peanut real-time PCR has been determined experimentally to be at least 0,5 mg peanut/kg.

Road and airfield surface characteristics - Test methods - Part 4: Method for measurement of slip/skid resistance of a surface: The pendulum test

This document describes a method for determining the slip/skid resistance of a surface using a device which remains stationary at the test location. The slip/skid resistance is measured by means of a slider mounted at the end of a pendulum arm. The method provides a measure of the slip/skid resistance properties of a wetted surface either in the field or in the laboratory. This method measures the slip/skid resistance of a small area of a surface (approximately 0,01 m2). It is important to consider this when deciding its applicability to a surface which might have nonhomogeneous surface characteristics, e.g. containing ridges or grooves, or is rough textured (exceeding 1,5 mm mean texture depth).

The document describes the transactions for pre-award processes between Contracting Entities (Buyer) and Economic Operators (Seller), where the Buyer seeks to establish a contract for the procurement of products, services, or works. The various possible behaviours of Buyers and Sellers are represented through choreography variants as described in prEN 17014-2:2025 [7]. This document specifies the transactions described by the choreography variants and captures their specific functional and informational aspects. The transactions are grouped along the following collaborations which are applied in pre-award choreographies: — Procurement procedure subscription — Procurement documents access — Tender submission — Procurement documents questions and answers — Tender clarification — Tender withdrawal — Notify awarding — Tendering message response — Tenderer qualification — Qualification response — Invitation to tender For each transaction, the document specifies the underlying business and information requirements, including the functional and procedural objectives the transaction must fulfil, the structure and semantics of the related data, and the governing business rules ensuring valid execution. In addition, all defined data elements are aligned with the eProcurement Ontology (ePO) to achieve semantic interoperability and consistent representation across procurement systems. This document is linked to Directive 2014/24/EC on public procurement [8], Directive 2014/25/EC on procurement by entities operating in the water, energy, transport and postal services sectors [9], Directive 2014/23/EC on the award of concession contracts [10] and Directive 2009 /81/EC on the coordination of procedures for the award of contracts in the fields of defence and security [11].
