Methods of testing cement - Part 15 - Sulfate resistance - Flat prism method

This document describes test methods (reference and alternative) applicable to cast test specimens for evaluating the Sulftate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks. In these methods, the test is carried out under controlled exposure conditions using an increased concentration of sulfate solution. These test conditions are intended to accelerate external sulfate attack. The reference test method is adapted from the modified SVA test method (German Institute for Building Technology (DIBt), Expert Committee (SVA)): “Testing the Sulfate Resistance of Cements with pozzolanic main constituents”. The modified SVA test method is listed in European Assessment Document – EAD 150007-01-0301, Annex C. This test method is appropriate for various binders, in particular those with pozzolanic main constituents. The alternative test method is listed in European Assessment Document – EAD 150009-01-0301, Annex A. This test method is appropriate for CEM III/A cements.

Secondary batteries for light means of transport - Part 1: Test specifications for performance and durability aspects for lithium-ion and sodium-ion batteries

This European standard specifies test procedures for performance and durability aspects of light means of transport (LMT) batteries. These are sealed batteries with a maximum weight of 25 kg that are specifically designed to provide electric power for the traction of wheeled vehicles that can be propelled by an electric motor alone or by a combination of motor and human power, including type-approved vehicles of category L within the meaning of Regulation (EU) No 168/2013 of the European Parliament and of the Council, and that is not an electric vehicle battery. The scope of this document is restricted to lithium-ion batteries. LMT batteries contain at least the following general classes: • Batteries of L-category vehicles referred to in Article 2 of Regulation EU 168/2013 of the European Parliament and of the Council (e.g., batteries for light motorcycles, trikes and quads), where the battery weight is less than 25 kg. • Batteries for EPACs (electronically power assisted cycle) with or without type approval • Batteries for micro mobility devices like e.g., e-kick-scooters, hoverboards, self-balancing vehicles… Batteries above 25 kg for mobility are not in the scope of this standard, even though they may be used in L category vehicles (e.g. L7 category). Batteries for toys are also not in the scope of this standard based on the recital 15 of (EU) 2023/1542: "Batteries used for traction in wheeled vehicles considered to be toys within the meaning of Directive 2009/48/EC of the European Parliament and of the Council, should, for the purposes of this Regulation, not be considered to be LMT batteries, but to be portable batteries." For reused, remanufactured, repaired and repurposed (here further called “R”) batteries the same procedures have to be applied. The tests listed here have to be conducted and documented. If this is not possible, equivalent tests have to be performed. However, this document does not aim to specify detailed test procedures specifically for these kinds of “R”-batteries.

Non-destructive testing of welds - Ultrasonic testing - Acceptance levels (ISO/DIS 11666:2026)

ISO 11666:2018 specifies two ultrasonic acceptance levels known as acceptance level 2 (AL 2) and acceptance level 3 (AL 3) for full penetration welded joints in ferritic steels, which correspond to ISO 5817:2014, quality levels B and C. An acceptance level corresponding to ISO 5817:2014, quality level D is not included in this document, as ultrasonic testing is generally not requested for this weld quality. These acceptance levels are applicable to testing carried out in accordance with ISO 17640. ISO 11666:2018 applies to the testing of full penetration ferritic steel welds, with thicknesses from 8 mm to 100 mm. It can also be used for other types of welds, materials and thicknesses, provided the tests have been performed with necessary consideration of the geometry and acoustic properties of the component, and an adequate sensitivity can be employed to enable the acceptance levels of this document to be applied. The nominal frequency of probes used in this document is between 2 MHz and 5 MHz, unless attenuation or requirements for higher resolution call for other frequencies. It is important to consider the use of these acceptance levels in conjunction with frequencies outside this range carefully.

Eurocode 5 - Design of timber structures - Part 3: Execution

1.1 Scope of EN 1995-3 (1) This document gives minimum requirements for execution of timber structures (buildings and bridges) designed in accordance with EN 1995 (all parts) to ensure that what is built meets the requirements for mechanical resistance, serviceability, durability, and fire performance. (2) This document gives guidance on moisture control during transport to the building site, storage on site, handling on site and erection. (3) This document gives guidance on workmanship and deviation limits during execution. (4) This document assumes that there is an execution specification which states all the specific requirements relevant for the execution of a particular structure. (5) For products covered by a European technical product specification, this document only covers those aspects of fabrication such as cutting, machining and drilling after placement of the product on the market. (6) This document does not cover: a) parts which are not designed according to EN 1995; b) temporary works (such as formwork, scaffolding, propping, shoring, etc.); c) specification, production and conformity of timber members in accordance with European technical product specifications; d) deviation limits for other properties than mechanical resistance, serviceability, durability and fire performance; e) contractual aspects, responsibilities of the various parties, competency requirements or the degree of independence of the personnel undertaking the inspection; f) health and safety requirements during execution. 1.2 Assumptions (1) It is assumed that all relevant provisions of EN 1995 are complied with. (2) It is recognized in this document that areas such as detailed requirements for competence of personnel, and details related to Quality Management are within the competence of the CEN Member States. (3) Before the execution begins on a part of the structure, it is assumed that the following are available on site: — the drawings and specification of that part; — the execution specification. (4) Before the start of the execution, it is assumed that the execution specification has been checked for completeness. (5) It is assumed that previous work (such as foundations) has been inspected and that any work which needs to be done due to deviations from the execution specification has been carried out.

This document specifies a method for the determination of extractable metals in leather using extraction with an acid artificial-perspiration solution and subsequent determination with inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA). This method determines extractable metals in leather; it is not compound-specific or specific to the oxidation state of the metals. This method is especially suitable for determining the extractable chromium in chromium-tanned leathers.
