In this document, the pozzolanicity of a cement is assessed by comparing the concentration of calcium ion, expressed as calcium oxide, present in the aqueous solution in contact with the hydrated cement, after a fixed period of time, with the quantity of calcium ion capable of saturating a solution of the same alkalinity.

 

This European Standard specifies a method for the determination of mercury in digests of soil, treated biowaste and waste, obtained according to EN ISO 54321 (aqua regia digestion) or EN 16173 (nitric acid digestion) or EN 13656 (digestion with a hydrochloric, nitric and tetrafluoroboric or hydrofluoric acid mixture) using cold-vapour atomic absorption spectrometry (CV-AAS). The lower working range limit is at least 0,03 mg/kg (drymatter basis) depending on digestion parameters.

1.1 This European Standard establishes general principles for the execution of bored piles (see 3.2). NOTE 1 This standard covers piles or barrettes which are formed in the ground by excavation and are structural members used to transfer actions and/or limit deformations. NOTE 2 This standard covers piles with circular cross-section (see Figures 1 and A.1a)) and barrettes (see 3.3) with rectangular, T or L or any other similar cross-section (see Figure 2) concreted in a single operation. NOTE 3 In the standard the term pile is used for circular cross-section structure and the term barrette for other shapes. Both are bored piles. 1.2 This European Standard applies to bored piles (see Figure 3) with: - uniform cross-section (straight shaft); - telescopically changing shaft dimensions; - excavated base enlargements; or - excavated shaft enlargements. NOTE The shape of a pile base and of an enlargement depends on the tool used for the excavation. 1.3 This European Standard applies (see Note) to: - bored piles with a depth to width ratio ? 5; - piles (see Figures 1 and 3) with a shaft diameter 0,3 m ? D ? 3,0 m; - barrettes (see Figure 2) with the least dimension Wi ? 0,4 m, a ratio LBiB / Wi between its largest and its least dimensions ? 6 and a cross-sectional area A ? 15 m²; - piles with circular precast elements used as structural member (see Figure 7) with a least dimension DP ? 0,3 m; - barrettes with rectangular precast elements used as structural member with a least dimension WP ? 0,3 m. NOTE The standard covers a large range of diameters. For small diameter bored piles less than 450 mm, the general specification can be adapted to cater for the lack of space (e.g. minimum bars number and spacing). 1.4 This European Standard applies to piles with the following rake (see Figure 4): - n ? 4 (? ? 76°); - n ? 3 (? ? 72°) for permanently cased piles.

This European Standard establishes general principles for the execution of diaphragm walls as either retaining walls or cut-off walls. NOTE 1 This standard covers only structures constructed in a trench excavated with a support fluid or in dry conditions, where soil is removed and replaced by concrete or slurry and with wall thickness B = 40 cm. NOTE 2 Diaphragm walls can be permanent or temporary structures. NOTE 3 The following types of structure are considered: a) retaining walls: usually constructed to support the sides of an excavation in the ground. They include: 1) cast in situ concrete diaphragm walls; 2) precast concrete diaphragm walls; 3) reinforced slurry walls; b) cut-off walls: usually constructed to prevent migration of groundwater, clear or polluted, or of other contaminants present in the ground. They include: 1) slurry walls (possibly with membranes or sheet piles); 2) plastic concrete walls. NOTE 4 Walls formed shallow vertical trenches (typically excavations with a ratio of depth over thickness D/B < 5 or D < 5 m) are not covered by this standard.

 

This document applies to small craft and defines a practical degree of fire prevention and protection intended to provide enough time for occupants to escape a fire on board small craft. This document does not apply to: — the design and installation of permanently installed galley stoves and heating appliances (including components used to distribute the heat) using fuels that are liquid at atmospheric pressure on small craft, which are covered by ISO 14895; — personal watercraft; — carbon monoxide detecting systems, which are covered by ISO 12133:2021 [1]; — portable equipment containing lithium-ion batteries.

 

This document defines a practical degree of fire prevention and protection intended to provide enough time for occupants to escape a fire on board small craft. It applies to small craft having a length of the hull (LH) of up to 24 m except for personal watercraft. This document does not cover: —    the design and installation of permanently installed galley stoves and heating appliances (including components used to distribute the heat) using fuels that are liquid at atmospheric pressure on small craft, which are covered by ISO 14895:2016; —    carbon monoxide detecting systems, which are covered by ISO 12133.

 

This document describes a test method for the determination of the fracture toughness of monolithic ceramic thin plates at room temperature by the single-edge precracked plate method or the single-edge V-notch plate method. This document is intended for use with monolithic ceramics and whisker- or particulate-reinforced ceramics which are regarded as macroscopically homogeneous. It does not include continuous-fibre-reinforced ceramics composites. This document is applicable to ceramic thin plates with a thickness of 0,2 mm to =1,0 mm. The single-edge V-notch plate method can be applied to monolithic ceramics with a grain size larger than about 1 µm. The use of this method is inappropriate for yttria tetragonal zirconia polycrystal material (Y-TZP), which consists of homogeneous fine submicron grains. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch. This document is applicable for material development, material comparison, quality assurance, characterization, reliability and design data generation. The Scope clause is a mandatory element of the text. For rules on the drafting of the Scope, refer to the ISO/IEC Directives, Part 2:2018, Clause 14.

This document specifies the performance requirements, test procedures, operator proficiency, and operational requirements for a technique known as optical gas imaging (OGI).This document applies to the use of OGI cameras as part of an LDAR programme. It specifies the scope of application, performance requirements for OGI equipment and QA/QC procedures.This document focuses on LDAR programmes, applied to VOCs (including methane), but a similar approach could be applied to other compounds that have IR spectral properties that enable visualization, by adapting the selection of OGI cameras having a detector with a different bandwidth.Different types of technologies for OGI camera exist on the market, such as detectors which are either cooled or uncooled, as well as active and passive OGI cameras. However, this document focuses on the utilization of the most commonly utilized technology, the passive OGI cameras. Despite this, a similar approach could be applied to the use of active OGI cameras.
