1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres. NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4. 1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan. This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety. 1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having — absolute pressures ranging from 0,8 bar to 1,1 bar, — and temperatures ranging from -20 °C to +60 °C, — and maximum volume fraction of 21 % oxygen content, — and an aerodynamic energy increase of less than 25 kJ/kg. NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3. This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter. NOTE 2 Temperatures below -20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of -20 °C to +60 °C the normal ambient temperature range for the equipment is -20 °C to +40 °C unless otherwise specified and marked. 1.5 This document does not apply to: — group I fans (fans for mining); — explosion group IIC (other than hydrogen); — category 1D fans; — cooling fans or impellers on rotating electrical machines; — cooling fans or impellers on internal combustion engines, vehicles or electric motors. NOTE 3 Measures for category 1D fans are given in EN 1127 1:2019. NOTE 4 Measures for explosion group IIC (other than hydrogen) are given in EN 1127 1:2019. NOTE 5 Measures for explosion group I are given in EN ISO/IEC 80079 38:2016 and EN 1127 2:2014.

This part of EN 196 describes the method for the determination of the compressive and, optionally, the flexural strength of cement mortar. The method applies to common cements and to other cements and materials, the standards for which call up this method. It may not apply to other cement types that have, for example, a very short initial setting time. The method is used for assessing whether the compressive strength of cement is in conformity with its specification and for validation testing of a CEN Standard sand, EN 196 1, or alternative compaction equipment. This part of EN 196 describes the reference equipment and procedure and allows alternative compaction equipment and procedures to be used provided that they have been validated in accordance with the appropriate provisions in this document. In the event of a dispute, only the reference equipment and procedure are used.

 

This document gives guidance on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents. The methods can be applied to individual wood species and processed wood-based materials, including thermally and chemically modified, and water-repellent impregnated wood. Examples of wood-based materials are oriented strand boards (OSB), particle boards, fibre boards, laminated veneer lumber (LVL), and plywood. However, this document is not intended to give guidance on methods for determining and classifying the durability of wood products, coated wood, and wood polymer composites. Preservative-treated wood is not within the scope of this document, since requirements for the effectiveness of wood preservatives and durability requirements of wood treated with preservatives are regulated in several other European standards. However, this does not apply to modified wood, which is why it is included in the scope of this document. The wood-destroying agents considered in this document are: — wood-decay fungi (basidiomycete and soft-rot fungi); — beetles capable of attacking dry wood; — termites; — marine organisms capable of attacking wood in service. Data on the biological durability of the heartwood of selected wood species considered of economic importance in European countries are presented in Annex A (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability. NOTE Treatability, durability to disfiguring fungi, permeability to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex B (informative) for the classification of wood treatability with aqueous wood preservatives, Annex C (informative) for the classification of the permeability to water, and Annex D (informative) for the durability to disfiguring fungi.

 

This document specifies the apparatus and procedure for determining the effective alkali content of cements and other hydraulic binders.

This document specifies the equipment to be used, the procedures to be applied and the requirements for sampling common cement and/or its constituent materials, representative of defined lots, for testing purposes. The same equipment and procedures can be used for other types of cement or materials; in some cases, modifications to the procedure are also permitted, provided that this document and/or the modifications are referenced in the relevant product standards. The provisions of this document are only applicable when samples of constituent of common cement are: a) required for evaluating the conformity of common cement or constituent of cement at the characteristics related to common cement, to cement constituents, to the release of dangerous substances to soil and ground water of common cement, and to environmental sustainability of common cement; or b) requested for checking a delivery or a lot with a standard, the provisions of a contract or the specification in an order. This document is applicable to the sampling of powders or bulk materials, whether they are: c) contained in silos; d) contained in bags, canisters, drums or any other packages; e) transported in bulk in road vehicles, railway wagons, ships, etc. NOTE The requirements of this document can also, by agreement between the parties, be followed for acceptance inspections for all non-standardized hydraulic binders.

 

This document describes the analytical procedures used to determine the content of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A) and tetracalcium aluminoferrite (C4AF) of cement starting from a chemical analysis on cement. The method can be applied on all common cements as defined on EN 197-1. This document also describes the calculation procedures for determining of tricalcium silicate (C3S), dicalcium silicate (C2S), aluminate (C3A) and tetracalcium aluminoferrite (C4AF) in the Portland cement clinker as defined in the EN 197-1. In both cases, for cement and clinker, the calculation method is based on the Bogue method assuming each phase has a pure composition. This is a conventional method, whereby the actual mineralogical composition can differ from the results obtained using this method. For the determination of the various chemical species of clinker, cement and basic-complexing residue (BCR) described in this document, the method is indicated in the relevant clause.

 

This document describes a method for the determination of whiteness and the colour of common cements and clinkers. This method can be used to determine the whiteness of white cements defined in the EN 197-1. This document does not apply to colour measurements on cement-based formulated products or cement-based products. The method is based on the measurement of the CIE XYZ trichromatic coordinates and describes the mathematical procedure for converting these coordinates into the CIE 1976 (L*a*b*) colour space. NOTE Although the possible values of the L* parameter range from 0 to 100, this document applies to the range between 70 and 100 (photopic vision).

 

This document describes the method for determining the contribution of cement’s alkali to the alkali-silica reaction process that can occur in concrete or mortar containing aggregates potentially susceptible to alkali attack. The principle is to consider the alkalis from the insoluble part of the cement (generally associated with fly ash, for example, or pozzolans) and the alkali from the diluted part of the cement (generally associated with clinker, gypsum, granulated blast furnace slag, or limestone) [1]. This test method can be used in the framework of preventing the risk of alkali silica reaction [2].

 

This document describes two equivalent test methods for determining the glass content in Granulated blast furnace Slag (GBS) as constituent for common cement as defined on EN 197-1. Method A - Method of determining the glass content of GBS by X-ray diffraction. Method B - Method of determining the glass content of GBS by polarized optical microscopy. The glass content (or glassy/amorphous phase) in GBS is the fraction of the material that lacks a crystalline structure, having solidified rapidly from the melt in the form of amorphous glass. It is usually expressed as a percentage (wt%) of the total slag. In the absence of a product standard or a specification in the product standard, the constituent is tested at the fineness of the intended use. Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their conformity to the limit indicated in EN 197-1.

 

This document describes a test method applicable to cast test specimens for evaluating the Sulfate 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 a defined concentration of sulfate solution. The chosen test conditions are intended to accelerate external sulfate attack. This test method is appropriate in particular for CEM III/A cements and other various binders, in particular those with pozzolanic main constituents. It is adapted from the CUR - NL - Civieltechnisch Centrum Uitvoering Research en Regelgeving (Centre for Civil Engineering Research and Codes) - Recommendation 48 - Suitability test for new cements for application in concrete. This test method is listed in European Assessment Document - EAD 150004-00-0301, Annex B.

 

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.
