This European Standard describes the test methods for binders for floor screeds based on calcium sulphate specified in prEN 13454 1. This European Standard describes the test methods for factory made mixtures for floor screeds based on calcium sulphate specified in EN 13813. This European Standard describes reference test methods. If other than these methods and conditions are used, it is necessary to show that they give results equivalent to those given by the reference methods. In the event of a dispute, only the reference test method is used.

This document applies to binders made of calcium sulphate used for the manufacture of floor screeds for interior use in buildings. It also includes requirements for factory made mixtures made of calcium sulphate used for the manufacture of floor screeds which are given in EN 13813. This document does not cover the application of floor screeds. Floor screeds made with products covered by this document can contribute to thermal and sound insulation and fire protection of the floor.

This European Standard specifies requirements for roofing and cladding products used for assembly into coverings for wall claddings, linings and pitched roofs, made from aluminium sheet with or without additional surface treatment (organic coating or anodising). The standard establishes general characteristics, definitions and labelling of the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions. Products can be prefabricated or semi-formed products as well as strip, coil and sheet for on-site-formed applications (e.g. standing seam roofs). The standard applies to all discontinuously laid and fully supported roofing and cladding products made of aluminium sheets. No requirements for supporting construction, design of roof system and execution of connections and flashings are included. The standard does not apply to self-supporting aluminium sheets that are covered by EN 508-2.

This document specifies the testing instruments and procedure for filtration efficiency of flat sheet filter media against airborne nanoparticles in the 20 – 500 nm range.

This European Standard defines Product Category Rules (PCR) providing guidelines and rules for developing a type III EPD for ceramic tiles produced by extrusion and dry-pressing techniques, mainly used for internal and/or external floorings and walls coverings and façade cladding. These PCR specify the calculation rules in accordance with EN 15804 for the Life Cycle Assessment (LCA) of ceramic tiles for developing an EPD, as well as the requirements on the background of the LCA. These PCR: - define the parameters to be declared and the way in which they are collated and reported; - describe which stages of ceramic tiles’s life cycle are considered in the EPD and which processes are to be included in the life cycle stages; - defines rule for the development of scenarios; - include the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD, including the specification of the data quality to be applied; - include the rules for reporting predetermined, environmental and health information, that is not covered by LCA for a ceramic tile, construction process and construction service where necessary; - define the conditions under which ceramic tiles can be compared based on the information provided by EPD (see 5.3). The EPD developed using these PCR will contain data from the product stages (A1-A3). Optionally, the manufacturer can include all modules of the product’s life cycle stages (construction process, use, and end of life) (A4-C4), using the scenarios described in 7.3 when primary data are not available. The results of these stages shall be shown individually (without being added together). Therefore, these PCR cover: - EPD cradle-to-gate (only the product stage is considered); - EPD cradle-to-grave (the whole life cycle of ceramic tiles is considered). In these type of EPD module D may be included. After verification an EPD is valid for a 5 year period from the date of issue, after which it shall be reviewed and verified.

This European Standard specifies design, performance requirements and the test methods for WC and urinal flushing cisterns with flushing mechanism, inlet valve and overflow. This document covers flushing cisterns designed to be connected to drinking water installations inside buildings. This standard does not cover automatic valveless siphon flushing cisterns for flushing urinals. NOTE Flushing cisterns for one-piece WCs and close-coupled suites are covered by EN 997.

This European Standard specifies two procedures for sampling fresh concrete, by composite sampling and by spot sampling. NOTE The requirement for remixing the sample before tests on the fresh concrete, or before making test specimens, is included in the relevant standards. When mixing and sampling of concrete is done in a laboratory, different procedures may be required. Additionally, this standard lists common apparatus mentioned in two or more standards of EN 12350 series and EN 12390-2.

This European standard specifies a method for determining the consistence of fresh concrete by the slump test. The slump test is sensitive to changes in the consistence of concrete, which correspond to slumps between 10 mm and 210 mm. Beyond these extremes the measurement of slump can be unsuitable and other methods of determining the consistency should be considered. If the slump continues to change over a period of 1 min after withdrawing of the cone, the slump test is not suitable as a measure of consistence. The test is not suitable when the declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) is greater than 40 mm.

This European standard specifies a method for determining the consistence of fresh concrete by determining the degree of compactability. The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 63 mm. If the degree of compactability is less than 1,04 or more than 1,46, the concrete has a consistence for which the degree of compactability test is not suitable.

This European standard specifies a method for determining the flow of fresh concrete. It is not applicable to self-compacting concrete, foamed concrete, no-fines concrete, or for concrete having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) of greater than 63 mm. NOTE The flow test is sensitive to changes in the consistency of concrete, which correspond to flow values between 340 mm and 620 mm. Beyond these extremes the flow table test may be unsuitable and other methods of determining the consistence should be considered.

This European Standard specifies methods for making and curing test specimens for strength tests. It covers the preparation and filling of moulds, compaction of the concrete, levelling the surface, curing of test specimens and transporting test specimens.

This European Standard specifies the procedure for determining the slump-flow and t500 time for selfcompacting concrete. The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 40 mm.

This European standard specifies a method for determining the density of compacted fresh concrete both in the laboratory and in the field. NOTE It may not be applicable to very stiff concrete which cannot be compacted by normal vibration.
