Bituminiai mišiniai. Bandymo metodai. 18 dalis. Rišiklio nutekėjimas

This document describes two test methods: - basket method (see Clause 4); - beaker method (see Clause 5). The basket method describes a method for determining binder drainage of bituminous mixtures. This method directly measures binder drainage, but when carried out on bituminous mixtures with fibres or mixtures whose mortar content is higher than in porous asphalt some clogging of the holes in the drainage baskets can occur, limiting the drainage of the binder. The basket method can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified. The beaker method describes a method for determining binder drainage of bituminous mixtures. It is applicable to asphalt materials that are not porous asphalt or for porous asphalt incorporating fibres. It can be used either for determining the binder drainage for different binder content, or with a single binder content, eliminating the successive repetitions. It also enables the effects of varying fine aggregate types or including any anti-draining additive to be quantified.

Signalų perdavimas žemosios įtampos elektrinėje įrangoje nuo 3 kHz iki 526,5 kHz dažnių srityje. 1 dalis. Bendrieji reikalavimai, dažnių juostos ir elektromagnetiniai trikdžiai

This document applies to mains communicating equipment (MCE) using signals in the frequency range 3 kHz to 526,5 kHz to transmit information on low voltage electrical systems, either on the public electricity distribution network, within installations in consumers’ premises which are connected to the public electricity distribution network or within installations separated from the public electricity distribution network. NOTE 1 Installations separated from the public electricity distribution network can be operated in DC. Typical applications include MCS communication between photovoltaic panels and inverters over a DC bus in photovoltaic power generating system. Requirements specific to such installations are given in Annex G. It specifies the frequency bands allocated to the different applications as well as conducted and radiated emission limits, including conducted emission limits for the transmitter output signal voltage in the operating band. It also specifies the required measurement methods. It does not specify modulation methods, coding methods or functional features (except those for the prevention of mutual interference). Environmental requirements and tests are not included. NOTE 2 Compliance with this document does not imply permission to establish communication with locations outside the consumer’s installation or with other consumers through the public electricity distribution network where this would not otherwise be allowed. MCE can fall into one of the following categories: a) MCE implementing transmission or reception of information on low voltage electrical systems as the sole function. General requirements, frequency band allocation and emission limits applicable to such equipment are entirely covered by this document. b) MCE being equipment within the scope of other standards, integrating mains communication as one of their functions. In this case, only the general requirements, frequency band allocation and emission limits for the mains communication function of such equipment are covered by this document. Requirements for all other available functions of this equipment are covered by the relevant product standard. This document aims at contributing to EMC by limiting the mutual influence of different MCE or different mains communicating systems (MCS) operated in the same environment. In addition, this document is intended to limit interference caused by MCE signal transmission to general electrical equipment.

Žaislų sauga. 20 dalis. Žaislų, kuriuose yra pasiekiamos vandeninės terpės, mikrobiologinė sauga

This document specifies microbiological cleanliness and preservative efficacy requirements for accessible aqueous media in toys. The requirements in this document apply to all toys that are, contain or are supplied with accessible aqueous materials (e.g. paste, putty, liquid or gel). The cleanliness and preservation effectiveness requirements are applicable to a toy as it is initially received by the consumer, in an unopened and undamaged container. This document does not apply to a toy that has been used, has had its packaging opened or is otherwise compromised in a way that would introduce microbiological contamination. This document does not cover products and samples which are post-consumer use, since the microbiological limits are inappropriate given there is no way to establish what conditions the toys have been subject to before testing. The following are specifically excluded from the scope of this document: - materials that are inaccessible during normal use or reasonably foreseeable abuse; - food; - cosmetics; - components of toys covered by EN 71-13 where; - the component is in scope of the Cosmetic Products Regulation (i.e. Regulation (EC) No 1223/2009 [13]; and - the component comprises only recognized food flavours and food ingredients (see relevant legislation, for example Regulation (EC) No 178/2002 [16] ("general food law"), Regulation (EC) No 1334/2008 [15] (flavours), Regulation (EC) No 1333/2008 [14], Commission Regulation (EU) No 231/2012 [18] (food additives) and Regulation (EU) No 1169/2011 (food information to consumers)[17]); - experimental sets covered by EN 71-4. NOTE Play cosmetics, that are only for use on the toy (e.g. makeup products only for a doll), are not excluded.

This document describes the test and assessment procedure for determining the contribution of reactive fire protection systems to the fire resistance of solid steel bars used as tension members, when exposed to the standard temperature/time curve specified in EN 1363-1. In special circumstances, where specified in National Building Regulations, there can be a need to subject reactive fire protection systems to a slow heating curve (smouldering fire) as defined in EN 1363-2. The corresponding test and assessment procedure are described in Annex E. The fire protection performance is determined by testing mechanically loaded steel bars in horizontal orientation. Information regarding the testing of additional unloaded specimens is given to assess the influence of the bar orientation and smouldering fire behaviour. The principles of the testing and assessment procedure can also be applied for other section shapes such as angles, channels and flats. This document does not include steel bars used as reinforcement in concrete construction. The document is applicable to steel bars up to a maximum diameter of 130 mm. In the case of rectangular bars, the maximum edge length shall be limited to 130 mm with a maximum aspect ratio of 2:1 against the shorter edge length. The test programme and the assessment are designed to cover: - a range of valid fire protection classification periods; - a range of thickness of the applied reactive fire protection system; - a range of steel bar dimensions and profiles; - a range of specified design temperatures; - a range of load utilisation factors in case of fire; - a range of bar orientation. This document also provides the assessment procedure, which prescribes how the analysis of the test data shall be made and gives guidance on the procedures by which interpolation shall be undertaken. The assessment procedure is used to establish: a) on the basis of data derived from mechanically loaded testing steel bar, any practical constraints on the use of the reactive fire protection system under fire test conditions (the physical performance); b) on the basis of the temperature data derived from testing steel bar the thermal properties of the reactive fire protection system (the thermal performance). The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel types and sizes over the range of thicknesses of the applied reactive fire protection system tested.
