This British Standard specifies requirements and test methods for the construction and performance of cables that:<\/p>\n

    \n
  1. \n

    have a thermosetting insulation of rated voltage up to and including 450\/750 V;<\/p>\n<\/li>\n

  2. \n

    emit limited amounts of smoke (see 16.6<\/b>) and corrosive gases when subjected to relevant tests compared with corresponding PVC cables conforming to BS 6004;<\/p>\n<\/li>\n

  3. \n

    are intended for electric power and lighting.<\/p>\n<\/li>\n<\/ol>\n

    The types of cable included in this British Standard are:<\/p>\n

      \n
    • \n

      thermosetting insulated and thermoplastic low smoke halogen free sheathed cable 450\/750 V single core 6181B (see Table 3);<\/p>\n<\/li>\n

    • \n

      thermosetting insulated and thermoplastic low smoke halogen free sheathed circular cables 450\/750 V, 2-core 6182B, 3-core 6183B, 4-core 6184B and 5-core 6185B (see Table 4);<\/p>\n<\/li>\n

    • \n

      thermosetting insulated and thermoplastic low smoke halogen free sheathed cables 300\/500 V single-core 6241B, flat twin 6242B, flat 3-core 6243B with circuit protective conductor (see Table 5).<\/p>\n<\/li>\n<\/ul>\n

      The insulation and other components are suitable to permit operation of the cables at a maximum sustained conductor temperature of 90 \u00b0C and for a maximum short-circuit conductor temperature of 250 \u00b0C (for a maximum period of 5 s).<\/p>\n

      \n

      NOTE 1 Limitation on the temperature of the cables may be imposed in situations where they could be touched, or where they could touch other materials.<\/p>\n<\/blockquote>\n

      \n

      NOTE 2 In installations that include wiring accessories, junction boxes and consumer units etc., the performance of these accessories should be taken into account in deciding the maximum operating temperature of the cable.<\/p>\n<\/blockquote>\n

      \n

      NOTE 3 Annex A provides a guide to the cross-referencing of the traditional United Kingdom Cable Codes (formerly known as the CMA codes) and harmonized CENELEC codes. Furthermore, Annex B gives information on the traditional UK cables transferred to BS EN 50525.<\/p>\n<\/blockquote>\n

      \n

      NOTE 4 Annex C gives guidance on the use of the cables specified in this British Standard.<\/p>\n<\/blockquote>\n

      \n

      NOTE 5 Annex D gives the compatibility test method.<\/p>\n<\/blockquote>\n

      \n

      NOTE 6 Annex E gives the voltage withstand test.<\/p>\n<\/blockquote>\n

      \n

      NOTE 7 Annex F gives notes on type tests.<\/p>\n<\/blockquote>\n

      \n

      NOTE 8 In this British Standard, corrosive (and acid) gases are defined as those that are determined as HCl.<\/p>\n<\/blockquote>\n
