25、not covered in IEC 62013-1, but which are nevertheless important for the safety and working conditions of the user. It may also be applied to caplights for use in mines not likely to be endangered by firedamp. When this part of the standard is used as a “stand-alone“ document for non-gassy mines, an
26、y relevent constructional requirements should be the subject of agreement between the supplier and the user and, where possible, be as described in IEC 62013-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of
27、 this part of IEC 62013. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However parties to agreements based on this part of IEC 62013 are encouraged to investigate the possibility of applying the most recent editions of the normative document
28、s indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IEC and ISO maintain registers of currently valid International Standards.

35、itted with two lamps or filaments, each of which is capable of being the main source, the manufacturer shall designate which of these shall be the main source and which the auxiliary source; otherwise, both sources shall meet the requirements for the main source. 5.1.3 Filament lamps for main and au
36、xiliary sources shall comply with IEC 60983. Where the relevant data sheet is not given in IEC 60983, an equivalent shall be provided by the caplight manufacturer. 5.2 Light source holder The holder for the main light source shall be capable of locating and retaining it securely in a focused positio
37、n with respect to the reflector profile in accordance with 5.6. 5.3 Illumination cut-off angle The luminous intensity from the main light source in a fully assembled headpiece shall not be less than 1 cd over a solid angle of 120 when tested in accordance with 8.1.

It shall be rated at a minimum 1 W. 5.6 Focus The main light source shall be
40、 focused, or capable of being focused, so that the light pattern is not impaired by distortion. 6 Reliability 6.1 Lamp life The life of the main and auxiliary lamps shall comply with the values given in the data sheets in 5.1.3 when tested in accordance with 8.3. The minimum life shall be not less t
41、han 200 h for the main source and 50 h for the auxiliary source. 6.2 Battery life (charge/discharge cycles) It is not possible to specify a cyclic life for the battery due to the multiplicity of battery types, charging regimes and conditions of use. It is therefore important that the manufacturer pr
42、ovides instructions to the user on the recharge time and routine checks which are necessary to ensure that the battery is capable of performing its intended duties during the actual working period. See clause 9 and annex A. NOTE The choice of battery charging equipment will depend on the time availa
43、ble between successive actual working periods. When the recharge time is insufficient to fully recharge the battery, the manufacturer may need to advise the user to provide additional caplights. 6.3 Caplight useful working period The manufacturer shall declare the useful working period of the caplig
44、ht when new, taking into account the current drawn by the main light source and, if appropriate, the average current drawn by any accessories during that period. The test requirements are given in 8.2. 6.4 Durability 6.4.1 Fasteners and connectors Fasteners and connectors shall be designed so that t

47、ss of the battery and container shall not exceed 2 750 g and the total mass of the complete caplight assembly shall not exceed 3 250 g. 7.2 Ease of operation The switch shall be easily accessible to the wearer with the caplight in the position normally worn. The switch shall be positive in action an
48、d shall have an “off“ position and such “on“ positions as are appropriate. NOTE The switch should be operable while wearing protective gloves. 7.3 Maintainability The caplight shall be constructed in such a manner that user replaceable parts are easily accessible after operation or removal of any sp
49、ecial fasteners. If necessitated by the battery design, means shall be provided for initial filling, subsequent topping up and changing of electrolyte. 8 Type tests 8.1 Illumination cut-off angle The following test shall be carried out in a darkened room where any reflected light will not influence the results, at a temperature of 20 C ? 5 C. Disconnect the headpiece and cable from the battery and connect it to a d.c. power source with a residual ripple not greater than 3 mV and capable of maintaining the voltage within
