The applicable requirements of <\/p>\n<p>IEC 60079-0<\/p>\n<p>UL 60079-0<\/p>\n<p> are identified by the clause title which is normative. This document was written against the specific requirements of <\/p>\n<p>IEC 60079-0<\/p>\n<p>UL 60079-0<\/p>\n<p> (ed. 7.0). The clause numbers for the previous edition are shown for information only. This is to enable the general requirements of <\/p>\n<p>IEC 60079-0<\/p>\n<p>UL 60079-0<\/p>\n<p> (ed. 6.0) to be used where necessary with <\/p>\n<p>this part of IEC 60079-0<\/p>\n<p>document<\/p>\n<p>. Where there is a conflict between requirements, the later edition requirements take precedence.<\/p>\n<\/p>\n<\/p>\n<p>NOTE 2 A shaded row in the above table indicates that this is a clause heading. In cases where the applicability is the same for all of the sub-clauses the \u2018Applies\u2019 or \u2018Excluded\u2019 is listed in the heading row and the sub-clauses are not expanded. Where the application of the individual sub-clauses may be different, these are expanded in the above table and the applicability for each is listed.<\/p>\n<\/p>\n<\/p>\n<p>NOTE 3 A non-incendive component is limited in use to the particular circuit for which it has been shown to be non-ignition capable and, therefore, cannot be separately assessed as complying with this standard.<\/p>\n<\/p>\n<\/p>\n<\/p>\n<\/p>\n<p> Under preparation.
