1.1This document specifies the constructional and functional requirements and methods for testing of devices and accessories needed for the reliable and safe initiation of detonators and shock tubes, under normal working conditions. It covers the following six types of equipment:¾blasting machines for initiating electric detonators;¾blasting machine checkers;¾initiating circuit field testers;¾shot firing cables for use with electric blasting machines;¾detonator connecting wires;¾shock tube initiators for non-electric systems.1.2Equipment indented only for use indoors is excluded from the environmental testing in Annex B.1.3Blasting machines for use with electronic detonators and magnetically coupled detonators are outside the scope of this document.NOTEThis document does not meet all of the requirements of all relevant European Directives, such as the ATEX Directive 94/9/EC and the low voltage Directive 73/23/EEC. For example, EN 61010 (Safety requirements for electrical equipment for measurement, control and laboratory use) might also be relevant for some devices and accessories described in this document.
