23、 BSI ? INTRODUCTION This part of IEC 60352 includes requirements, tests and practical guidance information. Two test schedules are provided. a) The basic test schedule applies to spring-clamp connections which conform to all require- ments of clause 4. These requirements are derived from experience
24、with successful applications of such spring-clamp connections. b) The full test schedule applies to spring-clamp connections which do not fully conform to all requirements of clause 4, for example which are manufactured using materials or finishes not included in clause 4. This approach permits cost
