25、ation. Two test schedules are provided: A basic test schedule applies to compression mount connections which conform to all of the requirements given in Clause 4. A full test schedule applies to compression mount connections which are part of a new component and have already passed the basic test sc

26、hedule or to connections of the same kind which do not fully comply with the requirements of Clause 4. Requirements given in Clause 4 are derived from experience with successful applications of such compression mount connections. IEC Guide 109 advocates the need to minimize the impact of a product o

27、n the natural environment throughout the product life cycle. It is understood that some of the materials permitted in this standard may have a negative environmental impact. As technological advances lead to acceptable alternatives for these materials, they will be eliminated from the standard. BS E

29、equipments and in other electronic devices employing similar techniques. Information on materials and data from industrial experience are included in addition to the test procedures to provide electrically stable connections under prescribed environmental conditions. The object of this part of IEC 6

30、0352 is to determine the suitability of compression mount connections under specified electrical, mechanical and atmospheric conditions and to provide a means of comparing test results when the tools used to make the connectors are of different designs or manufacture. 2 Normative references The foll
