Under normal ambient conditions, after High Temperature Test, Low Temperature Test, Temperature Varying Test, and Damp-heat Test, the insulation resistance, between any two independent contacts, and between any contact and metal work, should be greater than 1000 mIc under 500V DC.
Dielectric Strength
Under normal ambient conditions, after High Temperature Test, Low Temperature Test, Temperature Varying Test, and Damp-heat Test, the dielectric strength, between any two independent contacts, and between any contact and metal work, should be able to withstand an AC voltage of 1000V (virtual value) at 45~60 Hz for 1 minute without evidence of spark-over and arc.
Contact resistance between reeds: initial value a?? 7 mIc
Contact resistance between conductor and reed: initial value a?? 3 mIc
Pulling force: > 25N |
