2. SUMMARY OF TESTING
2.1. Initi al Exami nation of Product - All Test Groups
Al l speci mens submitted for testing were represent ative of normal production lots. Product Assur ance
i ssued a Certificate of Confor mance. Where specified, speci mens were visually examined and no
evidence of physical damage detri mental to product performance was observed.
2.2. Contact Resistance - Test Groups 1, 2, 3, 5, 6, 8 and 10
Al l termination resistance measurements taken at 100 milliamperes maximum and 20 millivolts
maximum open circuit voltage were less than 20 milliohms
