RECENT TRENDS IN AUTOMOTIVE IGNITION SPECIFICATIONS AND MATERIALS (SILICONE RUBBER)

Rapid growth in use of silicone rubber in ignition cables has resulted in a profusion of individual manufacturers' specifications and test methods, suggesting the need for a universal standard. Society of Automotive Engineers (SAE) J557 could be revised to encompass the new requirements in the following ways: Test procedures should be as short as practical, perhaps 1000 or 1200 hours. Performance and not construction should be specified. Obsolete tests should be eliminated. A material call-out that includes slab properties should be used to provide a starting point (this should conform with SAE J200). In testing high physical properties should not be confused with outstanding high temperature performance. Elastomers which meet table GE of SAE J200 offer the best value in high temperature performance for most applications. The principal performance criterion for ignition cable is electrical; adding both fume process silica and ground quartz as filler will increase electric strength.
