I am wanting to find standards covering immunity, emission, and safety standards for 4-20 mA industrial process monitoring loops. I have the technical standard ANSI/ISA-S50.1-1982 (R1992) which contains the standards about how the loop works (current levels, resistances, etc), but the standard doesn't mention anything about immunity, emissions, insulation breakdown and other safety tests, etc. Don Borowski Schweitzer Engineering Labs Pullman, WA ---------------------------------------------------------- This e-mail may contain SEL confidential information.
