As far as safety goes, you'll need to meet Hazardous location standards. The UL standards numbers vary by protection method used, UL 1203, 913, 1604, 2279, NFPA 496. Canada has similar requirements, in CSA 30, 157, 213, and E79, as well as incorporating NFPA 496. For the IECEx scheme, see IEC 60079 series, as well as some product specific Class 1, Zone 1 & 2 requirements in IEC 62086-1. Europe has EN 50284, 50015 through 50021, 50028. As far as EMC goes, When in doubt, err on the overkill side, especially when testing something that, when it fails, could lead to a news flash (pardon the pun), and nasty injuries. And of course, anything that disturbs the gasoline flow (even at one pump) raises the cost of gas by at least a nickel/gallon nationwide. (convert at will for petrol) Another fault to look for is billing - make sure the flow meter and billing amounts aren't disturbed. Or if they are, let me know which brand pump it is, and what frequency and power level stops/slows the billing. (for scientific purposes only, of course) Sam From: [email protected] [mailto:[email protected]]On Behalf Of GARY MCINTURFF Sent: Friday, September 05, 2003 5:44 PM To: emc-pstc Subject: Anybody out there gasoline (okay Petrol if I must) pumps for service stations?
