RE: CEN standard scopes/abstracts

While certainly not a "failsafe" method to determine the scope for all standards, the UL web site lists the scope clauses for all of its stds. Stds that are dupes of IEC stds will probably(?) not differ. I have also slipped in the lazy habit of calling my local agency engineer for scopes and/or to

CEN standard scopes/abstracts

I've been trying to be ascertain the scope of certain standards to establish applicability to a product. IEC/CENELEC standards' abstracts are (generally) relatively easy to get at the IEC web store; ISO is spotty, but standards' scopes are often available and there's at least a place holder on t

SV: Security and Alarm Systems

The EU regime within fire alarm systems are beginning to get harmonized through the Construction Product Directive (CPD). At least heat and smoke detectors (transition period to 2005), but the fire alarm panel / central unit is still many years away. The essential standard series is EN54 (published

RE: Insulation enhancement?

Bill, Most standards, including IEC 60664-3, only recognize conformal coating for pollution control. Pollution Degree 1, by itself often buys you a smaller spacing. In to use a coating as insulation control and still smaller spacings, you need to use a qualified encapsulant. -doug Douglas

RE: RFID Demo Equipment and the FCC / Industry Canada

John, one of the issues is when does something stop being a component/module that is not required to be tested and becomes a product that must be tested? The module/device does not have a complete enclosure, nor did it include power supplies, but it did include an antenna. The device with the ante

RE: Insulation enhancement?

For UL, the conformal coat is considered an Insulation System, and shall be a r/c. There are both mechanical and electrical Type Tests for this application as insulation. Also, the application process must be controlled, documented, and audited. If you can convince the examining engineer that the
