It’s now been more than 30 years since I first learned about stand­ards, in the form of the Ontario Elec­tric­al Code. I was study­ing elec­tri­city and elec­tron­ics in high school, and Steve Struk, the Elec­tri­city Teach­er at Erindale Sec­ond­ary School in Mis­sissauga, intro­duced us to the rules.

Why YOU need a Product Safety Certification Strategy that Works!

How com­pli­ance efforts go wrong Cli­ents call me when they have prob­lems. They sent some product to a cer­ti­fic­a­tion body, some tests were done, and the product failed. Now what?
