Very well stated Rich,
(see below) It puts the finger on the real problem with what i call "testimonial certification" . It's the process were manufacturers stop thinking about safety as soon as the UL (or other respected test house) has allowed to use their safety mark. The test house however is hired to perform the certification process test according to applicable standards which as result of international standardization process must cover a very wide range of products in one manuscript. Therefore i want to draw your attention again to the European system of Safety Directives, specifying safety in terms of generic safety requirements (so-called essential requirements) and make the manufacturer sign for it's liability using the DoC. The safety of the product has to be proved to the manufacturer in such a way that he can feel confidant about it's declaration. Therefore he will need to actively seek an suitable standard or any other test suite that covers his liability, and this change of what manufacturers ask a test house stimulate test houses to research beyond the strict letter of the standard. The process shown in the ce marking system has the best of two worlds: - direct liability of the manufacturer by signing DoC - usage of international standards not to prove but give assumption of safety only (this requires the manufacturer to go beyond standards if he can suspect additional dangers such as food stucking into toasters) - self certification to reduce the costs of the approval process. That this process is more stringent then UL VDE or KEMA SEMCO etc testing is shown by f.a. filter manufacturers grouping together in searching to exclude their components from electrical safety ce marking, and preferring the route to hire many international test houses (including annual payments) above the free process of self certification but with inceased liability.

While I am notorious as a "UL-basher," I think the focus of this article is misplaced. This article presumes that UL puts the safety into products. Unfortunately, many manufacturers also believe that UL puts the safety into their products. Manufacturers, not UL, are responsible for the safety of their products. UL is a certifier. UL certifies that the product complies with the requirements published in a standard.
