4.1 The purpose of this test method is to obtain the diffuse light transmittance factor of both flat and corrugated translucent building panels by the use of simple apparatus and by employing as a light source a combination of fluorescent tubes whose energy distribution closely...
5.1 This test method provides a standard method, by the use of X-ray fluorescence (XRF) or isotope measuring instruments, for "on-line" determination of the weight [mass] of coatings on steel sheet produced on continuous production lines, for comparison with specification requirements, and for...
Introduction and Background A number of years ago, third-party safety agencies such as UL, CSA, and ESA1 reported complaints from consumers regarding the failure modes of self-ballasted compact fluorescent lamps (SBCFL). Media coverage at the time portrayed such complaints as indicative of...
