Bl This standard establishes the conditions that small-power, universal, direct current electric motors must meet. B-2 This standard applies in its entirety to motors with a power between 95 and 560 W inclusive. For motors with a power less than 95W, only the requirements relating to dielectric qualities (Paragraphs E-4/5) and heating (Paragraphs E-12/14) will apply for now. B-3 This standard only includes motors in which class Al, A-2 or B insulation is used. (Paragraphs Cl 1/13).
