1、Subject 1012May 1, 2009SUMMARY OF TOPICSThe following changes in requirements to the Standard for Power Units Other Than Class 2, UL1012, are being proposed:1. New requirements for batteries with integral chargers2. New requirements for power units for installation in air-handling spacesSTP BALLOTS
2、& COMMENTS DUE: JUNE 15, 2009For your convenience in review, proposed additions to existing requirements are shown underlined andproposed deletions are shown lined-out.1. New requirements for batteries with integral chargersRATIONALEProposal submitted by: Kent Donohue, Underwriters LaboratoriesUL pr
3、oposes new requirements for batteries with integral chargers. The proposal clarifies requirements applicable to batteries with integral chargers, and includes new requirements applicable to units witha solar cell feature.PROPOSALRECHARGEABLE BATTERIES WITH INTEGRAL CHARGERS92 Scope92.1 These require
4、ments supplement and in some cases modify the requirements of Sections 7 61. These requirements apply to indoor use, household, and commercial rechargeable battery packs (RBPs)of the alternating current supplied type, solar cell supplied type, or combination supplied type.92.2 These requirements do
5、not apply to a rechargeable battery for recharging from a separable batterycharger. Requirements for this type of rechargeable battery are specified in the Standard for Householdand Commercial Batteries, UL 2054.92.3 These requirements do not apply to a rechargeable battery intended for use in unint
6、erruptible powersupply applications. Requirements for this type of rechargeable battery are specified in the Standard forUninterruptible Power Supply Equipment, UL 1778.SUBJECT 1012-2-MAY 1, 200992.4 These requirements do not apply to a rechargeable battery with an integral load, such as arechargeab
7、le night light, rechargeable flashlight, a rechargeable shaver, a rechargeable screwdriver, andthe like. Requirements for these types of products are specified in other Standards appropriate to theintended use.93 Glossary93.1 For the purpose of the requirements in Sections 92 98, the following defin
