UL Standard for Safety Standby Batteries
|Publication Date:||26 December 1996|
These requirements cover instrument batteries, enclosed batteries, emergency lighting and power batteries and uninterruptible power supply batteries.
These requirements only address potential risks unique to the utilization of a battery supply in a product. Products employing a battery supply shall comply with the basic requirements contained in this standard applicable to the type of product and its intended use.
These requirements do not cover risks that may be unique to certain cell chemistries, such as the fire and explosion risks of lithium batteries. Additional investigations are required to evaluate such risks.
The investigation of a family or group of batteries may be based on the investigation of batteries representative of the family or group.
A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard cannot be judged to comply with this standard. Where considered appropriate, revision of requirements shall be proposed and adopted in conformance with methods employed for development, revision, and implementation of this standard.
