    hello,

    I have a small battery charger unit. In theback there is a logo ; UL
    in a circle. I found on google that it is a standard for safetly. But
    I saw there are many levels for different tools. Like UL 325, UL 745.
    what does all this mean. Mine does not have a number beside it. in
    which category does it fall in ?

    k

    ** Groper alert !

    ** The UL logo is not any standard.


    ** They are standards for garage doors and portable power tools.


    ** The UL logo just means the device bearing it has been checked to comply
    with the appropriate standards for what it is.

    For example - glass tube fuses often bear the UL logo.

    Search the above database for "battery charger" and find the company
    name. Then click on the appropriate file.

    There are many different UL standards, all of which deal with different
    products, different environments, and aspects of those products.

    The UL standard dealing with battery chargers is UL-1236. Amongst other
    things, the standard describes the requirements that the charger must
    meet with regards to safety aspects. In this context, safety aspects
    refer to things such as how how any portions of the enclosure that the
    user may come in contact with, and how resilient the device is to being
    dropped, etc.
