The name “Underwriter” has been largely used for a considerable time
to designate the type of pump covered by the principal features of
these specifications. While our preferences are against the use of
this word as designating any piece of apparatus objections will not
be raised at the present time to its being continued on name plates
in place of the words “National Standard,” if manufacturers so desire.
_b._ This plate must have an area of not less than one square foot, and
must be made of an alloy at least two-thirds aluminum and the remainder
zinc. The letters must be at least one-half inch in height, plain and
distinct, with their surfaces raised on a black background and buffed
off to a dead smooth finish.
The name of pump manufacturer may also be placed on this plate, if
desired.
_c._ A smaller plate of composition must be attached to steam chest
bearing the size of pump, the shop number, and the name of shop in
which the pump was built.
