Required dimensions are expressed in US units first and the SI
(metric) equivalents given in parentheses are approximate. All
values which do not carry specific tolerances or are not marked
maximum or minimum shall have the following tolerances: Linear
dimensions shall be ± 1/16 in (1.6 mm). Pounds or pound force shall
be ± 5%. Angular measurements shall be ± 4 degrees. Voltage
measurements shall be + 5 percent. Temperature
measurements shall be + 4 degrees F (+2 degrees
Compliance with the requirements of this standard shall be
accomplished through factory settings or field adjustments as
Operators used on labeled fire door assemblies shall be listed
