MIL-HDBK-1110
Government agencies cannot purchase a sole source product, unless
it can be shown to be uniquely differentiated from other
products. Sometimes, a qualified products list can be used or
suggested suppliers of coatings for a particular specification,
for which good performance data are available. Specifying "Brand
X or equal" is dangerous, because there is no specific definition
of "equal" or procedure to determine such equality. Also
dangerous is to describe a product by its composition and/or
performance. These are sometimes done to procure a particular
product without calling out its name. Standard colors available
in the particular specification or commercial product should be
specified. FED-STD-595 provides a large number of color chips
for which many specification coatings are available. A fandeck
of these chips is also available from the General Services
Administration (GSA). It is better to use these standards than
to refer to a particular supplier's color code or name.
Whatever the method of specifying products, it is
always best to require that products for a multiple-coat system
be procured from the same supplier, who recommends their use
together. This will avoid compatibility problems and limit any
liability to one supplier.

Execution Part. The execution part of the
specification describes the use of the materials in the products
part. Because painting may be only a small part of a
construction project, it must be coordinated with the other
sections. This will permit surface preparation and coating
application under suitable conditions and without delays or other
Much information of the execution of a specification
may be found in drawings that form a part of the specification.
To prevent problems resulting from variations between
descriptions in the drawings and the body of the specification,
requirements in the body should be stated as preempting those in
drawings. They should not repeat requirements in the body of the
contract to avoid differences.
8.3.3.1
Work Conditions. This portion of the execution part
describes the weather conditions under which work is permitted.
If priming of steel is delayed by the weather or other reason, it
will be necessary to reblast the steel to remove any flash
rusting that has occurred during the delay.
The air temperature at the time of coating application
should be in the supplier's listed acceptable range. The
temperature should be at least 5 degrees above the dew point, and
