4、willnot Each enclosure, at the completion of all drawing and.fabrication opera- distort nor leak when subjected to prescribed impact (see note 37). tions, shall be stress relieved by being uniformly heated to a temper- ature suitable for the material used. Stress relief shall be such as to reduce re

5、sidual stress from fabrication, to a minimum. However, enclo- sures.which are oven brazed as part of their fabrication process do not require additional heat treating for stress relief. The words stress relieved shall be stamped on the outside bottom sur- face of each complete unit in l/4-inch high

Folded watertight enclosures: Gasket shall be made in four pieces, Long dimension pieces shall be installed first and shall fit tightly throughout the groove and at the ends. Short dimension pieces shall then be fitted to butt tightly against the

9、 free ends of the long pieces. Gasket joints shall be made tight with rubber cement. Gaskets shall not be cemented along the qrooves. Before shirment, qasket shall be relieved of pressure. 15. Forded submersible enclosuresr Gasket length shall be such as to completely fill the retainer groove with t

10、ension. Special care shall be exercised in cutting the single bevel joint to insure smooth faces. These faces shall be securely joined by meanS.of rubber cement. At assembly with enclosure the bevel joint shall be located on a straight side. The gasket shall not be cemented in the retainer groove. B

11、efore shipment, gasket shall be relieved of pressure.
