3.13 Workmanship:
3.13.1 General.- The regulator, including all parts and accessories,
shall be constructed and finished in a thoroughly workmanlike manner.
Particular attention shall be given to neatness and thoroughness of soldering,

shall be free from backlash.
3.13.6 Cleaning. - The regulator shall be thoroughly cleaned of loose,
spattered, or excess solder, metal chips, and other foreign material after
final assembly. Burrs and sharp edges, as well as resin flash that may
crumble, shall be removed.
