4.3.3 Dent – A dimple or concavity in the surface caused by a blunt force.
4.3.4 Bend – A crease in the metal that extends to an edge of the surface
distorting it from its intended shape.
5.0 Defect Accept / Reject Criteria:
5.1 Collar:
5.1.1 Scratches or Scuff marks: Cannot expose base metal. No more than one
allowable.
5.1.2 Dent: No greater than .500” at greatest diameter point. No more than one
allowable.
5.1.3 Bent: Reject
5.2 Valve, Knob:
5.2.1 Dent: Reject
5.2.2 Bent: Reject
5.2.3 Missing or damaged Dust Cap: Substitute with a non-defective replacement

surface = one.
5.3.1.2 “B” Surface: Acceptable as long as scratches and scuffs do not
expose base metal and dents are not present.
5.3.2 Dent: Reject

surface = two.
5.4.2 Dent: No greater than .500” at greatest diameter point. No more than one
allowable. Dent should not inhibit proper alignment when attached to the
tank support bracket.
5.4.3 Bent: Reject
5.5 Warning Label (OPD Requirement):
5.5.1 Tanks should be visibly affixed with an Overfill Protection Devise (OPD)
