of manufacturer, heat lot number, size, weight, and specification material type
on each container or reel/spool.
for Contractors performing weld operations for JPL:
(a) Prior to usage and when required by process or filler metal
specification, applicable chemical, mechanical, weldability,
etc., properties must be verified through tests on each shipment or lot (heat
