Special Process Requirements
Special processes performed on products for PneuDraulics purchase orders must be performed by sources holding a current Nadcap certification for the process. This includes not only processing performed in-house by the holder of the PneuDraulics purchase order, but also any processing sub-contracted by them to others.
Special processes are defined as:
|Special Process Category
||Soldering to a MIL or customer-controlled specification, welding and brazing
(Commercial grade electrical soldering is specifically excluded)
|Finishes / Surface Treatment
||Plating, passivation and chem-film
|Thermal / Heat Treatment
||Aluminum, steel, stress relief, heat treat, aging, etc.
|Nondestructive Testing (NDT)
||Ultrasonic, magnetic particle, radiography, dye penetrant, etc.
Excluded from this requirement are special processes performed on:
Supplier-designed items and materials produced to an industry standard
(e.g. no PneuDraulics drawing other than an SCD is applicable, such as
for catalog or other off-the-shelf items)
- Raw materials (metal stock).
The Nadcap listing of certified sources is currently available at
A registered account is required and procedures to obtain it are available on that site.
