Page v of vi

BUYER – The company for whom the VENDOR is performing work or services.

COMMERCIAL QUALITY ASSURANCE (CQA) - Level of controls for those items, services, orprocesses where, based on an evaluation of risk or nuclear safety, no additional quality controlsbeyond the providers published or stated attributes of the item, service, or process is required.

DESIGN CHANGE – Within the context of this specification, a DESIGN CHANGE is technicallyequivalent to a SUBSTITUTION (see SUBSTITUTION definition below). However, the termDESIGN CHANGE may be used to refer to more significant changes to the design compared to asimple substitution.

DEVIATION – Any departure from the requirements contained in the purchase order andspecification which VENDOR proposes to incorporate if approved by BUYER.

ENHANCED QUALITY ASSURANCE (EQA) - Level of controls for those items, services, orprocesses where, based on an evaluation of risk or nuclear safety, additional controls beyond theproviders published or stated attributes of the item, service, or process are needed to verifycritical attributes.

FULL QUALITY ASSURANCE (FQA) - Level of controls applied for items services, or processesthat are commensurate with the controls invoked under ASME NQA-1 or other appropriatenational consensus standard.

HANDLING - The movement or transportation of items following receipt from offsite/ projectlocations. This includes movement within storage areas and movement/transportation fromreceipt or storage areas to field locations. Handling requirements include the need for specialhandling tools and equipment, restrictions on material composition of surfaces in contact with theitem, protection against damage or deterioration, which could occur during movement andplacement, protection against physical damage due to excessive shock or vibration, andprotection against entry of dirt, water, or other contaminants.

3.4 Field Quality Control

3.4.1 Precautions for Austenitic Stainless Steel and Nonferrous Metals

3.4.1.1 All austenitic stainless steel and nonferrous metals shall be protected from blasting,overspray, and coatings not intended for stainless steel surfaces, especially coatingscontaining zinc.

3.4.1.2 Abrasives for use on stainless steel shall be in accordance with SSPC-AB-1 and shallbe free of metals.

3.4.1.3 If hand or power tool cleaning is required on stainless steel or nonferrous metals,stainless steel wire brushes that have not been previously used on carbon steelsurfaces shall be used.

3.4.1.4 Coatings and solvents for use on stainless steel and nonferrous metals shall be freeof substances such as chlorides, sulfur, halogens, or metallic pigments that canharmfully affect stainless steel or nonferrous metals.

3.4.1.5 Color-coding and fabrication markings applied directly on stainless steel andnonferrous metals shall be applied with low-chloride markers.

3.4.2 Precautions for Cathodically Protected Substrates

3.4.2.1 All coatings being used in cathodically protected systems shall be tested andevaluated for cathodic disbondment.

3.4.2.2 Coatings for the cathodically protected systems shall be applied in accordance withthis Practice and the coating system data sheet.
