MANDATORY APPENDIX I
QUALITY CONTROL SYSTEM
ð25Þ I-1 GENERAL
A Manufacturer, Repair or Relief Valve Recertification
Organization holding or applying for a Certificate of
Authorization shall demonstrate a quality control
program that meets ASME CA-1 and establishes that all
Code requirements, including material, design, fabrication,
examination (by the Manufacturer, Repair, and
Relief Valve Recertification Organization), and for
vessels and vessel parts, inspection (by the Inspector),
will be met. Provided that Code requirements are suitably
identified, the system may include provisions for satisfying
any requirements by the Manufacturer, or User,
which exceed minimum Code requirements and may
include provisions for quality control of non-Code
work. In such systems, the Manufacturer of vessels or
vessel parts may make changes in parts of the system
that do not affect the Code requirements without securing
acceptance by the Inspector.
The system that the Manufacturer uses to meet the requirements
of this Section must be one suitable for the
Manufacturer’s own circumstances. The necessary
scope and detail of the system shall depend on the
complexity of the work15 performed and on the size
and complexity of the Manufacturer’s organization.16 A
written description of the system the Manufacturer
will use to produce a Code item shall be available for
review. Depending upon the circumstances, the description
may be brief or voluminous.
The written description may contain information of a
proprietary nature relating to the Manufacturers or
processes. Therefore, the Code does not require any distribution
of this information except for the Inspector, ASME
Designee, or an ASME-designated organization as covered
by I-16(c) and Section XIII, Mandatory Appendix III, III-
2.13. It is intended that information learned about the
system in connection with the evaluation will be
treated as confidential and that all loaned descriptions
will be returned to the Manufacturer upon completion
of the evaluation.
I-2 OUTLINE OF FEATURES TO BE INCLUDED
IN THE WRITTEN DESCRIPTION OF THE
QUALITY CONTROL SYSTEM
The following is a guide to some of the features that
should be covered in the written description of the
Quality Control System and that is equally applicable
to both shop and field work.
I-3 AUTHORITY AND RESPONSIBILITY
The authority and responsibility of those in charge of
the Quality Control System shall be clearly established.
Persons performing quality control functions shall
have sufficient and well-defined responsibility, the
authority, and the organizational freedom to identify
quality control problems and initiate, recommend, and
provide solutions.
I-4 ORGANIZATION
An organization chart showing the relationships among
management and engineering, purchasing, manufacturing,
construction, inspection, and quality control is
required to reflect the actual organization. The
purpose of this chart is to identify and associate the
various organizational groups with the particular function
for which they are responsible. The Code does not intend
to encroach on the Manufacturer’s right to establish, and
from time to time, to alter, whatever form of organization
the Manufacturer considers appropriate for its Code work.
I-5 DRAWINGS, DESIGN CALCULATIONS, AND
SPECIFICATION CONTROL
The Manufacturer’s or Assembler’s Quality Control
System shall provide procedures that will ensure that
the latest applicable drawings, design calculations, specifications,
and instructions required by the Code, as well as
authorized changes, are used for manufacture, examination,
inspection, and testing.
For Manufacturers or Assemblers of parts who do not
perform or assume any design responsibility for the parts
they manufacture, the Quality Control System need only
describe how design documents, including specifications,
drawings, and sketches, that are received from the
purchaser of the part are controlled, and how the
