Pressure Piping Components Type Test Regulation
1 This regulation was formulated according to the "Regulation on Safety Supervision of
Special Equipment" (hereinafter referred to as "Regulation") with a view to specifying the
pressure piping components type test work and ensuring the manufacturing quality of pressure
piping components.
2 The pressure piping components type test specified in this regulation is the technical
document examination, specimen inspection and test as well as safety feature test conducted
in order to verify whether the product safety meets the safety technical requirements.
3 For all the pressure piping components applied in the People's Republic of China and
meeting the application scope of ''Regulation", their type test shall meet those specified in this
regulation, and their safety performances shall meet the relevant safety technique
specifications and the basic requirements specified in corresponding standards. In principle,
the safety performances of the imported pressure piping components shall not be less than the
basic requirements on safety performances of the pressure piping components in China.
This regulation excludes the type test of safety valves.
4 The pressure piping components type test shall be carried out by the Type Test Institutions
that are authorized by the General Administration of Quality Supervision, Inspection and
Quarantine. The Type Test Institution shall carry out the pressure piping components type test
within its authorized scope.
5 After accepting the type test invitation of the pressure piping components manufacturing
organization or its entrusted import commission agent, the pressure piping components type
test institution shall develop the type test scheme according to those specified in the relevant
appendix in this regulation, and also shall inform the specific testing time.
6 The manufacturing organization of pressure piping components ot its entrusted import
commission agent shall provide the following data when applying for the type test to the Type
Test Institution.
(1) Name and address of the manufacturing organization (the import commission agent
still shall provide its name and address);
(2) Name, specification scope, technical parameter as well as the accepted standards of
the products applying for type test;
(3) Written statement on not reporting the same application to any other type test
institutions in the past;
( 4) Other data including the design documents needed in the type test.
7 The pressure piping components type test includes the design examination (including the
design documents and manufacture technological documents) and the specimen (test sample)
inspection and test.
The type test procedures include design review, extracting test specimens (test samples),
inspection and test, management of test specimens, issuing type test report and type test
certificate.
See Appendix A for the elementary items and requirements of type test, and see
Appendixes B~I for the the items, contents, methods and requirements of the type tests on
typical products.
Appendixes B~I in this regulation cover the basic requirements on the type test of of the
typical products of pressure piping components, the Type Test Institution shall formulate
detailed type test scheme aiming at specific product structures.
8 The pressure piping components meeting one of the following conditions shall be carried
out with type test.
(1) The manufacturing organization manufactures the typical pressure piping components
specified in Appendixes B~I of this regulation for the first time or for addtional projects;
(2) The manufacturing of pressure piping components is allowed to adopted type test
method;
(3) Requirement specified in the safety technique specifications.
9 The pressure piping components type test shall cover certain range of products in different
test units. The test units shall be divided according to the process function, manufacture
process, design method, structural style and failure mode of the pressure piping components,
ans please see Appendiexes ~I for the range of products covered by the pressure piping
components type test.
10 The Type Test Institution shall carry out inspection and test on the specimens (test
samples) as required. The inspecters and testers shall be responsible for the correctness of the
inspection and test results, anyone shall not fabricate or distort the inspection and test results.
Except for those inspection and test that must be carried out at the sampling site or need
special professional equipments, the test shall be carried out in the test and inspection sites of
the Type Test Institution.
11 After completing the type test, the Type Test Institution shall summarize the data timely
and issue the type test report and certificate (see Appendix J and Appendix K for specific
formats and contents) to its client. If the products are rejected in the type test, the Type Test
Institution still shall report the type test report to the examination and approval authority that
authorizes the manufacturing of pressure piping components.
The Type Test Institution shall keep the relevant original records of type test and the type
test report for a long term.
The Type Test Institution shall fill in the "Summary Statement of Pressure Piping
Components Type Test" (see Appendix L) of the current year to the General Administration of
Quality Supervision, Inspection and Quarantine at the end of one year annually.
12 The type test shall be carried out again when any one of the following conditions is met.
Appendix A ELementary Items and Requirements of Pressure
Piping Components Type Test
Al Design review
The design review includes the examinations on design documents and manufacture
technological documents. As for the pipes, pipe fittings and potted components for the
pressure pipes specified in the national standards, their design documents may not be
examined.
Al.1 Design document examination
The broad contents and requirements of design document examination are as follows.
(1) Whether the design documents such as design drawings and design calculation
sheet are intact, whether the calculation methods adopted in the design are right, and whether
the design data and their sources are approciate;
(2) Whether the structure design that influences the safety performances of products
meets those specified in the technical regulations and standards;
(3) If necessary, the confirmatory calculation shall be conducted so as to determine
whether the design of sampled products has any defects that may impact the safety
performances.
When the relevant safety technique specifications or standards cover no corresponding
structural shapes or design calculation methods on the products produced by the manufacturing
organization, the manufacturing organization shall provide the operating principle introductions
of its products or explanations of design calculation method in its design calculation sheet that
are submitted for examination.
Al.2 .Manufacture technological document examination
The broad contents of examination include whether the manufacture process of the major
production procedures of products meets those specified in the relevant safety technique
specifications and standards and whether the acceptance requirements of products meet the
specifications.
Al.3 Examination result reduction
After the design review, the Type Test Institution shall timely communicate with the
manufacturing organization. When the design documents and manufactur technological
documents fail to meet the relevant provisions, the Type Test Institution shall propose its
correction opinions in written form to the manufacturing organization and also shall confirm
the correction conditions of manufacturing organization.
A2 Sampling
A2.1 Sampling method
A3.3 Testers
