Pressure piping components type test regulation
1 General provisions
1.1 Purposes
In order to standardize the type test of pressure piping components, this “Regulation”
is formulated, in accordance with the "Special Equipment Safety Law of the People's
Republic of China", "Special Equipment Safety Supervision Regulations", as well as
other relevant laws and regulations.
1.2 Type test
Type test of pressure piping components (hereinafter referred to as type test) is carried
out by an approved inspection agency, that is responsible for type test (hereinafter
referred to as type testing agency), based on the quality inspection and test pass of the
pressure piping component manufacturer (hereinafter referred to as the manufacturer),
in accordance with the provisions of this “Regulation”, to verify its safety and reliability,
by checking whether the product complies with the safety technical specification,
through technical data review, safety performance inspection and test.
1.3 Scope of application
This “Regulation” applies to pressure piping components within the scope of the
"Special Equipment Catalog", which is used within the territory of the People's
Republic of China. For specific products, see Appendix A of this “Regulation”.
1.4 Type testing agency and type testing personnel
1.4.1 Type testing agency
(1) The type testing agency shall obtain corresponding qualifications and engage in
type testing within the approved scope;
(2) The type testing agency shall establish a quality management system and maintain
effective implementation;
(3) After receiving the type test application (or contract), the type testing agency shall
formulate a type test plan in a timely manner and notify the manufacturer to
prepare for the type test;
(4) The type testing agency shall provide the manufacturer with the type testing plan
and the qualifications of the type testing personnel;
(7) When new materials, new technologies, new processes used in manufacturing are
inconsistent with safety technical specifications or there are no requirements that
may have a significant impact on safety performance, review whether the
technical review has been passed and the corresponding approval procedures
have been performed.
2.5.3 Processing of review results
When the design documents and manufacturing process documents comply with
relevant safety technical specifications and the provisions of the based product
standards, the technical documents will be reviewed and determined to be in
compliance. When the technical document review fails to meet the requirements, the
type testing agency shall issue a "Contact sheet for review of technical documents of
pressure piping components" (see Appendix L, hereinafter referred to as "Contact
sheet"), to the manufacturer, to put forward written rectification opinions, AND confirm
the rectification actions of the manufacturer.
2.6 Sampling
2.6.1 Sampling method
Sampling methods shall meet the following requirements:
(1) Type test samples are selected by sampling personnel (type test personnel of the
type testing agency) from the finished product warehouse of the manufacturer
OR the products that have passed the exit-factory inspection and are waiting to
be put into the warehouse at the end of the production line, using random
sampling methods;
(2) Sampling personnel shall be familiar with the structure and manufacturing process
of the samples to be taken. There shall be no less than 2 sampling personnel;
they shall be separated from the personnel responsible for inspection and testing
(except for the items that can be inspected outside the sampling site, in
accordance with the provisions in Appendix C to Appendix K of this
“Regulation”);
(3) Sampling personnel shall verify the production equipment and testing equipment
of the main processes on site; confirm the consistency with the equipment list at
the time of application;
(4) When sampling, the sampling personnel shall review the technical documents,
production records, inspection records and reports of the type test samples; sign
and confirm the reviewed materials.
2.6.2 Sample sealing
After sampling, the sample shall be sealed and meet the following requirements:
(1) The sampling personnel shall fill in the "Special equipment type test sampling
form" (see Appendix M, hereinafter referred to as the "Sampling form"). The
sampling form shall be signed and chopped by both the sampling personnel and
the manufacturer;
(2) The sampling personnel shall seal the samples taken; if necessary, seal copies of
design documents, manufacturing process documents, sample inspection data,
etc., together with the samples;
(3) When samples need to be sent, the date and location of sample delivery shall be
indicated on the "Sampling form".
2.7 Inspection and testing of samples
2.7.1 Basic requirements
The inspection and testing of samples shall meet the following requirements:
(1) The type testing agency shall inspect and test the samples, in accordance with the
type testing plan. Unless otherwise provided in Appendixes C to K of this
“Regulation”, or unless special circumstances require the use of other
professional testing equipment, THEN, the inspection and testing shall be
carried out in the premises where the type testing agency conducts type
inspection and testing.
(2) The type testing agency can recognize the chemical composition and mechanical
properties of the raw materials provided by the manufacturer, as well as the
inspection and test results of non-destructive testing. When there is any doubt,
it shall be inspected and tested.
2.7.2 Test equipment and locations
Test equipment and locations shall m...
