Supervision Inspection Regulation
Article 1 In order to standardize the supervision-inspection of pressure piping
components, this Regulation is formulated in accordance with the Special
Equipment Safety Supervision Regulations.
Article 2 This Regulation applies to the manufacturing supervision-inspection
of the pressure piping components (hereinafter referred to as the products) that
are subject to the implementation of the Pressure Pipe Component
Manufacturing License Rules (hereinafter referred to as the supervision-
inspection).
Article 3 The product supervision-inspection shall be undertaken by the
special equipment inspection agency (hereinafter referred to as the
supervision-inspection agency) with corresponding qualifications at the local
manufacturer.
Article 4 The supervision-inspection refers to the conformity verification of the
product by the inspection and inspection institution on the basis of the
qualification of the product quality inspection and test (hereinafter referred to as
self-test) in the manufacturing process of the product. The supervision-
inspection cannot replace the self-test of the manufacturer.
Article 5 The supervision-inspection specified in this Regulation is divided
into three methods. one-by-one, batch-by-batch and annual.
The scopes of products for implementing one-by-one and batch-by-batch
inspections are shown in Annex A. The products not listed in Annex A shall be
subject to annual supervision-inspection.
Article 6 For the supervision-inspection items and requirements, please refer
to the "Supervisory Inspection and Inspection Outline for Pressure Piping
Components" (Annex B, hereinafter referred to as the "Supervision-inspection
Outline").
The inspector who undertakes the supervision-inspection (hereinafter referred
to as the supervision-inspection personnel) shall fill in the results of the
supervision-inspection results in the "Pressure Piping Component
Manufacturing Supervision-inspection Items List" (see Annex C, hereinafter
referred to as the "Supervisory and Inspection Project List").
Article 7 The supervision-inspection agency shall, on the basis of the
VI List of certified welders for welding products (listing license items,
expiration date, welder code, etc.), list of product quality inspectors, list of
nondestructive testing products (listing of certificates, grades, expiration
date, qualification number, etc.);
VII Qualified (subcontracted) party list and evaluation report, subcontract and
subcontractor qualification and relevant personnel qualification certificate
(with administrative license requirements);
VIII Relevant records of quality assurance system implementation such as
management review, non-conforming product (item) control, quality
improvement and service;
IX Related product standards, design documents (where applicable),
process documentation, and inspection and test records;
X Welding procedure assessment list;
XI Type test report and type test certificate;
XII Product contract and technical agreement;
XIII Other materials required by the supervision-inspection.
When the information specified in the preceding paragraph changes, the
manufacturer shall promptly notify the supervision-inspection personnel and
replace it with a valid version.
Article 16 The supervision-inspection personnel shall carry out the
supervision-inspection in accordance with the provisions of this Regulation and
the instructions for the supervision-inspection, record the supervision carried
out, and timely provide relevant witness information (design materials,
inspection and test reports, etc.) provided by the manufacturer, sign for
confirmation on the form of the record, card, etc.)
Article 17 If the supervision-inspection personnel has doubts about the
relevant witness information provided by the manufacturer or finds that it does
not meet the relevant safety technical specifications and the corresponding
standard requirements, he has the right to request the manufacturer to carry
out re-inspection or supplementary inspection.
Article 18 When the supervision-inspection personnel fill out the
"Supervision-inspection Project List", they shall record the supervision
inspection process and results. Fill in "conformity", "non-conformity" or "no such
item" in the "Supervisory Inspection Results" column of the "Supervision-
inspection Project List". Fill in the name of the inspection witness or the name
of the supervision record in the “Work Witness” column. In the "Notes" column,
supervision-inspection within 6 months before April 5, 2014. The next supervision-inspection
date shall be scheduled for the first 6 months of April 5, 2015 (not according to the
implementation date of the supervision-inspection), and so on. However, it cannot exceed the
validity period of the special equipment manufacturing license, that is, April 5, 2017 (according
to the special equipment manufacturing license valid for 4 years).
Article 21 For the products that have passed the one-by-one, batch-by-batch
inspections and comply with relevant safety technical specification and
corresponding standards, the supervision-inspection agency shall adopt the
appropriate method according to the technical characteristics of the products
and the actual situation of the production and management of the product of
the manufacturer, mark the inspection mark on the obvious part of the product.
Article 22 For products that are subject to batch-by-batch inspection, if the
inspection items do not comply with the relevant safety technical specifications
and their corresponding standards, the batch shall be inspected one by one
(set, piece).
Article 23 In the implementation of annual supervision, the inspection and
inspection agency shall, in accordance with the annual period specified in
Article 20, conduct at least a batch of products for each product of each
category (scope) for supervision-inspection. If the sampled products can be
covered downwards in accordance with the relevant provisions of the
manufacturing license, the high-grade products of the variety shall be checked.
When the supervision-inspection items of products that cannot be covered by
each other do not comply with the relevant safety technical specifications and
their corresponding standards, the current annual inspection results of the
products (variety, scope) represented by this level shall be concluded as “non-
conformity”.
When the supervision-inspection items of the products that can be covered
downwards do not meet the relevant safety technical specifications and their
corresponding standards, the current annual inspection results of the products
(variety, scope) represented by the level shall be “non-conformity”. And it shall
also conduct a spot check on the next level of the product, and so on.
Article 24 When the product leaves the factory, the manufacturer shall
provide the supervision-inspection certificate if it implements the inspection of
the product quality and the approval of the product in accordance with the
relevant safety technical specifications.
Article 25 The supervision-inspection agency shall keep the "One-by-one,
batch-by-batch supervision-inspection certificate", the "Annual Supervision-
inspection Report", the "Supervisory and Inspection Project List", the “Quality
Insurance System Inspection Project List”, the “Supervisory Inspection Liaison
Form” and the “Supervisory Opinions” as well as other materials deemed
