Review of requirements and technical review as per ISO 3834-2
5.1 General
When a manufacturer manufactures any product, he should review the requirements of contract along with any other requirements as well as technical data provided by the customer and his own in-house data.
Before starting the manufacturing, manufacturer will establish that all necessary required information is complete and available to perform the manufacturing process.
Manufacturer will adequately ensure his capability to complete the manufacturing as well as successful planning of quality related activities.
Requirements are reviewed by the manufacturer to verify that required product manufacturing is within his capability and he has adequate resources to achieve the delivery schedule as well as to ensure that documentation is unambiguous and clear.
It will be the duty of the manufacturer to identify any difference between this contract and any previous reference as well as to inform the customer for recent programs, costs or engineering changes that may affect the final result.
Points as following are generally to be followed before or at the time of review of requirements.
A) Product standards to be used under any supplementary requirements;
B) Statutory and regulatory requirements;
C) any other requirement prescribed by the manufacturer;
D) Capability of the manufacturer to complete the prescribed requirements
Parts of technical review are generally as following:
a) Parent material (s) specification and welded joint properties;
b) Quality and acceptance requirements of welds;
c) Location, accessibility and sequence of welds, including accessibility for inspection and for non-destructive testing;
d) The specification of welding procedures, non- destructive testing procedure and heat treatment procedures;
e) The approach to be used for the qualification of welding procedures;
f) The qualification of personnel;
g) Selection, identification and / or traceability (e.g. for materials, welds);
h) Quality control arrangements, including the involvement of independent inspection body;
i) Inspection and testing;
j) Sub-contracting;
k) Post weld heat treatment;
l) Other welding requirements, e.g. batch testing of consumables, ferrite content of weld metal, ageing, hydrogen content, permanent backing, use of peening, surface finish, weld profiles;
m) Use of special methods (e.g. to achieve full penetration without backing when welded from one side only);
n) Dimensions and details of joint preparation and complete weld;
o) Welds which are to made in the workshop or else where;
p) Environmental conditions relevant to the application of the process (e.g. very low temperature ambient conditions or any necessity to provide protection against adverse weather conditions);
Handling of non conformance.
