4 Wording of order
The order shall clearly indicate:
 quantities to be supplied;
 dates of delivery;
 material standard number;
 part number;
 delivery condition and metallurgical code of products;
 dimensions and tolerances or reference to an appropriate dimensional standard;
 product designation, when required;
 forwarding address;
 nature and type of packing, if required;
 definition and frequency of any special tests and their retest procedures, if required.
5 Health and safety
Products in the delivery condition shall fulfil the health and safety laws of the area of the country when and
where it is to be delivered.
A product safety data sheet shall be available.
6 Technical requirements
6.1 General
The product shall satisfy the requirements of the order, drawing inspection schedule or material standard: see
Table 1, line 5.
The order, drawing or inspection schedule shall specify the tests to be performed upon:
a) pre-forgings for qualification and/or requalification;
b) serial production forgings for process control testing (Procedure X: see 6.5); and
c) batch release when cut-up testing or forgings is required.
Unless otherwise specified on the order, drawing or inspection schedule, acceptance criteria for the tests are
stated in the material standard, the requirements for each line of which are detailed in Tables 2 and 3 of this
technical specification.
Table 2 related to lines 1 to 29 (inclusive) of the material standard and Table 3 relates to lines 30 onwards in
which the sub-line format is also used. If a particular test is needed but not shown in a specific line in Tables 2
and 3, the requirement shall be specified on the order, drawing, inspection schedule or material standard.
6.2 Qualification requirements
See line 100 in Table 3 of this technical specification.
Qualification shall normally comprise assessment of pre-production forgings. See Table 2, No. 4.2.
6.3 Re-qualification requirements
Re-qualification of serial production forgings may be required, at the purchaser’s discretion, in the following
cases:
 modification of the drawing;
 use of forging stock from a different source;
 modifications to the forging stock form and/or manufacturer route;
 modifications to an existing die;
 use of a new (replacement) die;
 modifications to the forging manufacturing route;
 use of a new forging manufacturer;
 when a significant time interval (usually several years) had elapsed between forging campaigns for a
specific part number;
 when required by the purchaser for any other reason.
Re-qualification testing requirements, especially location of test pieces, shall be identical to those used for the
initial qualification of the pre-production forgings unless otherwise specified on the order, drawing or
inspection schedule.
6.4 Release requirements
Release testing shall be the responsibility of the manufacturer. The sampling procedure for release testing
shall be one of the following, as specified on the order, drawing or inspection schedule. Where no procedure
is specified, procedure A shall be used.
 Procedure A: Separate forged test samples shall be produced from the same batch of forging stock as
that used to make the serial production forgings. Procedure A may be used alone unless denoted AX on
the drawing, order or inspection schedule in which case it shall be applied only in conjunction with
procedure X (see 6.5).
 Procedure B: Separate forged heat treatment control test samples shall be prepared which conform to the
same material standard as the production forgings, but may originate from a different batch of forging
stock. Procedure B shall only be used when full heat treatmen
