f) product designation, when required;
g) forwarding address;
h) nature and type of packing, if required;
i) definition and frequency of any special tests and their retest procedures, if required.
5 Health and safety
a) The products in the delivery condition shall fulfil the current health and safety laws of the area of
the country when and where it is to be delivered.
b) A product safety data sheet shall be available.
6 Technical requirements
6.1 General
a) The product shall be manufactured in accordance with the requirements of the relevant material
standard and the applicable requirements of this document.
b) A manufacturing schedule shall be established and applied in accordance with EN 2078.
c) The product shall satisfy the requirements of the material standard and/or order and shall be free
from irregularities prejudicial to the subsequent manufacture or use of this product.
d) Notwithstanding previous acceptance complying with this material standard, any product that is
found, at a later stage, to contain such defects shall be rejected.
e) Unless otherwise specified, the requirements in Table 1 and Table 2 shall apply in conjunction with
those of the relevant material standard. Table 1 relates to lines 1 to 29 (inclusive) of the material
standard and Table 2 relates to lines 30 onwards in which the sub-line format is also used. Lines 2
to 98 may also be opened in line 100 if the material standard details specific qualification
requirements.
f) If a specific line number is not shown in Table 1 and Table 2, the requirement is stated in the
material standard and/or order.
g) The requirements of the order and/or material standard shall override the requirements of the
technical specification.
6.2 Qualification requirements
Qualification requirements, when invoked by the material standard and/or order, are detailed in
Table 1 and Table 2.
Unless otherwise agreed between the manufacturer and customer, the qualification phase shall be run
on the first three batches.
6.3 Release requirements
6.3.1 Release tests
a) Release testing shall be the responsibility of the manufacturer.
b) The customer reserves the right to perform any of the inspections and/or tests required by the
material standard and/or order.
c) The test samples shall be representative of the product.
d) When required, the manufacturer shall inform the customer of the planned dates for extraction of
samples and release testing in order that these operations may be witnessed.
e) Table 1 and Table 2 detail the requirements for each line of the material standard.
f) Unless otherwise specifically requested by the customer, a particular inspection and/or test for
release shall be carried out if corresponding acceptance criteria and/or values are stated in the
applicable material standard, but see also in 6.3.5.
6.3.2 Retests
a) If the test procedure or test piece preparation is faulty, testing shall be re-applied at the original
frequency after rectification of the original cause of failure.
b) When failure cannot be attributed to faulty testing, or test piece preparation, further test samples
shall be selected at twice the original frequency from the product, one of which shall be that on
which the original results were obtained unless already withdrawn by the manufacturer after
suitable identification of the cause of failure.
c) If all retest results are satisfactory, the batch shall be accepted.
d) If one or more tests are unsatisfactory, the batch shall be:
1) rejected; or
2) 100 % retested and the conforming products accepted; or
3) partially or fully re-heat treated if heat treatment can rectify the cause of the failure and tested
as a completely new batch except for chemical composition, for which redetermination of
hydrogen content is required; or
4) cut back and 100 % retested.
e) No product or test sample shall be re-heat treated more than twice.
6.3.3 Rejection
Any failure to meet the requirements of the material standard shall be cause for rejection.
6.3.4 Special tests
Special tests may be required by the customer. In such cases, the nature of the test, method, frequency
and technical requirements shall be specified on the order or inspection schedule and shall be mutually
agreed by the manufacturer and customer.
6.3.5 Capability clause
a) Where capability clause is invoked and where sufficient statistical evidence exists, the test shall not
be carried out (unless specifically requested by the customer).
b) However, this in no way reduces the obligations of the manufacturer to fulfil the requirements.
c) If subsequent testing indicates that the product does not comply with the requirements, the batch
shall be rejected.
d) If sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed
between the manufacturer and the customer.
6.3.6 Statistical process control
Reduction in the extent of release testing, other than that specified in 6.3.5 above, may be negotiated
with the customer on the basis of appropriate statistical process control and/or statistical data.
6.3.7 Inspection and test report
With each delivery, a report shall be furnished which conforms to the requirements of EN 2078 and
states the following:
a) manufacturer's name and address and, if appropriate, identification of the plant;
b) order number;
c) material standard number;
d) delivery condition and metallurgical code of the product;
e) quantity and dimensions;
f) manufacturing and inspection schedule reference;
g) cast and batch number;
h) batch and/or test samples heat treatment condition;
i) results of the tests and retests if any.
6.4 Traceability
Each product shall be traceable to the cast, production batch and/or heat treatment batch at all stages
of manufacture, testing and delivery.
