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 be manufactured in accordance with the requirements of the relevant material standard and
the applicable requirements of this specification. A manufacturing schedule shall be established and applied in
accordance with EN 2078.
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.
Notwithstanding previous acceptance complying with this material standard, any product that is found, at a
later stage, to contain such defects shall be rejected.
Unless otherwise specified, the requirements in Tables 1 and 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. If a specific line number is not shown in
Tables 1 and 2, the requirement is stated in the material standard and/or order.
The requirements of the order and/or material standard shall over-ride the requirements of the technical
specification.
6.2 Qualification requirements
Qualification requirements when invoked by the material standard and/or order are detailed in Tables 1 and 2.
Unless otherwise agreed between the manufacturer and purchaser the qualification phase shall be run on the
first three batches.
6.3 Release requirements
6.3.1 Release tests
Release testing shall be the responsibility of the manufacturer.
The purchaser reserves the right to perform any of the inspections and/or tests required by the material
standard and/or order.
The test samples shall be representative of the product.
When required the manufacturer shall inform the purchaser of the planned dates for extraction of samples and
release testing in order that these operations may be witnessed.
Tables 1 and 2 detail the requirements for each line of the material standard. Unless otherwise specifically
requested by the purchaser, 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.

EN 4800-007:2010 (E)
6.3.2 Retests
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.
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. If all retest results are satisfactory, the batch shall be accepted. If one or more tests are
unsatisfactory, the batch shall be:
rejected; or
100 % retested and the conforming products accepted; or
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. 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 purchaser. 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 purchaser.
6.3.5 Capability clause
Where capability clause is invoked and where sufficient statistical evidence exists, the test need not be carried
out (unless specifically requested by the purchaser).
However, this in no way reduces the obligations of the manufacturer to fulfil the requirements. If subsequent
testing indicates that the product does not comply with the requirements, the batch shall be rejected.
If sufficient statistical evidence does not exist, the test shall be carried out at a frequency agreed between the
manufacturer and the purchaser.
6.3.6 Statistical process control
Reduction in the extent of release testing, other than that defined in 6.3.5 above, may be negotiated with the
purchaser on the basis of appropriate statistical process control and/or statistical data.
6.3.7 Inspection and test report
The manufacturer shall furnish, with each delivery, a report conforming to the requirements of EN 2078 stating
the following:
manufacturer's name and address and, if appropriate, identification of the plant;
order number;
material standard number;
delivery condition and metallurgical code of the product;
8

quantity and dimensions;
manufacturing and inspection schedule reference;
cast and batch number;
batch and/or test samples heat treatment conditions;
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.

2 Chemical composition The test samples used for chemical analysis shall be representative of the product and shall be taken from 2 per cast 2 per cast
each melt or cast. The method of chemical analysis shall be at the discretion of the manufacturer unless
otherwise stated in the material standard or order. In cases of dispute, the method of chemical analysis
shall be agreed between the manufacturer and purchaser preferably using existing chemical analysis
standards. The measured chemical composition shall be stated on the inspection certificate.
Specific requirements for hydrogen content: 1 per cast 1 per cast
The hydrogen content shall be determined on each batch in the delivery condition in accordance with
EN 3976.
3 Method of melting Method of melting shall consist of Cold Hearth (Electron Beam or Plasma Arc) and/or Consumable − −
Electrode Vacuum Arc Melting. An initial non-consumable electrode melt is allowed provided a water-
cooled copper electrode is used. Some of the following requirements depend on whether the melting
method includes Cold Hearth.
1 Raw material:
Raw materials shall be purchased only from suppliers approved by the manufacturer and registered in
his list of approved suppliers.
Approval of suppliers shall be made in accordance with written procedures contained within the quality
assurance system of the manufacturer.
Titanium sponge and alloying elements:
The requirements shall be specified by the manufacturer who shall also establish the following
procedures for the evaluation and acceptance testing of each batch:
— titanium sponge: manufacturing method, level of impurities, particle size, freedom from surface
contamination;
— alloying elements: chemical composition including level of impurities, particle size, freedom from
foreign particles.
