This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee ASD-
STAN.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

3.1
melt
mass of homogeneous liquid metal from a single charge
3.2
remelt
solid metal resulting from a single melt
3.3
parent cast
cast of remelting stock to be used for the production of castings
3.4

analysis
4 Wording of order
The order shall clearly indicate:
— quantities to be supplied;
— dates of delivery;
— material standard 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
The 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 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. 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.
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 Table 1
and Table 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.
Table 1 and Table 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.
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;
