3.1
batch
As defined in EN 4259 with the following addition:
 for heat treatment using a continuous furnace, a continuous run of less than or equal to 8 h may be
considered as the same heat treatment charge. Continuous heat treatment can be an option.
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;
 surface protection, if appropriate;
 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 current health and safety laws of the area of the country
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.
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
7

---------------------- Page: 9 ----------------------

SIST EN 4700-004:2011
EN 4700-004:2010 (E)
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.
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, coming from at least two casts.
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 by the order, 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.
6.3.2 Retests
If any requirement is not met, retests shall be carried out under the following conditions unless otherwise stated
in the material standard or order.
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, on a test sample located near the first one.
For wire with hardness results below the minimum or above the maximum value, the softest or hardest wire, as
appropriate, shall be submitted to a tensile test. If the results comply with the specified tensile requirements, all
wire shall be accepted.
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 and cleanness inspection. The reheat treatment
shall be stated on the release test certificate.
For cleanness inspection, if the material fails the requirement the product may be cut back before retesting.

EN 4700-004:2010 (E)
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 the 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 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;
 method of melting;
 delivery condition and metallurgical code of the product;
 quantity and dimensions;
 manufacturing and inspection schedule reference;
 cast and batch number;
 all heat treatment, including re-heat treatment and, where appropriate, straightening and stress relieving
parameters, applied to the batch;
 test sample heat treatment;
 results of the tests and retests if any.

agreement with the manufacturer, may set a limit to the amount of one or more such elements and may
require the amount of such elements to be stated in the certificate of analysis.
The specified ranges of chemical composition are based on cast analyses. Any subsequent analytical
checks shall take into consideration the heterogeneity normal to the alloy.
Additionally for remelted products, the samples shall be representative for the remelted ingot, taking into
account any macro segregation.

The alloy shall be made by the process required by the material standard, unless otherwise agreed
between the manufacturer and purchaser. If a specification permits alternative processes, the manufacturer
shall decide which of them shall be used unless the purchaser states a particular preference on his order. In
all instances, the process by which the alloy was made shall be indicated on the release note.

furnace. Remelting shall be terminated not less than 20 mm from the electrode/stub interface and, after
completion of the remelting cycle, the electrode/stub interface shall be examined to verify that the stub and
weld are intact.
