• for heat treatment using a continuous furnace, a continuous run of less than or equal to eight h may be considered as the same heat treatment charge.
4 Wording of order
The order shall clearly indicate:
a) quantities to be supplied;
b) dates of delivery;
c) material standard number;
d) delivery condition and metallurgical code of products;
e) dimensions and tolerances or reference to an appropriate dimensional standard;
fj product designation, when required;
g) forwarding address;
h) nature and type of packing, if required;
1) surface protection, if appropriate;
j) definition and frequency of any special tests and their retest procedures, if required.
5 Health and safety
The product 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.
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 satist 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 imperfection 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 I 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. The number of batches and casts shall be agreed between the manufacturer and the customer.
6.3 Release requirements
6.3.1 Release tests
Release testing shall be the responsibility ot the manutacturer.
The customer 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 customer 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 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.
If any requirement is not met, retests shall be carried out following an agreement between manufacturer and customer. Products shall be:
a) rejected; or
h) 100 % retested and the conforming products accepted; or
c) partially or fully re-heat treated if heat treatment can rectif’ the cause of the failure and retested. For condition of use material the number if re-heat treatments shall not exceed the number specified in Table I (line 7). The reheat treatment shall be stated on the release test certificate.
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 the customer.
6.3.5 Capability clause
Where the capability clause is invoked and where sufficient statistical evidence exists, the test need not
he carried out (unless specifically requested by the customer).
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 customer.
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 customer 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:
a) manufacturer’s name and address and, if appropriate, identification of the plant;
b] order number;
c) material standard number;
d) method of melting;
e) delivery condition and metallurgical code of the product;
f) quantity and dimensions;
g) manufacturing and inspection schedule reference if required by the customer;
h) cast and batch number;
i) all heat treatment, including re-heat treatment and, where appropriate, straightening and stress
relieving parameters, applied to the batch;
i) test samples heat treatment;
k) results of the tests and any retests if required by the customer.
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.
