3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 4259 and the following apply.

ISO and IEC maintain terminology databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https://www.iso.org/obp/
— IEC Electropedia: available at https://www.electropedia.org/
3.1
filler metal for welding
is supplied in the form of:
— wire
wrought product of uniform solid section supplied in coil or on spools;
— rod
wire supplied in straight cut lengths
4 Wording of order
The order shall clearly indicate:
— quantities to be supplied;
— dates of delivery;
— material standard number;
— marking method;
— delivery condition;
— dimensions and tolerances or reference to an appropriate dimensional standard;
— 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 product 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.

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.
---------------------- Page: 8 ----------------------
SIST EN 3879:2023
EN 3879:2023 (E)

Notwithstanding previous acceptance complying with this material standard, any product that is found,

at a later stage, to contain such defects shall be rejected. Instructions for the use of the material

standard are contained in EN 4258.

Unless otherwise specified, the requirements in Table 1 and in 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.
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 3 (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 6.3.5 “Capability clause”.
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 lengths 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. No product or test sample shall be re-heat

treated more than twice.

EN 3879:2023 (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 the 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.
