— dates of delivery;
— material designation;
— material standard number, or EN 4877-002 (when the product procurement specification is
described in EN 4877-002);

5 Health and safety
A product safety data sheet shall be available.
NOTE 1 The product in the delivery condition needs to take into account the health and safety laws of the area
of the country when and where it is to be delivered.
The implementation of certain special processes implies using substances or chemical preparations that
may present risks for health, safety, or the environment.
NOTE 2 In addition to the regulations in effect in the country where the process is performed, the purchaser
can prohibit and/or restrict the use of certain substances by its subcontractors. These prohibitions and/or
restrictions can be described in the applicable procedures of the purchaser.
When several choices of chemicals exist, the chemicals presenting a lower risk for a given set of
processes should be used.
Furthermore, parties involved should always:
— be informed of and comply with the recommendations and the uses identified provided in the
material safety data sheets for the chemical substances used in processes; and
— apply the prevention and protection measures specified in the safety data sheets and/or resulting
from the workstation chemical risk assessment, in accordance with the applicable health and safety
regulations.
6 List of authorized filler metals
Filler metals authorized with associated material standard are listed in EN 4877-002.
7 Technical requirements
7.1 General
The product shall be manufactured in accordance with the requirements of the relevant product’s
procurement specification and the applicable requirements of this specification. A manufacturing
schedule shall be established and applied in accordance with EN 2078.
Products shall satisfy the requirements of the product’s procurement specification and/or order and
shall be free from irregularities and defects prejudicial to the subsequent manufacture or use of these
products.
Notwithstanding previous acceptance complying with this product’s procurement specification, 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 3 and Table 4 shall apply in conjunction with
those of the relevant product’s procurement specification. Table 3 relates to lines 1 to 29 (inclusive) of
the material standard and Table 4 relates to line 30 onwards in which the sub-line format is also used.
Lines 2 to 98 may also be opened in line 100 if the product’s procurement specification details specific
qualification requirements. If a specific line number is not shown in Table 3 and Table 4, the
requirement is stated in the product’s procurement specification and/or order.
7.2 Supply
7.2.1 Agreement
All products covered by the present document shall be produced by supply sources approved by the
purchaser, according to the procedures in force.
7.2.2 Freezing the production operation sheets
Consistent quality shall be ensured at the time of production.
The manufacturing and inspection operation sheet can be modified by the producer provided that the
proposed modifications have no influence on part quality. It shall inform the purchaser’s Quality
Departments and demonstrate that the level of the product has not been affected by this change.
Otherwise, the request for change shall be submitted to the notice of the purchaser’s Quality
Department for a decision.
The purchaser reserves the right to check the relevance of the changes made by the supply source.
7.2.3 Production process
See Table 3, line 4.2 “Method of production”.
7.2.4 Transformation
The transformation shall make it possible to obtain the dimensional, metallurgical, surface roughness
and quality requirements stipulated in the present document and in the procurement specification of
the product.
7.2.5 Heat treatment
See Table 3, line 6.1 “Delivery condition — Heat treatment”.
7.2.6 Surface condition
Unless indicated otherwise in the product’s procurement document or the order, the required surface
condition is chemical pickling, with prior machine finishing in certain cases. In cases of a product
delivered in annealed condition in a controlled atmosphere, the pickling may be removed if the surface
condition following annealing has no negative effect on the welding.
7.2.7 Batching
Unless otherwise specified in the order or with the agreement of the purchaser, the delivered welding
rods and wires shall come from the same batch.
7.2.8 Packaging
See Table 3, line 6.1 “Delivery condition”.
7.2.9 Marking
See Table 3, line 6.1 “Delivery condition”.
7.2.10 Traceability
Each product shall be traceable to the cast production batch and/or heat treatment batch at all stages of
manufacture and delivery.
Traceability shall be established in order to be able to trace, for each product, the concerned heat, the
manufacturing and heat treatment steps, the inspections and the batches delivered.
The supply source shall keep the documents relative to the manufacture and inspections of the product
at the disposal of the purchaser.
7.3 Inspections and tests
7.3.1 General
7.3.1.1 Qualification of test laboratories
Laboratories performing the inspections and tests described in this document and in the procurement
documents specific to the products shall meet the purchaser requirements applicable to said
inspections and tests.
7.3.1.2 Test frequency
The supply source shall perform all the inspections and tests required in the product’s specific
procurement document and in the present document.
When an inspection frequency is set in this document, it may be alleviated in light of experience, at the
discretion of the Quality Department concerned.
When the present document specifies a test frequency of 10 % of the products, this means that, if the
number of products per batch is N, the tests shall be conducted on a minimum amount of products as
determined by the chart of Table 1.
Table 1
Product amount N Minimum amount of products to test
< 5 N
5 ≤ N < 50 5
50 ≤ N < 200 N/10
N > 200 20
7.3.1.3 Sampling of test pieces
The sample is to be taken from the outer end of the spool.
7.3.1.4 Miscellaneous testing
Additional testing, not specified in the present document, may be required in the product’s specific
procurement documentation.

7.3.6 Bend diameter test
This test is only performed for wires with a diameter ≤ 2 mm.
Four coils on the spool are taken as a sample and left to unwind freely on a flat surface. The coils will
unwind on the flat surface and form a circle, which shall have a diameter between:
— wire diameter ≤ 1,2 mm: 200 mm and 900 mm;
— wire diameter > 1,2 mm: 380 mm and 900 mm.
Frequency: One per spool.
7.3.7 Unwinding test
Fluttering movements on the wire shall not exceed an amplitude of 1 mm measured at 15 mm from the
wire guide outlet.
Frequency: One per spool.
7.3.8 Spiral test
This test is only performed for wires with a diameter ≤ 2 mm.
A spiral is measured on the sample that was used for the bend diameter test. The largest spiral formed
by the coil when placed unattached on a horizontal surface shall not exceed 100 mm (shall not create a
plastic deformation during handling).
Frequency: One per batch.
7.3.9 Melting capacity of product
7.3.9.1 General
The supply source is bound to guarantee the welding capability of the delivered product by checking
the results to be obtained according to the clauses below.
Frequency: Under supply source guarantee. This test is required by the purchaser as part of the
approval in case of customer disputes or difficulties encountered during manufacturing.
7.3.9.2 Wires and rods
7.3.9.2.1 Type of test
For this test, a molten metal deposit is created with the product to be delivered, preferably using the
