5  Essential variables and range of qualification
5.1  General

The qualification of brazers, (see 5.3) and brazing operators, (see 5.4) is based on essential variables

in accordance with Table 1. For each essential variable, a range of qualification is defined and brazing

outside that range of qualification requires a new qualification test.

NOTE There can be other variables that the manufacturer deems to be essential in certain applications,

e.g. constraint on access for the torch, purging gas, etc., which need separate qualification (see Annex D).

The brazer or brazing operator who undertakes the brazing procedure test satisfactorily in accordance

with this document is qualified provided that the relevant testing requirements of this document are

met.

5.2  Brazing process

Each qualification test qualifies only one brazing process (see Clause 1). A change of brazing process

requires a new qualification test.

When applicable, the furnace atmosphere is limited to the same type of atmosphere, e.g. reducing or

inert, carburizing or decarburizing, and hydrogen or disassociated ammonia, as used in the test.

For brazing processes where fuel gases apply, the qualification is limited to the same type of fuel gas

and flame as used in the test.
5.3  Brazer qualification
5.3.1  Product type

Manual brazing of one product type qualifies for other product types in accordance with Table 2.

Table 2 — Range of qualification for product type
Dimensions in millimetres
Product type for test piece Range of qualification
Plate Plate and pipe
Pipe D ≤ 100 Pipe
Pipe D > 100 Pipe and plate
5.3.2  Type of joint
Range of qualification for type of joint is given by Table 3.
Table 3 — Range of qualification for type of joint
Type of joint in test piece Range of qualification
Butt joint Butt joint
Lap joint Lap joint
T-joint T-joint
5.3.3  Parent material group(s)

In order to minimize the number of brazer qualification tests, parent materials are assigned to

M-number groupings (see Annex E).

The parent material used in the brazer qualification test qualifies the brazer for brazing of all other

parent materials within the same M-number grouping (see Table 4).

Parent materials that do not appear in Annex E, require separate qualification and only qualify that

material.

For a test piece material used for brazer qualification, the brazer is qualified to braze all

materials and all combinations of materials given in the same row.

When test piece material from two rows are used for brazer qualification, the brazer is qualified

to braze all material combinations in each row and combinations between those rows.

5.3.4  Filler metals and brazing filler application

The brazing filler metal type, based on its class in accordance with ISO 17672 or other standards that

provide equivalent technical conditions, qualifies other filler metal types within the same class.

One filler metal form (for example from preformed ring to paste) only qualifies for the same form.

A test with a flux classified in accordance with ISO 18496, or other standards that provide equivalent

technical conditions, only qualifies for brazing within that same classification.

The brazing filler metal application qualifies for other filler metal applications in accordance with

Table 5.
Table 5 — Range of qualification for brazing filler application
Test piece brazing filler application Range of qualification
Face fed Face fed, Pre-placed
Pre-placed Pre-placed

NOTE Face fed”, also known as “applied to the mouth of the joint”, can be manually or mechanically

fed while brazing.
5.3.5  Dimensions

The brazer qualification test of brazed joints is based on the material thickness, outside pipe diameter

and overlap length. The ranges of qualification are specified in Table 6.

For dissimilar material thicknesses of test pieces, the range of qualification is based on the thickness of

each plate (or pipe).

It is not intended that material thicknesses or outside pipe diameters should be measured precisely, but

rather the general philosophy behind the values given in Table 6 should be applied.

For test pieces of different outside pipe diameters and parent material thicknesses, the brazer is

qualified to:
— the larger diameter and below (see Table 6);
— twice the larger parent material thickness and below (see Table 6).

If mechanized or automatic brazing is used for the test, the range of qualification is limited to the

brazing process and type of equipment only (see 6.2).
5.4.2  Filler metals and brazing filler application

If mechanized or automatic brazing is used for the test, the range of qualification is limited to the

method of brazing filler application in accordance with Table 5.
6  Examination and testing
6.1  Supervision

The brazing of test pieces shall be witnessed by the examiner or examining body. The testing shall be

verified by the examiner or examining body.

The test pieces shall be marked with the identification of the examiner and the brazer before brazing

starts.

ISO 13585:2021(E)

The examiner or examining body may stop the test if the brazing conditions are not correct or if it

appears that the brazer or brazing operator does not have the skill to fulfil the requirements.

6.2  Brazing conditions

The qualification test of brazers and brazing operators shall follow a pBPS or BPS prepared in

accordance with ISO 17779. The brazing time for the test piece shall correspond to the working time

under usual production conditions.

The brazer or brazing operator shall prepare the parts (e.g. mechanical preparation, cleaning) or accept

the preparation, set up the heating means and conduct the necessary verification to carry out the test in

accordance with the pBPS or BPS.

NOTE It can be of value to otherwise imitate production conditions for the qualification test as far as

possible.
6.3  Test piece

The test piece may be any design of joint which is relevant to the end work. Typically, this is a basic lap

or butt joint in sheet material or a sleeve joint in tube (for examples of applicable joint configurations,

see Annex F).

NOTE It is possible that requirements concerning test piece design are given in the applicable product

standard.
6.4  Assessment of work pieces
When assembling the test piece, the brazer or brazing operator:
— shall assess the work pieces for:
a) joint fit up;
b) joint gap;
c) degree or absence of local deformation; and

— is permitted to refuse the test piece components if the brazer or brazing operator considers that

these are not in accordance with the written pBPS or BPS.
6.5  Extent of testing

Each test piece shall be tested by visual testing and one or more of the following tests:

a) ultrasonic test;
b) radiographic test;
c) peel test;
d) macroscopic examination;
e) bend test.
6.6  Visual testing

All joints shall be visually examined [see Annex A, item j)] in accordance with EN 12799 or technically

equivalent standards. It can be necessary to cut open the brazed assembly to offer an internal

examination. Therefore, the test may be destructive.
