Foreword
This document (EN ISO 17652-2:2003) has been prepared by Technical Committee CEN/TC 121 "Welding", the
secretariat of which is held by DS, in collaboration with Technical Committee ISO/TC 44 “Welding and allied
processes”.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by November 2003, and conflicting national standards shall be withdrawn at the latest
by November 2003.
EN ISO 17652 consists of the following parts, under the general title: Welding – Test for shop primers in relation to
welding and allied processes:
- Part 1: General requirements
- Part 2: Welding properties of shop primers
- Part 3: Thermal cutting
- Part 4: Emission of fumes and gases
Annexes A and ZA are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This part of this European Standard describes tests for assessing the influence of shop primers on the weldability.
The following tests are detailed:
a) Rating test
This screening test provides a method of assessing the relative weldability of a shop primer of a specified thickness
by making a standard weld and subsequently evaluating the severity of the resulting porosity. Rating tests are
suitable for declaration by suppliers of the influence of particular shop primers and similar purposes;
b) Weldability test
This test describes a method for evaluating the weldability of welding consumables and shop primer combinations,
using various arc welding processes. A standard size fillet is produced that enables comparison to be made. An
overall assessment of the quality of the resultant weld is made. Weldability tests may be more closely related to
actual conditions during production.
For precaution for protection of health, safety and environment during testing, see EN ISO 17652-1.

normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For

4 Rating test
4.1 Principle
This test provides a method of assessing the relative weldability of shop primers of a specified thickness by making
a standard weld over a range of shop primers and subsequently evaluating the severity of the resulting porosity.
Only one welding procedure is prescribed, using metal active gas welding (process 135 in accordance with
EN ISO 4063).
The joint configuration and close fit-up are designed to give significant levels of porosity for reasons of
differentiation and reproducibility.
The standard does not specify limits for acceptability as these depend on the practical application. It is expec
