This European Standard was approved by CEN on 23 June 2001.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official
versions.

Foreword
This European Standard has been prepared by Technical Committee CEN/TC 125 "Masonry",
the secretariat of which is held by BSI.
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 February 2002, and conflicting national standards
shall be withdrawn at the latest by February 2002.
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, Iceland, Ireland, Italy, Luxembourg,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies a method for determining the level of performance of those
organic coatings classified in prEN 845-1 and prEN 845-2 as type 2 applied as a protective
system to zinc coated steel plate used in the fabrication of ancillary components for masonry.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text, and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of
any of these publications apply to this European Standard only when incorporated in it by
amendment or revision. For undated references the latest edition of the publication referred to
applies (including amendments).
EN 197-1 Cement - Part 1: Composition, specifications and conformity criteria for
common cements.
BS 871:1981 Specification for abrasive paper and cloths.
3 Principle
The performance of organic coatings is determined from tests for impact resistance, abrasion
resistance and an accelerated corrosion test. The impact and abrasion resistance are
determined using a heavy rigid pendulum apparatus whereby the spring loaded tip of the
pendulum strikes the test specimen at a specified distance from bottom dead centre. The
accelerated corrosion performance is determined from the electrical resistance of the organic
coating during a period of exposure to an alkaline solution.
4 Sampling
4.1 Sampling for impact and abrasion tests
The minimum number of specimens for each test shall be six, plus two further specimens, if
required (see 6.2). Test specimens shall be flat plate not less than 300 mm long x 50 mm wide
either:
- cut from a sample of the product, where practicable, or
- purpose made and protected using a process identical to that used to protect the
product.
Where specimens are to be cut from a product, they shall be spaced not less than 300 mm
apart.
NOTE  It is critical to use flat plate since any undulations in the metal will cause local high or low spots.

4.2 Sampling for accelerated corrosion test
The minimum number of specimens shall be three, see 8.1.1. Test specimens shall be flat plate
chosen to suit the test cell dimensions (see Figure 3) but shall preferably be not less than 250
mm long x 100 mm wide either:
- cut from a sample of the product, where practicable, or
- cut from galvanized steel plate to the specification used to produce the product.
Where specimens are to be cut from a product, they shall be spaced not less than 300 mm
apart.
5 Apparatus
5.1 Tolerances
The permissible deviation on masses of the apparatus shall be ± 10 g and on apparatus
dimensions ± 1%.
5.2 Impact and abrasion tests apparatus
5.2.1 Steel pendulum
5.2.2 A typical steel pendulum is shown in Figure 1. Its mass acting at centre of action is 8,71
kg. The pendulum tip for the impact test is 0,5 mm thick and 3 mm wide and made from
hardened carbon steel. The form of the tip used is shown in Figure 2. This is attached to the
pendulum such as to produce a 3 mm wide impact strip (i.e. with the flat dimension
perpendicular to the swing direction of the pendulum).
5.2.3 The pendulum tip used for the abrasion test is of hemi-cylindrical profile, radius
12,5 mm and length 12 mm, and made from hardened carbon steel. The tip is covered with first
quality blue twill emery cloth conforming to the requirements of grade No. 1 of BS 871:1981.
NOTE  At present there is no European Standard or International standard which covers the type and
grade of the emery cloth used with the pendulum apparatus. Accordingly, it has been agreed to refer to
British Standard 871).
