Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies
casting a vote.
International Standard IS0 12137-2 was prepared by Technical
Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
IS0 12137 consists of the following parts, under the general title Paints
and varnishes - Determination of mar resistance:
- Part 1: Method using a curved stylus
- Par? 2: Method using a pointed stylus

Paints and varnishes - Determination of mar resistance -
Part 2:
Method using a pointed stylus
1 Scope
‘,
1 .l This part of IS0 12137 is one of a series of standards dealing with the sampling and testing of paints,
varnishes and related products.
It specifies a method for determining, using a pointed stylus, the mar resistance of a single coating of a paint,
varnish or related product, or the upper layer of a multicoat system. Part 1 of IS0 12137 specifies a method using
a curved stylus. The choice between the two methods will depend on the particular practical problem.
1.2 This test has been found to be useful in comparing the mar resistance of different coatings. It is most useful
in providing relative ratings for a series of coated panels exhibiting significant differences in mar resistance.

3 Definition
For the purposes of this part of IS0 12137, the following definition applies:
3.1 mar resistance: The resistance of the surface of a paint film to marking or the formation of other defects as
a result of the action of a specified stylus pushed across the surface.
Marring covers a very broad range of defects in the surface of the paint film. These defects include small scratches
and other marks in the surface of the paint film caused by finger nails or car wash brushes, for instance.
The defects are defined as follows:
Plastic deformation - the permanent indentation of the surface with or without any surface blemish or cohesive
a)
fracture.
b) Surface blemish - a superficial surface effect caused by a difference in the scattering of light between the line
of test and the adjacent surface.
c) Surface scratch - a continuous cut or gouge through the surface.
- the presence of a visible surface break or rupture.
d) Cohesive fracture
Combinations of the above.
e)
NOTE - In some cases, one of these types of defect will be of particular importance, while in other cases one of the other
types of defect may be of interest.
4 Principle
The product or system under test is applied at uniform thickness to flat panels of uniform surface texture. After
