1.1 This International Standard specifies a method
for determining the coefficients of starting and sliding
friction of plastic film and sheeting when sliding over
itself or other substances. The method is intended to
be used for non-sticky plastic film and sheeting (in the
following text, referred to simply as film) of up to
approximately 0,5 mm thickness.
1.2 This test method serves primarily for quality
control. It does not give a comprehensive assessment
of the machinability on packaging or processing machines
since other effects, e.g. electrostatic charges,
air cushion, local rise of temperature and abrasion are,
as a rule, involved.
1.3 The static frictional force increases as a rule,
with the time the surfaces are in contact. Therefore,
to get comparable results, this time span is specified.
1.4 Slip properties are sometimes generated by additives
in the plastic material. The additives have
varying degrees of compatibility with the film matrix.
They may bloom or exude to the surface and change
the slip properties. Since these effects are timedependent,
measurements on such films have to be
related to the age of the film.
