Forevvord
IS0 (the International Organization for Standardization) is a worldwide fed-
eration 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
(I EC) 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 II 562 was prepared jointly by Technical Com-
mittees lSO/TC 57, Metrology and properties of surfaces, Subcommittee
SC 1, Geometrical parameters - Instruments and procedures for
measurement of surface roughness and waviness, lSO/TC 3, limits and
fits, and lSO/TC I 0, Technical drawings, product definition and related
documentation, Subcommittee SC 5, Dimensioning and toierancing.

Introduction
This International Standard is a Geometrical Product Specification (GPS)
standard and is to be regarded as a General GPS standard (see
ISO/rR 14638). It influences chain links 2 and 3 of the chains of standards
for roughness profile and waviness profile and chain link 2 of the chain of
standards for primary profile and is envisaged also to cover roundness and
other form characteristics.
For more detailed information of the relation of this standard to other
standards and the GPS matrix model, see annex B.
For digital instruments, the appropriate filter for surface profile information
is a phase correct filter. The chosen weighting function, for the phase
correct filter, is Gaussian with a 50 % transmission at the cut-off
wavelength. This provides a transmission characteristic with a relatively
sharp cut-off.
It is of importance that the transmission for the cut-off wavelength is 50 %
since the short wave and long wave portions of the surface profile are
separated and can be recombined without altering the surface profile.

INTERNATIONAL STANDARD @ IS0
Geometrical Product Specifications (GPS) - Surface
texture: Profile method - Metrological characteristics of phase
correct filters
1 Scope
This International Standard specifies the metrological characteristics of phase correct filters for the measurement
of surface pofiles.
In particular it specifies how to separate the long and short wave content of a surface profile.
2 Definitions
For the purposes of this International Standard, the following definitions apply.
2.1 profile filter: Filter which serapates profiles into longwave and shortwave components.
2.1.1 phase correct profile filter: Profile filter which does not cause phase shifts which lead to asymmetrical
profile distortions.
phase correct filter mean line (mean line): Long wave profile component which is determined for any point
2.2
of the profile by a weighted mean value derived from adjacent points.
2.3 transmission characteristic of a filter: Characteristic which indicates the amount by which the amplitude of
a sinusoidal profile is attenuated as a function of its wavelength.
2.4 weighting function: Function for calculating the mean line which indicates for each point the weight attached
by the profile in the neighbourhood of that point.
The transmission characteristic of the mean line is the Fourier transformation of the weighting function.
NOTE -
2.5 cut-off wavelength of the phase correct filter: Wavelength of a sinusoidal profile of which 50 5% of the
amplitude is transmitted by the profile filter.
NOTE - Profile filters are identified by their cut-off wavelength value.
