Conveyor belts - Determination of elastic modulus (ISO 9856:1989)

Migrated from Progress Sheet (TC Comment) (2000-07-10): TC 188 decided at its 3rd  meeting on 1992-10-08/09 to submit ISO 9856 to the ++ UAP procedure. ++ Doc. has been given to PTE for UAP on 1994-05-20.

Fördergurte - Bestimmung des Elastizitätsmoduls (ISO 9856:1989)

Diese Internationale Norm spezifiziert ein Verfahren zur Bestimmung des Elastizitätsmoduls eines Fördergurts. Anmerkung: Der Elastizitätsmodul wird als wesentlicher Faktor bei der Errechnung der Übergangsabstände nach ISO 5293 benutzt.

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, govern-
mental 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 approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 9856 was prepared by Technical Committee ISO/TC 41,
Pulleys and belts (including veebelts).
Annex A of this International Standard is for information only.

Determination of elastic modulus
Conveyor belts -
1 Scope 4.2 Extensometer, with a measuring length of at least
100 mm and accurate to at least 0,l mm.
This International Standard specifies a method for determining
the elastic modulus of a conveyor belt.
4.3 Recording device, to record the curve of tensile stress
as a function of elongation.
NOTE - The elastic modulus is notably used in the calculation of tran-
sition distances in accordance with IS0 5293. .
5 Test pieces

5.1 Shape and dimensions
The following standards contain provisions which, through
The test piece cut from the full thickness of the belt in the
reference in this text, constitute provisions of this International

Standard. At the time of publication, the editions indicated
50 mm and its length at least 300 mm plus twice the necessary
were valid. All standards are subject to revision, and parties to
clamping zone length.
agreements based on this International Standard are encouraged
to investigate the possibility of applying the most recent editions
