Rubber or plastics hoses - Determination of volumetric expansion (ISO 6801:1983)

Specifies a test method for hoses under hydrostatic pressure. When used for dispensing specific volumes of fluids, the volumetric capacity of a hose is often required to vary by only small amounts at the dispensing pressure. The standard describes a method of checking that such requirements can be met. A figure shows the arrangement of the apparatus.

Tuyaux en caoutchouc ou en plastique - Détermination de l'expansion volumique (ISO 6801:1983)

La présente Norme internationale spécifie une méthode de détermination de l'expansion volumique des tuyaux en caoutchouc ou en plastique sous pression hydrostatique. La présente Norme internationale ne spécifie pas les dimensions des éprouvettes et les essais en pression puisqu'ils sont spécifiés dans les normes appropriées.

Gumene in polimerne cevi - Ugotavljanje volumskega raztezanja (ISO 6801:1983)

Ta mednarodni standard določa metodo za ugotavljanje volumenskega raztezanja gumenih ali polimernih cevi pod hidrostatičnim tlakom. Ta mednarodni standard ne določa dimenzij preskušancev in preskusnih tlačnikov, ker bodo opisani v ustrezni specifikaciji.

Foreword
I
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of developing International
Standards is carried out through ISO technical committees. Every member body
interested in a subject for which a technical committee has been authorized has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in Iiaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 6801 was developed by Technical Committee ISO/TC 45,
and was circulated to the member bodies in
Rubber and rubber products,
December 1981.

4.1 Prior to testing the hose, the correction factor(s) for the
volumetric capacity of a hose is often required to vary by only
apparatus, to allow for its increased capacity under the test
small amounts at the dispensing pressure. This International
pressure(s), shall be determined as described in 4.2.
Standard describes a method of checking that such re-
quirements tan be met.
4.2 Following the procedure as described in clause 5, using a
length of steel hydraulic tubing with external diameter 6,3 mm
and minimum wall thickness 1,52 mm in place of the test

pieces, determine the correction factor as the mean value of
three expansions.
This International Standard specifies a method for the deter-
mination of the volumetric expansion of rubber or plastics
hoses under hydrostatic pressure. 4.3 If the correction factor, determined at a pressure of
IO,3 MPa, exceeds 0,08 cm3, the apparatus is unsuitable.

the test piece and the test pressurets) as each of which will be
specified in the appropriate specification.
