Cellular plastics and rubbers - Determination of linear dimensions (ISO 1923:1981)

Specification of the characteristics and the choice of the measuring equipment and procedure for determination of the linear dimensions of sheets, blocks or test specimens of ceelular material (flexible and rigid). Depending on the range of the dimensions to be measured different measuring instruments are recommended.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national Standards is carried out through IS0 technical committees. Every member
body interested in a subject for which a technical committee has been set up 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.
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.
International Standard IS0 1923 was developed jointly by Technical Committees
ISO/TC 45, Rubber and rubberproducts, and ISO/TC 61, Plastics, and was circulated
to the member bodies in May 1976.
It has been approved by the member bodies of the following countries :
India Poland
Australia
Austria Iran Portugal
Romania
Belgium Israel
Brazil Italy Spain
Sweden
Canada Japan
Korea, Rep. of Switzerland
Czechoslovakia
Finland Mexico Turkey
Netherlands United Kingdom
France
Germany, F. R. New Zealand USA
Hungary Philippines USSR
No member body expressed disapproval of the document.
This second edition cancels and replaces the first edition (i.e. IS0 1923-19721, as well
as IS0 Recommendation R 17944967, of which it constitutes a technical revision.

dimensions
3.4 Metal rule or metal tape, graduated in millimetres and
1 Scope and field of application
permitting reading to an accuracy of 0,5 mm.
This International Standard specifies the characteristics and the
choice of the measuring equipment and procedure for deter-
mination of the linear dimensions of sheets, blocks or test
specimens of cellular material (flexible and rigid).
4 Procedure
2 Definition
4.1 Choice of measuring equipment
For the purposes of this International Standard the following
The choice of measuring equipment shall be in accordance with
definition applies :
the accuracy corresponding to the dimensions to be measured
(see the table) :
linear dimension : The shortest distance, measured with an
instrument according to clause 3, between two specific points,
a) When an instrument accuracy of 0,05 mm is required, a
between two parallel lines or between two parallel planes,
dial gauge (3.1) or micrometer (3.2) shall be used. The
defined by corners, edges or surfaces of the cellular specimen.
micrometer may be used only for specimens of rigid cellular
material with a shape not permitting the use of a dial gauge.
3 Measuring equipment
An accuracy of 0,05 mm shall not normally be required for
dimensions of more than 10 mm.
3.1 Dial gauge with a measuring surface of about 10 cm?
b) When an instrument accuracy of 0,l mm is required, a
The gauging pressure shall be 100 & 10 Pal) and the reading sliding caliper (3.3) shall be used.
accuracy shall be 0,05 mm.
This accuracy of 0,l mm shall not normally be required for
dimensions of more than 100 mm.
