IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of developing International
IS0 technical committees. Every member body

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 4597/1 was developed by Technical Committee
ISO/TC 61, Pyasfics, and was circulated to the member bodies in February 1978.

This part of IS0 4597 specifies a method of designation for
epoxide resin hardeners and accelerators.
In view of the inevitable variations in production, independently
measured values on a resin designated as being in a particular class for
a given property may possibly fall either,
The object of this designation method is to allocate to each

in the next higher class if the average value is near the upper
limit.
Thus all products having similar properties and therefore likely
to have the same uses will have the same designation, so aiding
users in their choice if producers list the designation in their 4 Designation of a hardener or accelerator
