This document specifies guidance on the specification of technically specified rubber (TSR). A grading
system is proposed, based on the origin of the natural rubber content and on properties exhibited by
the rubber.
This document is intended for use by parties involved in the procurement of TSR and is intended to
form a basis from which requirements for a particular case may be more closely specified. As such,
it describes a number of criteria that need to be the subject of appropriate agreement between the
interested parties.All current amendments available at time of purchase are included with the purchase of this document.
