## What the source says

> 7765,IS,,ISO 2781:1988,"Rubber, vulcanized — Determination of density",Caoutchouc vulcanisé — Détermination de la masse volumique,1988-11-24,3,['83.060'],ISO/TC 45/SC 2,9599,[7764],"[41456,43668]","['en','fr']",3,<p>Describes two methods. The determination is important in the control of the quality of a rubber compound and in the calculation of the mass of rubber required to produce a given volume of vulcanizate. Does not cover the relative density of rubber. Gravitational forces under different conditions are observed and expressed in units of mass. - Replaces the second edition (ISO 2781:1981).</p>
