This standard specifies the most suitable storage conditions for natural raw rubber and synthetic raw rubber bales. For raw rubber in powder, loose fragments or granular form, due to the large exposed surface area, special care should be taken when storing it. In addition, granular raw rubber will also agglomerate under the influence of higher temperature and (or) pressure.
