This International Standard specifies a method for preparing dry, homogeneous films, substantially free of air bubbles, from natural rubber latex concentrate. The procedure is not necessarily suitable for latices from natural sources other than Hevea brasiliensis or for compounded latex, vulcanized latex or artificial dispersions of rubber or synthetic rubber latices.
