Rubber — Nitrile latex — Determination of residual acrylonitrile content
Refers to latices with a residual acrylonitrile content of less than 0.2 % (m/m). Test portions of latex are distilled, the distillate is collected in methanol. Addition of n-dodecyl mercaptan to the distillate and titration of the excess with a standard iodine solution. - Replaces the first edition (ISO 3899:1976) and constitutes a minor revision.

Fruits and vegetables — Principles and techniques of the controlled atmosphere method of storage
Description of two types of controlled atmospheres: type 1 with slightly reduced oxygen content and more or less enriched in carbon dioxide in such a way that the sum of the contents is 21 % (V/V); type 2 in such a way that the sum of the oxygen and the cabon dioxide contents is below 21 % (V/V). Specification of the method of regulation of atmospheres, of chambers for controlled atmosphere…
