Rubber, raw natural, and rubber latex, natural - Determination of nitrogen content - Fourth Edition
N 1656
Annotation
This International Standard specifies a macro-method and a semi-micro method for the determination of nitrogen in raw natural rubber and in natural rubber latex using variants of the Kjeldahl process.
NOTE The determination of nitrogen in natural rubber is usually carried out in order to arrive at an estimate of the protein content. Minor amounts of non-proteinous nitrogen containing constituents are also present. However, in the dry solids prepared from natural rubber latex, these materials can make a substantial contribution to the total nitrogen content.

Резина, сырой натуральный, и каучуковый латекс, натуральный - Определение содержания азота - Четвертый Выпуск
Этот Международный стандарт определяет макрометод и полумикро метод для определения азота в сыром натуральном каучуке и в натуральном каучуковом латексе с помощью вариантов процесса Kjeldahl.
NOTE определение азота в натуральном каучуке обычно выполняется, чтобы прийти к оценке содержания белка. Незначительные суммы non-proteinous азота, содержащего составляющие, также присутствуют. Однако в сухих твердых частицах, подготовленных от натурального каучукового латекса, эти материалы могут сделать существенный вклад в общее содержание азота.
