ISO 705:2015规定了在5°C和40°C之间测定天然胶乳浓缩物密度的方法。 ISO 705:2015适用于在无法直接称重或控制实验室温度的位置，使用密度测定来计算测得体积乳胶的质量。

ISO 705:2015 specifies a method for the determination of the density of natural rubber latex concentrate between the temperatures of 5 °C and 40 °C. ISO 705:2015 is intended for use when density determinations are used to calculate the mass of a measured volume of latex in locations where it is not practical to weigh directly or to control the temperature of the laboratory.
