Сети рыболовные. Определение удлинения сетных нитей
Название (англ.):
Fishing nets; Determination of elongation of netting yarns
Описание (англ.):
Tests may be carried out in both the dry and wet states but tests in the wet state are considered to be particularly appropriate in indicating the behaviour of the yarn in use. Any of the following types of tensile testing machines may be used: constant rate of elongations machine; constant rate of traverse machine. Preference should be given to constant rate of elongation machines.
