161 Spring Elongation Tester
This is a testing machine for evaluating the softness of enamel wire using the spring elongation method.
- A specified weight is hung from one end of the test specimen, and a coil (test specimen) is created by winding it around a mandrel fixed in a horizontal axis chuck at a rotation speed of 50 times per minute. - After measuring the length of the created coil (test specimen), one end is re-fixed in a vertical axis chuck, and a specified weight is attached to the other end, placing the coil (test specimen) on a support table in a non-stretched state. - The support table is lowered at a speed of 50 mm per minute, and after the weight has separated from the support table, it is held for one minute. The weight is then removed, and the coil (test specimen) is left for another minute before measuring its length. - The spring elongation value is calculated from the lengths of the coil (test specimen) before and after the test. <Reference Standards> JIS-(C3003), C3216-3, IEC-60851-3 【Regarding Catalog Download】 Please request the catalog from the related links below or by contacting us. *For products without individual catalogs, please request the comprehensive catalog.
