Click on picture to extend it
Purpose :
The Electronic “Lastometer” is intended to assess how much a material can be stretched (distended) simultaneously in two directions without being damaged. This simulates conditions experienced during the lasting operation in footwear manufacture. This method is mainly applicable to footwear upper materials but can be used to assess any sheet material such as leather, plastics and textiles.
Description :
During the test a circular specimen of the material is clamped round its edge and is gradually distended by forcing a small metal ball attached to a plunger through the specimen. At a certain distension, measured is terms of distance travelled by the plunger, either cracks appear in the surface of the material or a lower layer of the material sustains physical damage, this distension is recorded as the first damage point. At a higher distension the material usually burst and this distension can also be recorded.
Supplied with operating instructions and conformity and calibration certificate
Standard : NF EN ISO 17693.
