Σύνοψη

This testing apparatus employs a method for testing any boot or shoe upperleather. It is according to BS 3144: 1968 and the method is based on SLP 22 and IUP/10 of the Society of Leather Chemists' Societies. Using this apparatus the following measurements can be made:
1. Duration of flexing which is just sufficient to cause water to penetrate through the sample from one face to the other.
2. The percentage gain of weight of the specimen due to water absorption during one or more specified intervals from the beginning of flexing and
3. The mass of water which is transmitted from one face to the other during one or more specified time intervals.
Once the need has been identified, several techniques are used in order to have the best solution. Design follows and iteration is employed, which is a dynamic procedure used in design, in order to make improvements.
Certainly this results in a design which requires no further refinement or changes so that it can operate with success.
