Reaction vessel is made up of a bulb tube, ending with a graduated scale tube. Fill the test tube with the hydrochloric acid solution. Through the upper cock you enter the specimen that is a piece of galvanized steel wire of a defined length. When the rapid reaction is completed, the pressure is equalized by the level vessel and you can read by difference the amount of hydrogen developed. A table accompanying the appliance indicates the correspondence between the cubic centimeters of hydrogen developed and the g / m2 of zinc quantity for a given length, taking into account certain temperature and atmospheric pressure values in the laboratory.

Test consists in twisting the straightened wire, 100 times its diameter, around its axis in one direction, subjecting it to a voltage not exceeding 2% of the nominal resistance class, and checking that the number of twists is greater or equal to the value provided by the standard.

Wires of the various classes must exceed the number of alternate bends, as indicated by the standard, depending on their diameter. Standard also sets the bending radius of the supports according to the wire diameter.

Test consists in winding the wire around the test machine vice. A vice remains locked while the other one is driven by an electrical mechanism that causes the wire to break. A software processes the test data and calculates the resistance and elongation of the wire

Test consists in blocking a wire sample from two clamps, one of which remains stationary and the other pulls. This effort is detected by a dial where there is a scale indicating the value in kgF of the effective cable resistance until breaking. (This machine can test up to 10.000 kgF).

Test consists in winding up the rope in a spiral way on the two-wheels grooves, one of which remains stationary and the other one runs thanks to a hydraulic mechanism. This effort is detected by a dial where there is a scale indicating the value in kgF of the effective rope resistance until breaking. (This machine can test up to 10.000 kgF).
