Water Vapor Permeability Test Machine - China

Applications:

Water Vapor Permeability Tester is mainly applicable to leathers and textiles used in footwear uppers and clothing where it gives a measure of the ability to remove perspiration from the surface of the wearer's skin.

The tester is used to determine the amount of water vapour a material will transmit through its structure in a specified time.

Standards:

UNI EN IUP/15, UNI EN 13515, EN ISO 20344: 6.6, IUP 15, BS 3144 Method 24, SLP 25, DIN 53333, ISO 17699, DIN 53 429, METODO - 309 WI 009 Product information:

The vapor permeability of leather is evaluated by means of measuring the weight of water-vapor that permeates to specimen per unit time and per unit area.

The main functional components includes: testing holder clamp, ventilation fan, control panel with functions of switch, time setting and recording.

The machine has six separate test stations on a rotary table and each one has a sample holder.

Silica gel desiccant is placed in the holder and the test material is placed over the neck of the holder and secured by a screw top.

After weighing each holder, complete with silica gel and sample material, the holders are placed and locked into the rotary mechanism.

After 7-8 hours the complete holder is weighed again and the gained weight is used to determine the degree of permeability.

It is essential that the entire operation is carried out in a conditioned atmosphere of 20°C and 65% per cent relative humidity.

In addition to the standard equipment, the tester is also supplied with a built-in timer to record the number of hours that testing has been carried out.
