Water Vapor Permeability Testing Instrument - China

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.

leather water vapor permeability testing instrument is applicable to the fur or leather water vapor permeability test (like the shoes vamp, upper shoes materials, surface and lining ).

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 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.
