Measuring device AW-200-4DS for determination of
electric Surface Resistivity of liners, labels and document pockets
required for electrostatic Type B, C and D FIBCs

The measuring device comes out of testing experience of LABORDATA IMTI. It has been developed for use in design and quality control of FIBC manufacturing. The equipment takes into account the demands of the new standard IEC ISO 61340-4-4:2018 "Electrostatic classification of flexible intermediate bulk containers (FIBC)" The measuring device consists of a Teraohm-Meter with accessories. The equipment includes the surface resistivity ring electrode SR 880 and an additional weight in order to reach a total weight of 2500 g demanded by IEC 61340-2-3.

Ring electrode with glass plate and stainless steel plate

For determination of surface resistivity, the measuring voltage is applied by a ring electrode to the test specimens. The measurement voltage of 10 V and 100 V is automatically changed by the device. Measurments shall be done on the insulated glass plate placed on top of the stainless steel plate as required by IEC 61340-2-3 section 8.2.4: The material shall be tested on a smooth flat support having a surface resistivity of more than 1.0 * 10¹³ Ohm.

When teesting take care of the relevant test climates prescribes in the standard.

Case and electrodes are made tough and appropriate for use in rough environments. Operating mistakes and short-circuits at the electrodes are harmless.

Software Version AW-S-4S
This software targets only the surface resistivity tests in a sophisticated manner.
This version evaluates precisely whether an inliner, label or document pocket meets the requirements of one of the various liner/label/pocket types, and which FIBC Type B, C or D it can be assigned to.
But it is not suitable for measuring the derivation resistance. 

Requirements:
PC with WINDOWS 10 and a serial port.
