Slot Tear Rig

The measurement of leather slot tear strength is important in the leather and textile industries for evaluating the quality, durability, and performance of leather products that involve slots or openings, such as belts, straps, and other leather accessories. Slot tear strength refers to the force required to initiate and propagate a tear in leather material along a predetermined slit or slot. Measuring slot tear strength provides crucial information about the material's ability to resist tearing and maintain its structural integrity and therefore ensures products are built to last and resist premature tearing.

The slot tear test or Baumann Tear Test to IUP 8 measures the force to tear a slotted sample apart at a constant speed of 100 +/- 20mm/min.  The Standard only requires the maximum force to be measured.  However, the average tear force, force Maxima and Minima by identifying and averaging of the 10 maximum and 10 minimum peak forces and work done can also be measured automatically.

Stable Micro Systems probes and attachments are commonly made from four materials: anodised aluminium (AA6082 T6), stainless steel (316 T), Delrin (acetyl copolymer) and Perspex (polycarbonate).

In general use, probes and attachments made from these materials will be suitable for testing food products and inert non-food materials.

The four materials listed above are not universally resistant to all types of chemicals and as such the compatibility of the probe/attachment material with the product (to be tested) must be established to prevent damage to the probes and attachments. If the compatibility of the product with the probe is unknown to the customer then the chemical information about the product (Material Safety Data Sheet or Product Data Sheet) should be submitted to Stable Micro Systems. Stable Micro Systems will then assess the suitability of the probe/attachment material for use with the product and advise accordingly. If this advice is not sought then Stable Micro Systems will not accept liability for probes/attachments damaged by chemical attack from the product being tested.

All probes and attachments may be cleaned in warm (or hand hot) water using a mild detergent. A soft brush may be used but abrasive cleaning aids should be avoided. Stable Micro Systems products should not be microwaved or cleaned in a dishwasher.

Screw threads should be lightly lubricated after drying using a light lubricant, e.g. petroleum jelly, mineral oil. This will aid the fitting and unscrewing of the item. Each component of a probe or attachment should be wrapped separately when stored, to avoid scratching or chipping. This will safeguard against any unnecessary damage to the accessory.
