Tensile testing is used in many industries for research, quality and process control. Tension, compression, peel, shear, tear, puncture and adhesion can all be tested.

SATRA has now introduced a new tensile testing machine (STM 566) rated up to 5,000N. This machine is a robust twin–column model with reliable mechanics incorporating digital software control. It delivers precision performance via high efficiency pre-loaded ballscrews, auto ranging high resolution load cells and digital AC servo drive. The STM 566 machine operates in tension and compression and provides an 800 per cent overload capacity without damaging the load cells.

The supplied software runs on customers’ computer systems, and is user–friendly with large display pages for data input. The program provides a particular strength to the machine operation, allowing pre-loading of a wide range of test methods and giving a range of options for exporting, storage and analysis of results. Ready-to-load software (specific to SATRA test methods) together with test-specific jaws can be provided for a wide range of tests.

The choice of specification and both the quality of components and machine build allows SATRA to offer the STM 566 machine with enhanced capability, reliability and durability. Taking advantage of the latest design techniques and modern components means that we are able to offer this machine at a lower price than our previous model.

Tensile testers represent a core part of the test facilities for many laboratories, either for quality testing or as part of process control.

Tensile Testing Machine attachments

STM 566SB    This specially shaped ‘C’ clamp is normally used in the peel strength testing of footwear sole to upper. It can also be used as a general purpose clamp.Top clamp provided (used in conjunction with 566F or 566QR bottom clamp).

STM 566WT    Supplied as a pair, the top-line bollards are used to determine breaking force and extension at break of whole shoe top-lines.

STM 566NP1    This tests a whole sole unit, complete with protective midsole, for nail penetration.Supplied as jaw set (top and bottom).

STM 566QR    This is a unique self locking jaw with a quick release action, which can be used as a general purpose clamp for many duties.Sold individually (normally a pair would be required).

STM 566NT    Normally called the ‘needle tear test’, this device allows the sample material to be clamped and a series of needles pushed through the material.Bottom clamp provided (used in conjunction with an STM 566F top clamp).

STM 566ST    Often called the ‘Baumann tear test’, this is the industry standard for testing the tear strength of leather.Supplied as a pair of jaws.

STM 566LT    This is used to assess the attachment strength of the shoelace tag to the lace.Top clamp provided (used in conjunction with an STM 566F bottom clamp).

STM 566LH    With this attachment footwear lastometer tests can be carried out to check the burst or crack strength.Supplied as a complete unit.

STM 566HP   This test was developed to assess the strength required to pull a nail from the heel of footwear.Supplied as a pair of jaws.

STM 566HA    This is used to measure the strength of attachment of heel to shoe.Bottom clamp provided (used in conjunction with an STM 566F top clamp).

STM 566TB    These SATRA thread bollards are used to determine the breaking load of threads and laces.Supplied as a pair of jaws.

STM 566H    This attachment is used to determine the strength of footwear insole board, particularly in the seat region.Supplied as a complete unit.

STM 566F    This is a versatile, standard, flat jaw, used for a variety of general purpose clamping.Sold individually (normally a pair would be required).

STM 566NP2    This tests the protective midsole as a separate unit for nail penetration.Supplied as jaw set (top and bottom).

STM 566AF    This is used for testing the strength of adhesion of the finish to the leather or synthetic material. It consists of a hook attached to one jaw and a sample holder to the other.Supplied as jaw set (top and bottom).

STM 566Z    The transverse through thickness tensile strength through thickness of sheet materials, usually called the ‘AZ tensile test’, is measured using this device.Supplied as jaw set (top & bottom).
