Specialist alloys are 100% tensile tested
A Lloyd Instruments EZ50 50 kN twin column universal materials testing machine has NEXYGEN MT control and data analysis software giving a vast library of international standard tests.
The Lloyd Instruments universal test equipment range covers forces up to 300kN.
The company's powerful NEXYGEN MT control software has a vast test library for international manufacturing standards compliance.
New features include strict multi-level user security and audit trails for complete traceability of data, video capture and playback, and extended instrument interfaces.
Typical adhesives testing includes tension, compression and peel tests (for example 90deg and 180deg peel adhesion), release force tests, loop tack measurements and dynamic shear.
By fitting environment chambers, it is possible to test adhesives under simulated real life conditions.
One UK adhesive manufacturer is using a 5kN Lloyd Instruments1 test machine, with an environment chamber attached, to test the peel strength of latex based adhesives in self seal envelopes and the bond strength of adhesive drum labels for use cold climates.
Other tests include checking the 'crush' resistance of cardboard tubes (used in cling film, kitchen foil and paper towels packaging) to determine adhesives levels for tube construction.
According to a company spokesman, the set-up has already improved production efficiency and generates detailed data for comprehensive reporting.
Other adhesive industry applications include testing the fatigue properties of structural adhesives in tensile shear (BS EN ISO 9665:1995), adhesives for leather and footwear (BS EN 522:1998), adhesives for tiles (BS EN 12003:1998), the unwinding forces of self adhesive tapes (BS EN 12026:1997), peel tests for flexible bonded to rigid samples (BS EN 28510-1 to 2:1993) and 90deg and 180deg peel strength tests on credit card laminates (ISO/IEC 10373 (Identification Cards - Test Methods).
