PRODUCTS & PROCESSES
Specifications ASTM B827 and ASTM B845 Class III MFG testing protocol were used . This included gases with high corrosion potentials including Hydrogen Sulphide ( H2S ), Nitrous Oxide ( NO2 ), and Chlorine ( Cl2 ).
ASTM B845 refers to techniques for mixed flowing gas ( MFG ) tests containing gases that are applied to evaluate devices containing electrical contacts such as slip rings , separable connectors , electromechanical relays or switch contacts . The MFG tests accelerate corrosive degradation processes . Connectors and contacts within closed electronic cabinets may be affected by an environment of different severity than the outside of these cabinets . ASTM B827 outlines procedures for conducting environmental tests involving exposures to controlled quantities of corrosive gas mixtures . Equipment and methods for gas , temperature , and humidity control for tests to be conducted in a reproducible manner are described .
Reproducibility is measured using control coupons whose corrosion films are evaluated by mass gain , coulometry , or by various electron and X-ray beam analysis techniques . Reproducibility can also be measured by in situ corrosion rate monitors using electrical resistance or mass / frequency change methods . Full copies of these tests can be made available on request .
Industrial applications
SuperCORR A has a proven performance record in protecting electrical components , systems , connectors and electronics . The coating will also prevent the ingress of moisture and other contaminants onto the connector surfaces . These initiate corrosions and cause intermittent component failure or a premature degradation of component performance .
The Battelle Laboratories studies provided data and related processing information validating the benefits of using SuperCORR A . to protect the electrical connectors of line replacement units ( LRUs ) used in military aircraft avionic applications .
The results of the laboratory and field-testing activities conducted in these studies confirm that SuperCORR A is an extremely effective coating to protect electronics , electrical components and systems including switches and connectors with no compromise of the integrity of the electrical component / system even in very corrosive environments .
As a result of testing on site at a number of private and public companies with the confirmatory work at Battelle Laboratories SuperCORR A is being used to reduce maintenance and repair costs in a range of different industrial applications - wastewater treatment plants , pulp and paper mills , automotive and heavy equipment industries and in the power production sector oil and gas and renewable energy and in both the aviation and maritime industries .
