Copper Strip Corrosion Test Bomb Conforms to range of standards Precision-machined stainless steel bomb inserts in copper corrosion bath for testing aviation fuels and natural gasoline. Bomb withstands test pressure of 100 psi (689 kPa) per specifications. Threaded cap with O-ring gasket and knurled circumference hand tightens to a positive seal. A 1/8” groove in the bomb threads permit safe, gradual release of pressure when opening the bomb. Device conforms to specifications of ASTM D130, D6074, D6158, IP 154, ISO 2160, DIN 51759, FTM 791-5325 and NF M 07-015. Shipping weight is 2 lbs. Unit tests the corrosiveness of aviation test fuels towards silver. A polished silver strip is immersed in a fuel sample at an elevated temperature. After a specified test period, the strip is removed from the sample, washed and evaluated for corrosion. The fully insulated, thermostatically controlled water bath features a constant water level device. The bath is used in conjunction with the Batch Conversion Kit to immerse six 350 mL test tubes for silver strip corrosion tests. Bath features stainless steel, double-wall construction. Unit conforms to IP 227 specifications.

Open cup models are used for determining sustained burning characteristics of mixtures of flammable and nonflammable liquids or liquids with widely different flash points when assessing flammability characteristics; temperature range is ambient to 100°C (212°F). Closed cup models are used for routine flash point testing in the range of –30 to 300°C (–22 to 572°F). Closed cup testers with an aluminum test cup have a brass lid and shutter; stainless steel test cup testers are furnished with a stainless steel lid and shutter.

Cloud point and pour point are indicators of the lowest temperature of utility for petroleum products. The sample is periodically examined while it is being cooled in the cloud and pour point apparatus. The highest temperature at which haziness is observed (cloud point) or the lowest temperature at which movement of the oil is observed (pour point) is reported as the test result. Bench-model and floor-model test units with multiple four-jacket mechanically refrigerated baths, each factory preset at a different temperature for convenient cloud and pour point testing. Bench model has three baths, set at +30, 0, and –30°F (–1, –18 and –35°C); floor model has four baths, set at +30, 0, –30 and –60°F (–1, –18 –35 and –51°C). Each bath has a phenolic top plate with ports for thermometer and four copper test jackets. Synthetic sponge covers over each top plate and gasketed hoods over each bath prevent excessive ice accumulation around the test jackets. Cascade hermetic refrigeration system provides reliable long term service. Bath interior and cabinet is constructed entirely of stainless steel. Floor model rides on swivel castors. Supplied with test jackets, gaskets, disks, and thermometer holders for test jars and cooling baths.
