Flash Point is the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. The lower the flash point, the easier it is to ignite the material. Nowadays, Flash point is used to say non-volatile or flammable substances whether exit highly volatile or flammable substances, and has been one of the most important parameters for petroleum products transportation, storage, operations, safety management.

AC-S Open cup flash point tester is designed and made as per the National Standard of People’s Republic of China GB/T261-2008;GB/T21615-2008 & GB/T267- 88; GB/T 3536-2008;European standard;ASTM-D92;ASTM-D93, it is an advanced analytical instrument, mainly used to determine the open and closed flash point of petroleum products. With standardmodular design, a hostcan control thenumber ofopenorclosedtest furnace, be flexibleheaterswhilesharingthe same or differentsamplestesting,and be freelyexchangedbetweenthe testfurnaces, Normal control one to three test furnace at the same time.

Q: What is BDV test for distribution transformer?
A: When you say BDV you might mean the dielectric strength of transformer oil. A new transformer oil should have at lest a dielectric strength of 39 KV. from a British standard.Transformer oils used are normally tested using ASTM D877-82 with the KV strength tester using 1" electrodes spaced 0.1" apart and the test voltage increased at 3,000 volts/min until it breaks down. The average Kv obtained after 8 trials is considered the Oil dielectric strength.
Using this test method,dielectric strength at 30 kv and above is considered good. Dielectric strength between 23 to 29Kv is considered usable, but requires filtering. Below 23 kv, the transformer oil should be replaced. Another method ASTM D18747-82 uses the small radius electrodes but spaced only .o4 inches. The test voltage is 500volts/min and increased until breakdown. The dielectric strength is still the average Kv obtained in 8 trials. The dielectric strength of 28-29Kv is considered good. Below 28 kv, the transformer oil is usable but requires filtering. The latter method is considered a better test method.
