AZA LAB Classic Open Cup Flash Point Apparatus AZA1294
The AZA1294 Classic Open Cup Flash Point Apparatus from AZA LAB is a reliable and cost-effective laboratory instrument designed for the determination of flash point temperature of petroleum products and flammable liquids using the Cleveland Open Cup (COC) method, in full compliance with ASTM D92 and ISO 2592 standards.
This apparatus is widely used in petroleum testing laboratories, quality control facilities, educational institutions, and fuel safety assessment centers, where accurate flammability classification is essential.
Description
Purpose of Flash Point Testing
Flash point testing identifies the lowest temperature at which vapors from a liquid ignite momentarily when exposed to an ignition source. This critical parameter is used to:
-
Classify flammable and combustible liquids
-
Determine safe storage and transportation conditions
-
Evaluate fire and explosion hazards
-
Meet regulatory and insurance requirements
The open cup method provides conservative and realistic results by allowing vapors to disperse freely, closely simulating real-world spill and exposure conditions.
ASTM D92 Cleveland Open Cup Method
The AZA1294 employs the Cleveland Open Cup (COC) test method, recommended for petroleum products with higher flash points, such as:
-
Lubricating oils
-
Diesel fuels
-
Heavy oils
-
Biofuels
-
Transformer and insulating oils
The apparatus consists of a polished brass test cup placed on a controlled heating block. The temperature of the sample is increased at a standardized rate while a manually controlled test flame is passed over the sample surface at defined intervals until flash is observed.
Robust & User-Friendly Design
The AZA1294 features a classic, operator-friendly design that emphasizes accuracy, safety, and repeatability:
-
Thermostatically controlled heating unit for smooth temperature ramp
-
Clear visibility zone for easy flame observation
