Introduction
Flash point is one of the most important physical properties of flammable liquids, used to evaluate their safety and usability. In the oil, gas, petrochemical, and automotive industries, precise determination of this parameter plays a key role in preventing dangerous incidents. Determining the flash point of different materials not only helps assess ignition risks but also plays a crucial role in selecting appropriate storage and transportation equipment for chemicals.
There are various methods for determining flash point, open cup and closed cup flash point. In this article closed cup method, related standards like ASTM D93, and highlights the role of companies such as Artin Azma Mehr and the advanced flash point measuring devices from NXA, particularly the ATV-21 model was introduced.
What is the Flash Point Closed Cup?
The flash point closed cup method involves determining flash point of the chemicals or liquids in a sealed chamber that increases temperature gradually until the ignition of produced vapors when exposed to a small flame or spark. Compared to the flash point open cup method, the flash point closed cup method is more accurate, as vapors are contained within a closed environment, with no heat exchange with the surrounding environment.
In the flash point open cup method, the liquid is exposed to air, and generally the ignition temperature is higher than the closed cup method. This difference is because of exposure of the vapors on air which reduces their concentration. Therefore, the flash point closed cup method is preferable for materials with high and hazardous ignition potential, especially for safe storage or transportation.
Applications of the Flash Point Closed cup
The flash point closed cup method is widely used in various industries as a critical criterion for assessing ignition risks. This method is particularly applicable in industries such as oil and gas, liquid fuel production, petrochemicals, and even in dye manufacturing and chemical solvents.
The flash point closed cup reveals at what temperature flammable vapors are produced and whether the material poses a risk at normal ambient temperatures. For example, fuels with a low flash point produce vapors quickly at normal ambient temperatures, and in the presence of a spark or small flame, they can pose an ignition hazard.
Standard test method Related to Flash Point Closed cup: ASTM D93
There is numerous testing methods developed by different standard organizations for the precise and standardized determination of the closed flash point. One of the most important international standards in this field is ASTM D93, developed by the American Society for Testing and Materials (ASTM).
The ASTM D93 standard introduces three different methods for measuring the closed flash point of various chemicals and fuels:
1. Method A: This method is used for chemicals that generally have higher flash points. Diesel fuels, engine oils, and lubricants are among the materials tested using this method.
2. Method B: This method is for liquids with lower flash points, such as heating oils and certain petroleum products.
3. Method C: This method applies to specific chemicals and volatile solvents that require specialized testing conditions due to their unique chemical properties.
Flash Point Measuring Devices
To perform these tests, specialized equipment is required that can accurately and reliably provide precise results according to international standards. One of the reputable brands in this field is NXA, which manufactures advanced closed flash point measuring devices. One of the company’s advanced models is the NXA ATV-21, specifically designed for closed flash point testing.
