Easy Operation
The Setaflash Series 3e closed cup flash point tester can be operated in 4 easy steps. Below you see the operator sequence.
What is flash point?
A test sample is placed in a heated cup equipped with a lid. An ignition source is introduced through an opening in the lid into the vapor space above the heated sample. Observations are made to determine if the vapor ignites (flashes) at the recorded temperature of the sample.
The determination of flash point is outlined in test methods established by standardization organizations such as the Energy Institute in the UK, ASTM in the USA, CEN in Europe, and ISO internationally.
Moreover, atmospheric pressure can influence the result. Low barometric pressure causes flammable vapors to form at a lower temperature, while high atmospheric pressure delays the formation of flammable vapors until a higher temperature is achieved.
Why should you test for flash point?
Flash point testing has been a well-established practice for over a century, helping to evaluate and classify the safety hazards of materials for classification, storage, and transportation. This testing is utilized across various industries, including petrochemical, waste management, and cosmetics.
The primary purpose of measuring flash point is to ensure that appropriate and specific precautions are taken during the manufacturing, storage, transportation, or usage of liquids.
Flammability is categorized into three main classes:
Extremely flammable: Flash point below 0°C
Highly flammable: Flash point below 23°C
Flammable: Flash point below 60°C
Changes in flash point can indicate the presence of hazardous volatile materials or the adulteration of a product. For instance, pure ethylene glycol has a flash point of 111°C, but with just 2% acetaldehyde, the flash point drops to 29°C. Similarly, adding petroleum spirit to engine oil will lower its flash point, indicating possible adulteration.
Accurate and reliable flash point measurements require standardized testing conditions, as over 20 factors can influence the result. These factors include the dimensions of the test cup and lid, the temperature and position of the ignitor, the dipping sequence and frequency, test duration, heating rate, atmospheric pressure, and more.
What is the difference between Close Cup and Open Cup?
Flash point is determined using either an open cup or closed cup flash point tester. Open cup tests are specified in some regulations and are designed to simulate conditions in open environments. In contrast, closed cup tests more accurately reflect situations where space is confined.
Let us explain the difference a bit more in depth. See below.
Closed cup tests are designed to simulate the scenario of a liquid spill in an enclosed environment. If the liquid is at or above its flash point, exposure to an ignition source could lead to a fire or explosion. In these tests, the sample is placed in a sealed (closed) test cup, and an ignition source is introduced to determine the temperature at which the sample ignites, referred to as its flash point.
Open cup tests are designed to simulate the potential ignition of a liquid spill in open conditions, such as a pool of liquid on the floor. These tests are used for fire point, combustibility, and sustained burning evaluations. The fire point is defined as the lowest temperature at which the liquid's vapors ignite and continue to burn after the ignition source is removed. Combustibility and sustained burning tests are typically conducted at a fixed temperature to assess the continuous burning of the sample.
An open cup tester generally yields a higher flash point compared to a closed cup tester because vapors can freely escape into the atmosphere. Closed cup tests are often preferred due to their greater precision.
The term non-equilibrium indicates that the vapor is not in equilibrium with the liquid. Non-equilibrium flash point tests involve heating the liquid at a steady rate while applying the ignition source at regular intervals.
Advantages:
Well-suited to automation
Universally available instrumentation
Standardized for a wide range of products.
Disadvantages:
Valuable components may escape each time the flame is dipped, leading to artificially high flash points or reduced precision
Significant temperature variation between the liquid and vapor in the cup
Requires a large sample size (50 to 80 ml per test).
Equilibrium
Setaflash
Traditional equilibrium flash point tests use any cup in a water bath to ensure that the liquid and vapor of the sample are in temperature equilibrium. This is achieved through a complex procedure and a very slow heating rate.
The Setaflash small-scale method simplifies the process by using a 2 ml or 4 ml sample, achieving rapid equilibrium between the vapor and liquid in a cup, and providing a reliable flash point result in just one or two minutes.
Advantages:
Improved precision compared to non-equilibrium methods
The Setaflash instrument offers low-cost, fast measurement for a flash/no flash result
Widely used by many industries.
Disadvantages:
Traditional testers can involve a laborious process, especially when larger sample sizes are needed
This type of instrumentation is not universally available.
Which Flash Point Testing Method should You be Using?
The suitable method for testing your sample is typically specified in a product specification or regulation, and in some cases, a referee test method may be indicated, which should be the preferred option. If multiple test methods are provided, the choice will depend on factors such as sample size requirements, testing speed, or precision.
When testing specifically for contaminants, some test methods and procedures are more suitable than others. Generally, an equilibrium test method is recommended for samples that might contain traces of volatile contaminants.
You can see the different Testing Methods below.
Seta Flash Small Scale
These methodologies encompass petroleum products and biodiesel liquid fuels, ranging from -30 to 300 °C, utilizing a compact closed cup tester.
These procedures can ascertain whether a product exhibits flash or not at a designated temperature (flash/no flash method A), or determine the flash point of a sample (method B). When coupled with an electronic thermal flash detector, these methodologies are also applicable for flash point assessments of biodiesel like FAME.
Small-scale testers are additionally employed in compliance with shipping and safety regulations such as CLP, aiding in the definition and classification of flammable and combustible materials.
These testers meet the following methods and regulations:
These testing procedures encompass the determination of the flash point of petroleum products within the temperature range of 40 to 360 °C, utilizing either a manual or automated PMCC apparatus. Additionally, they are employed to ascertain the flash point of biodiesel within the temperature range of 60 to 190 °C, utilizing automated PMCC apparatus.
These testers meet the following methods and regulations:
ASTM D93; IP 34; ISO 2719
Tag
These testing methodologies encompass the determination of the flash point using both manual and automated closed testers for liquids with a viscosity lower than 5.5 mm²/s (cSt) at 40 °C, or below 9.5 mm²/s (cSt) at 25 °C, and with a flash point below 93 °C.

Why does Flash Point Autosamplers not Comply with Flash Point Test Methods?
Flash point autosamplers or carousels are not integrated into any flash point methods. Consequently, flash points obtained through an autosampler should not be relied upon for product classification concerning transportation, safety, health regulations, or specification purposes. Incorrect product classification can lead to serious repercussions.
Sample cups utilized in autosamplers fail to comply with flash point test method requisites due to the following reasons:
Samples contained within a carousel cup with a lid do not satisfy the criteria for a sealed container or the minimum sample volume as prescribed by the test method.
Test methods specify that sample volumes within containers that are less than 50% full can impact the accuracy of the test outcome.
Test methods caution that the loss of volatile materials can lead to the acquisition of inaccurately high flash points.
Furthermore, precision and bias have not been established for Autosamplers. Autosamplers have not undergone any flash point Interlaboratory Study Program (ILS). An ILS study enables the generation of precision and repeatability statements for a test method. Thus, any precision mentioned in flash point test methods does not pertain to autosamplers.
