What is ISO 2719:2016 Determination of flash point — Pensky-Martens closed cup method?
ISO 2719:2016 specifies a test method for the determination of the flash point of petroleum products, liquids with a viscosity of less than 5.5 mm²/s at 40 °C, and other liquids and mixtures that are not considered to be highly viscous, solid, or highly volatile.
The method is known as the Pensky-Martens closed cup method and is commonly used in the petroleum industry. To determine the flash point of fuels, lubricants, and other products. The test involves heating a sample of the material in a closed cup and applying a flame until a flash is observed.
The temperature at which this occurs is the flash point. Therefore, The test method specified in ISO 2719 is considered to be reliable and is widely used for regulatory and quality control purposes.
What Does ISO 2719:2016 Cover?
This standard applies to:
Petroleum products and liquids with a viscosity less than 5.5 mm²/s at 40 °C
Liquids not highly volatile, solid, or highly viscous
Fuels, lubricants, and related chemical products
It defines the Pensky-Martens closed cup method, where the sample is heated in a closed cup, and an ignition source is introduced to detect the flash.
Requirements of this ISO Standard
Apparatus: The test apparatus must be calibrated and conform to the specifications given in the standard.
Sampling: The sample must be representative of the material being tested and must be taken in accordance with the relevant sampling standard.
Test procedure: The test procedure must be followed exactly as described in the standard. So, this includes the temperature range, heating rate, and ignition source.
Ignition source: The ignition source must be a flame that conforms to the specifications given in the standard.
Reproducibility: The method must be reproducible when used by different operators. Using different apparatus, and with different samples.
Calculation: The flash point must be calculated according to the formula given in the standard.
Reporting: The results must be reported in accordance with the standard. Including units of measurement and any relevant test conditions.
The standard provides detailed guidance on how to perform the test and how to interpret the results. It aims to ensure that the results are accurate, and reliable. Also, comparable across different laboratories and testing facilities.
Benefits of this ISO Standard
Improved safety: The flash point is an important parameter for assessing the fire and explosion hazards of a material. So, By using a standardized test method, it is possible to obtain accurate and reliable results that can be used to develop appropriate safety procedures and guidelines.
Increased efficiency: The Pensky-Martens closed cup method is a relatively quick and easy way to determine the flash point of a material. By following the standardized test procedure outlined in ISO 2719, it is possible to obtain results that are both accurate and reproducible.
Improved comparability: Standardization ensures that the results obtained from different laboratories and testing facilities are comparable. Thus, this allows for easier exchange of information and data between different organizations. And can facilitate the development of international trade.

FAQs – ISO 2719:2016 Flash Point Testing
The flash point is the lowest temperature at which a liquid emits vapor that can ignite when exposed to a flame.
It provides a reliable, closed-system test suitable for moderate- and low-volatility liquids.
While not always legally mandatory, it’s widely accepted for regulatory compliance and internal safety procedures.
As part of routine quality control or whenever there are changes in raw materials or formulations.
No, this method is not suitable for highly volatile or highly viscous materials.
