Icon Flammability

The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) defines a flammable gas as that having a flammable range in air at 20 °C (68 °F) and at a standard pressure of 101.3 kPa (1 atmosphere). Similar definitions of a flammable gas are found in DOT, IATA and IMDG regulations as well as in the Aerosol Dispensers Directive (2008/47/EC).

Impact Analytical offers full flammability testing services, including flash point determination, flame extension, ignition distance testing, and enclosed space ignition testing. This testing is required to determine proper labeling of aerosol products as established in the Global Harmonized System of Classification and Labeling of Chemicals (GHS) as the UN level. We have custom built test stands for both Ignition Distance and Enclosed Space Ignition Testing that fully comply with all regulations, and allow for safe testing. We can provide test results and aid in determining labeling requirements.

Impact Analytical has experience with the labeling regulations in the US, Canada, and the EU. We can help determine which labeling requirements apply to your product, what test methods must be followed, and what label must be applied based on the data (Non-flammable, Flammable, Highly Flammable, etc.). We can provide you with accurate and reliable data for testing consumer product samples, that complies with known U.S., Canadian, and European standards.

  • The US regulations are outlined in 16 CFR 1500.45, and describe the testing required to determine flame extension and flashback for self-pressurized containers.
  • The Canadian regulations for similar testing are outlined in “Consumer Chemicals and Containers Regulations, 2001 (SOR/2001-269), Schedule 1, “TEST FOR DETERMINING THE FLASHBACK AND THE LENGTH OF THE FLAME PROJECTION OF A FLAMMABLE PRODUCT ENCLOSED IN A SPRAY CONTAINER”.
  • The European regulations are outlined in UNECE Part III Classification Procedures, Test Methods and Criteria Relating to Class 2, Class 3, Class 4, Division 5.1, Class 8, and Class 9, Section 31. These regulations include testing requirements for enclosed space ignition, ignition distance, and aerosol foam flammability testing.
  • Flash point analysis is performed on the bulk liquid (rather than the final product with propellant) under various ASTM methods (ASTM D93, D3828, etc.).
