Published on

The introduction of new GHS regulations for aerosols has drastically impacted aerosol classification. This slide deck illustrates how flammability testing has changed, and the impact it may have on the flammability classification of your product.

Flammable Aerosol Testing for HCS 2012 (GHS)

  1. 1. dell tech laboratories ltd. 1 FLAMMABLE AEROSOL TESTING FOR HCS 2012 (GHS) JOE MCCARTHY, LAB SERVICES MANAGER/REGULATORY AFFAIRS SPECIALIST
  2. 2. dell tech laboratories ltd. 2 1. THEN vs. NOW - And why a product that was not flammable THEN may very well be flammable NOW. 2. Performing the tests - Catching Fire, what is sustained combustion? 3. Safety considerations - Fire is not the only way to get burned.
  3. 3. dell tech laboratories ltd. 3 HCS 1994 (THEN) vs. HCS 2012 (NOW) HCS 1994 (THEN) means an aerosol that, when tested by the method described in 16 CFR 1500.45, yields a flame projection exceeding 18 inches at full valve opening, or a flashback (a flame extending back to the valve) at any degree of valve opening; HCS 2012 (NOW) Category 1 Contains ≥ 85% flammable components and the chemical heat of combustion is ≥ 30 kJ/g; or a) For spray aerosols, in the ignition distance test, ignition occurs at a distance ≥ 75 cm (29.5 in), or b) For foam aerosols, in the aerosol foam flammability test (i) the flame height is ≥ 20 cm (7.87 in) and the flame duration ≥ 2 s; or (ii) the flame height is ≥ 4 cm (1.57 in) and the flame duration ≥ 7 s Category 2 Contains > 1% flammable components, or the heat of combustion is ≥ 20 kJ/g; and a) For spray aerosols, in the ignition distance test, ignition occurs at a distance ≤ 15 cm (5.9 in), or in the enclosed space ignition test, the (i) time equivalent is ≤ 300 s/m3; or (ii) Deflagration density is ≤ 300 g/m3 b) For foam aerosols, in the aerosol foam flammability test, the flame height is ≥ 4 cm and the flame duration is ≥ 2 s and it does not meet the criteria for Category 1
  4. 4. dell tech laboratories ltd. 4 1. Can be tested using ASTM D240-02, ISO 13943, NFPA 30B 2. Calculated as a weighted sum of the individual components. n ΔHc (product) = ∑ [wi% × ΔHc(i)] i Literature data available from: NFPA 30B, NIST, CRC, Perry’s Chemical Engineers Handbook, etc. Heat of Combustion (ΔHc)
  5. 5. dell tech laboratories ltd. 5 THEN 1500.45 Method for determining extremely flammable and flammable contents of self-pressurized containers. (a) Equipment required. The test equipment consists of a base 8 inches wide, 2 feet long, marked in 6- inch intervals. A rule 2 feet long and marked in inches is supported horizontally on the side of the base and about 6 inches above it. A paraffin candle 1 inch or more in diameter, and of such height that the top third of the flame is at the height of the horizontal rule, is placed at the zero point in the base. (b) Procedure. The test is conducted in a draft-free area that can be ventilated and cleared after each test. Place the self-pressurized container at a distance of 6 inches from the flame source. Spray for periods of 15 seconds to 20 seconds (one observer noting the extension of the flame and the other operating the container) through the top third of the flame and at a right angle to the flame. The height of the flame should be approximately 2 inches. Take three readings for each test, and average. As a precaution do not spray large quantities in a small, confined space. Free space of previously discharged material Flame Projection/Flashback (THEN) vs. Ignition Distance Test (NOW) NOW
  6. 6. dell tech laboratories ltd. 6 16CFR1500.45 (THEN) vs. Ignition Distance Test (NOW) THEN Fixed Ignition point (6”), Is the flame projection > 18”? Is there a flashback? NOW Increasing ignition point in 15 cm (6”) intervals. Is there sustained combustion?
