The Canada Shipping Act states that a Type A (Parachute Flare) shall be projected to a height of not less than 230m, when fired from approx. a near vertical position.
The burn out shall occur at a height of not less than 45m above sea level and the flare shall descend at a rate of 4.6m/s. The burn duration shall, therefore, be 40s.
The flare shall burn with a luminosity of not less than 25,000 candela.
But, beyond curiousity, you don't really need to know all that.
Just make sure that whatever pyrotechnic distress signals you buy are SOLAS approved.
SOLAS is Safety Of Life At Sea, which is a series of IMO conventions that began as a result of the Titanic disaster. (The Titanic had lifeboats for less than half of all the people on board).
It should say "SOLAS approved" on the pyrotechnic.
Also, flares have an expiry date. They are good for 4 years from date of manufacture. So, make sure when you buy them that they are recently manufactured, thus having lots of "life" left.
HTH and cheers,
