这是英国标准（BRITISH STANDARD） BS ISO 5658-2-2006+A1-2011 Reaction to fire tests---Spread of flame Part 2: Lateral spread on building and transport products in vertical configuration This part of Iso 5658 is based on the method of the International Maritime Organization(IMO) published.The major differences between Iso 5658-2 and the IMO test are that Iso 5658-2 is limited in scope totesting the spread of flame over vertical specimens and does not include the stack for estimating heat releaseate. The second edition of this part of iso 5658 avoids the use of acetylene for the pilot flame and uses thepropane pilot flame in an impinging mode. The current IMO flame spread procedure is still based onsO5658-2:1996
