The work of preparing international Standards is normally carried out through isO technical committees. Each member body interested in a subject for which a technical committee has been established has the right tobe represented on that committee. International organizations, govern- mental and non-governmental, in liaison with IsO, aiso take part in the work. IsO collaborates closely with the International Electrotechnical Commission(lEC)on all matters of electrotechnical standardization. The main task of technical committees is to prepare International Stan- dards, but in exceptional circumstances a technical committee may types: type 1, when the required support cannot be obtained for the publi- cation of an Internationai Standard, despite repeated efforts; possibility of an agreement on an International Standard: type 3, when a technical committee has collected data of a different kind from that which is normally published as an International Stan- dard ("state of the art", for example). Technicai Reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be transformed into have to be reviewed until the data they provide are considered to be no longer valid or useful.

As early as the 1890s, the hazards of 1ong flowing dancers' dresses and naked-flame 1ights on theatre stages were reported in the United Kingdom. As stated in referenced publications (see Bibliography, items 1. and 2.), the fire behaviour of garments is primarily affected by: a) the fibre content; the construction and mass per unit area of the material(s); b) c) the surface characteristics of the material; and (p the design of the garment. However, it should be noted that the reaction of persons whose clothing is alight can have a significant effect on the burning behaviour of their garments. Results of investigations into the burning behaviour of garments on manikins have been reported (see Bibliography, items 2., 3., 4. and 5.). In all cases the results show that under controlled conditions on a stationary subject, free flowing garments represented a greater ili Copyright International Organization for Standardization Not for Resa
