22、 (ISO member bodies). 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 to be represented on that committee. International organizations,
23、governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

29、s of occupancies where the quantity and/or combustibility of contents is low and fires with relatively low rates of heat release are expected. Examples of occupancies where these sprinklers may be installed include offices, restaurant seating areas, educational facilities and other areas having simi
30、lar fire challenges. These sprinklers have a relatively flat spray pattern compared to the sprinklers described in ISO 6182-1. This allows the sprinklers to effectively distribute water over a larger area; thus permitting the sprinklers to be spaced greater distances from each other, as well as from
31、 the walls of the compartment. Obstructions can pose a greater challenge to extended coverage sprinklers because of the flat spray pattern. Extended coverage sprinkler installation guidelines need to account for the flat spray pattern when considering the distances between obstructions and the sprin
32、kler. Product standards, such as this one, can provide a minimum level of safety in the built environment, as well as a level of quality to the products on the market.
