1.1This guide defines the components of an insulated piping system to be measured or counted to determine quantities and pricing for unit price contracts or extra work.
1.2Pricing may be done through unit pricing for each item by pipe size, type of insulation system, insulation thickness, double or multilayer insulation, type of weatherproofing or jacketing, and pressure rating (if necessary) or through component (fitting) factor or multipliers.
1.2.1Component (fitting) factors or multipliers, which are multipliers times the straight length of piping as shown in Table 1, determine relative prices for each component not within the scope of this guide. These factors or multipliers are to be determined by the insulating contractor relative to the given situation and insulation system specification.
1.2.2It is suggested that only one type of pricing be used on a project.
1.2.3The values stated in inch-pound units are to be regarded as the standard.
1.3This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
