Standard Guide for Measuring and Estimating Quantities of Insulated Piping and Components
SIGNIFICANCE AND USE
5.1 This guide establishes procedures to help parties involved in unit price piping insulation contracts reach agreement as to what components will be counted for pricing purposes.
SCOPE
1.1 This 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.
1.2 Pricing 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.
1.2.1 Component (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.
1.2.2 It is suggested that only one type of pricing be used on a project.
1.2.3 The values stated in inch-pound units are to be regarded as the standard.
1.3 This 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.

INTRODUCTION
Acommittee ofASTM International initiated this guide to improve industry-wide understanding of
thecomponentsinaninsulatedpipingsystemthataffecttheinstalledcostofinsulatingthesystem.The
method of measurement standard used as a bias for this guide is the National Commercial and
Industrial Standards.
ASTM International defines a guide as a series of options or instructions that does not recommend
a specific course of action. A guide only suggests a course of action. Its purpose is to offer guidance
based on a consensus of viewpoints, but not to establish a fixed procedure. A guide is intended to
increase the awareness of the user to available techniques in a given subject area and to provide
information from which subsequent evaluation and standardization can be derived.
It is the intention that this guide will help gain wider acceptance and understanding of the concepts
in the MICA standard.

terms of a request for quotation or commercial contract.
However, users of this guide must be aware that selection of
elements to be counted, categories, and method of measuring
pipe, have a direct bearing on the final total price. Knowledge
of this fact is critical to the selection of the most qualified
installer.
