ASTM C1409-98

Standard Guide for Measuring and Estimating Quantities of Insulated Piping and Components

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, insulating 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.

Standard Guide for
Measuring and Estimating Quantities of Insulated Piping
and Components
This standard is issued under the fixed designation C 1409; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
A committee of ASTM initiated this guide to improve industry-wide understanding of the
components in an insulated piping system that affect the installed cost of insulating the system. The
method of measurement standard used as a bias for this guide is the National Commercial and
Industrial Standards.
The American Society for Testing and Materials 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.
