and Components
This standard is issued under the fixed designation C1409; 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 (´) indicates an editorial change since the last revision or reapproval.
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.
