Mechanical Systems Insulation
ASHRAE Technical Committee 1.8

Scope of TC 1.8

TC 1.8 is concerned with the application and performance of thermal and acoustical insulation systems used on pipes, tanks, equipment and ducts.

Handbook

The ASHRAE Handbook is published in a series of four volumes, one of which is revised each year, ensuring that no volume is older than four years.

The Handbook can be purchased at the ASHRAE Bookstore by clicking on this link.

This TC is responsible for the following chapter in the Fundamentals Volume:

Insulation for Mechanical Systems
This chapter deals with applications of thermal and acoustical insulation for mechanical systems in residential, commercial, and industrial facilities. Applications include pipes, tanks, vessels and equipment, and ducts.

Comment on the Handbook: ASHRAE welcomes your comments on the Handbook or a specific Handbook chapter.  To submit a comment about any aspect or part of the Handbook series, you can use the Handbook Comment Form.

Review a Handbook Chapter: To provide your feedback about a specific Handbook chapter, you can answer the brief survey questions on the Handbook Chapter Review Form.

Programs

Technical committees develop and sponsor technical sessions at the winter and annual conferences. Information about their future technical program is discussed at each TC meeting and at the TC’s Program Subcommittee meeting.

ASHRAE publishes papers and transactions from presentations at its conference events. In addition, ASHRAE records most of the seminar sessions from its conferences on DVD. These DVDs are ideal for use at chapter meetings, in university courses, or company lunch and learns. Products available from the most recent conference may be found here.

Research

Technical Committees are responsible for identifying research topics, proposing research projects, selecting bidders, and monitoring research projects funded by ASHRAE. Information about their specific research program is discussed at each TC meeting and at the TC’s Research Subcommittee meeting.

This committee has the following active research project:

1646-RP:  MEASUREMENTS OF PIPE INSULATION THERMAL CONDUCTIVITY
The overall objective of the proposed research is to measure the actual thermal conductivity of pipe insulation systems at below ambient temperature in both dry non-condensing and wet condensing conditions with moisture ingress into the insulation.

The committee is working on the following RTAR:

RTAR: Testing the Performance of Vapor Retarder Systems Used with Mechanical Insulation in Below-ambient Applications
The TC voted unanimously to approve this draft research proposal, which ASHRAE calls an RTAR.   We will now send it to the ASHRAE Research Acceptance Committee (RAC) requesting its approval and funding.  It would probably include testing of such materials as ASJ, zero-perm laminates, sheet rubber materials, vapor retarder mastics, and others.  We hope to get this accepted by the next meeting.

Standards

ASHRAE writes standards for the purpose of establishing consensus for: 1) methods of test for use in commerce and 2) performance criteria for use as facilitators with which to guide the industry. ASHRAE publishes the following three types of voluntary consensus standards: Method of Measurement or Test (MOT), Standard Design and Standard Practice. ASHRAE does not write rating standards unless a suitable rating standard will not otherwise be available. ASHRAE is accredited by the American National Standards Institute (ANSI) and follows ANSI's requirements for due process and standards development. Standards may be purchased at the ASHRAE Bookstore.

This TC is not cognizant for any standards at this time.
