ASHRAE guideline available for public review

ASHRAE "Measurement Procedures for Gaseous Contaminants in
Commercial Buildings" Draft is online for comment Until September
28, 2015

For the past ten years we have been working on a formal document,

    ASHRAE Guideline G27
    "Measurement Procedures for Gaseous Contaminants in Commercial
    Buildings."

The purpose and scope of the document:

    Purpose: This guideline provides recommended procedures for
    effective measurement of airborne gas and vapor concentrations
    inside commercial buildings.  Its goal is to provide consistent
    procedures to follow so field measurements of contaminant
    concentrations are accurate and reproducible, avoiding typical
    problems that may cause unreliable or inconsistent results,
    while recommending sample acquisition techniques, sampling
    locations in equipment and spaces, sampling requirements, and
    criteria for data analysis.

    Scope: This document provides guidance on the procedures to
    follow when measuring gas-phase concentrations of contaminants
    in commercial buildings.  The subject measurements are those
    used to establish existing, baseline or changed conditions as a
    function of the building systems or interior environments.  The
    methods in this guideline emphasize obtaining meaningful data
    within a reasonable time period at a reasonable cost.

This guideline does not apply to industrial or residential
buildings.  It does not address: (a) specific measurement equipment
or devices, or (b) calibration of instruments."

The public review for Guideline 27P will begin Friday, August, 14,
2015, and end on September 28, 2015.  The draft is online and ready
