ASTM (American Society for Testing and Materials)  www.astm.org

• ASTM Standard C1060-11A (2011), "Standard Practice for Thermographic Inspection of Insulation Installations in Envelope Cavities of Frame Buildings," ASTM International, West Conshohocken, Pa, 2011, DOI: 10.1520/C1060-11A

This standard practice is a guide to proper use of infrared imaging systems for conducting qualitative thermal inspections of building walls, ceilings, roofs, and floors, framed in wood or metal, that may contain insulation in the spaces between framing members.  This procedure allow the detection of cavities where insulation may be inadequate or missing and allows identification of areas with apparently adequate insulation.

• ASTM Standard C1153-10 (2010), "Standard Practice for Location of Wet Insulation in Roofing Systems Using Infrared Imaging,"   ASTM International, West Conshohocken, Pa, 2011, DOI: 10.1520/C1153-10

This standard practice is used to outline the minimum necessary elements and conditions to obtain an accurate determination of the location of wet insulation in roofing systems using infrared imaging.  This practice is not meant to be an instructional document or to provide all the knowledge and background necessary to provide an accurate analysis. 
 

• ASTM Standard E1186-03 (2009), "Standard Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier Systems,"   ASTM International, West Conshohocken, Pa, 2011, DOI: 10.1520/E1186-03R09

This standard practice covers standardized techniques for locating air leakage sites in building envelopes and air barrier systems.

• ASTM Standard E1862-97 (2010), "Standard Test Methods for Measuring and Compensating for Reflected Temperature Using Infrared Imaging Radiometers,"  ASTM International, West Conshohocken, Pa. 2011, DOI: 10.1520/E1862-97R10

These test methods cover procedures for measuring and compensating for reflected temperature when measuring the surface temperature of a specimen with an infrared imaging radiometer.
 

• ASTM Standard E1897-97 (2010), "Standard Test Methods for Masuring and Compensating for Transmittance of Attenuating Medium Using Infrared Imaging Radiometers,"  ASTM International, West Conshohocken, Pa. 2011, DOI: 10.1520/E1897-97R10

These test methods cover procedures for measuring and compensating for transmittance when using an infrared imaging radiometer to measure the temperature of a specimen through an attenuating medium, such as a window, filter or atmosphere.
 

• ASTM E2018-08, "Standard Guide for Property Condition Assessments: Baseline Property Condition Assessment Process,"  ASTM International, West Conshohocken, Pa. 2011 10.1520/E2018-08

This standard guide outlines procedures for conducting a walk-through non-invasive survey to identify the subject property's physical deficiencies, and recommends various systems, components, and equipment that should be observed by the field observer and reported in the property condition report (PCR).
 

Infraspection Institute www.infraspection.com

• Infraspection Institute "Standard for Infrared Inspection of Building Envelopes"
