IESO 4500/Device and Procedure for Collection of Dust Samples in Homes and Public Facilities for Allergen Exposure Assessment
ANSI/Pin Date: December 2008
|
STATUS: On-Hold |
DESCRIPTION:
Exposure to indoor allergens is a major risk factor for the development of asthma. The new Heart, Lung and Blood Institute National Guidelines for the Diagnosis and Management of Asthma (EPR-3, http://www.nhlbi.nih.goc/guidelines/asthma) recommend environmental control of allergy and asthma triggers based on home assessments. Collection of dust samples for analysis by a qualified laboratory is a key component of exposure assessment.

IESO 4700/Method for Field-testing the Momentary Dehumidification Performance of a Portable Dehumidifier
ANSI/Pin Date: December 2008
|
STATUS: On-Hold |
DESCRIPTION:
This standard applies to the field-testing of the dehumidification performance of portable desiccant and cooling-based dehumidifiers during building drying operations. The purpose of testing under this standard is to establish that the equipment is delivering the expected air flow rate and removing the amount of humidity that its manufacturer intended, given the entering air temperature and its humidity ratio during the test. Variables tested under this standard include the dry air flow rate leaving the equipment, as well as the dry bulb temperature and humidity ratio of that air stream as it enters and leaves the equipment. Tolerances of these measurements are limited by the typical operating range of instruments and procedures which are suitable for field use in a rugged environment. Reliable conclusions from testing using this standard include assessment of the momentary humidity removal rate compared to manufacturers’ expectations for operation at the specific inlet air conditions during the test; conditions which will be changing. This standard does not apply to the high-precision instruments and procedures used to test and to rate such equipment at steady-state conditions in a laboratory environment. This standard also excludes the field measurement of the equipment’s electrical consumption and its fuel burn rate, if any. It also excludes measurement of the external static pressure of the dry air stream as it leaves the dehumidifier.

IESO 4400/Thermography to Assist the Restoration of Catastrophic Water Damage
ANSI/Pin Date: December 2008
|
STATUS: On-Hold |
DESCRIPTION:
This standard applies to the use of thermal cameras to help locate and to document areas suspected of having elevated moisture content after a catastrophic water damage event. A catastrophic event is an unexpected, unusual or one-time occurrence, and it is one in which the sources of the water and its initial locations or penetration points are well-understood. This standard does not extend to the use of thermal cameras in forensic building investigations such as determining the causes and pathways of chronic water damage problems or determining the causes and pathways of water leaks through the exterior enclosures of buildings. A chronic water damage problem is one which occurs repeatedly and intermittently over an extended period of time rather than as a one-time, unexpected, catastrophic event.
