New Test Method for Determination of Charring Depth of Wood Utility Poles Exposed to Simulated Wildland Fires

1. Scope

1.1 The purpose of this test method is to determine burning characteristics and resultant charring depth of wood utility poles exposed to simulated wildland fire conditions. Char development and qualitative structural damage along the pole specimen are reported. 1.2 Units--The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.4 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be used in conducting these tests. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Wildfires has damaged many utility poles, which can cause outages and issues trying to replace poles that have been affected by wildfire. Utility companies have a vested interest in trying to protect the poles during a wildfire.

The title and scope are in draft form and are under development within this ASTM Committee.
