ASTM E605
Full Name
ASTM E605 – Standard Test Methods for Thickness and Density of Sprayed Fire-Resistive Material (SFRM) Applied to Structural Members
Scope
ASTM E605 outlines the standard test methods for determining two critical properties of sprayed fire-resistive materials (SFRM) applied to structural members: thickness and density. These properties are crucial for ensuring the fire resistance performance of SFRM, which plays a vital role in building safety.
Key aspects of ASTM E605 include:
- Scope: the standard covers SFRMs applied to structural steel, concrete, or other substrates. It addresses both field and laboratory testing procedures.
- Thickness measurement – the standard details two methods for measuring thickness:
- Method A – pin penetration: this method involves penetrating the SFRM with a pin of defined dimensions and measuring the penetration depth. It is suitable for field applications.
- Method B – thickness gauge: this method utilizes a calibrated gauge to directly measure the SFRM thickness. It offers higher accuracy and is commonly used in laboratory settings.
- Density determination: ASTM E605 outlines a procedure for determining the density of SFRM by extracting a core sample of known volume and weighing it. The standard provides detailed instructions for sample extraction, preparation, and calculation of density.
- Significance – the data obtained from these tests is crucial for:
- Verifying that the applied SFRM meets the required thickness and density specifications.
- Assessing the uniformity and quality of SFRM application.
- Providing essential information for fire resistance calculations and building code compliance.
