ASTM E605 is an important test method to determine the thickness and density of sprayed fire-resistive materials (SFRM), which is essential for their effective performance. These properties determine whether the SFRM complies with the desired fire protection levels or not. The method establishes a standard procedure to measure the key parameters that enable product evaluation and quality control. The findings are used for reliability checks, performance evaluation, and specification purposes.
ASTM E605 Method
The method has two variations, as follows:
| Thickness Measurement | ASTM E605 involves determining the thickness of SFRM using ultrasonic thickness gauges or caliper measurements. The thickness requirements for fire protection are ensured to be uniform throughout. |
| Density Measurement | The density of SFRM is determined by calculating the mass per unit volume of the samples extracted from the material. Important information about the material composition and performance characteristics is provided. |
