As part of the Homeland Security Act of 2002, Public Law 107-296, Congress enacted several levels of liability protection for providers of anti-terrorism technologies. The SAFETY Act (the Act) provides incentives for the development and deployment of anti-terrorism technologies by creating a system of risk management and a system of litigation management.

Standard and Non-Standard Tests

Type	Title	Source	Date	Properties
Standard Test	Cone Calorimeter Test	ASTM E-1354-07	2010
	Notes: Cone calorimeter experiments were conducted on a FTT dual cone calorimeter at incident heat flux settings of 30, 40, 50 kW/m2 with an exhaust flow of 24 L/s using the standardized test procedure (ASTM E-1354-07)
Non-Standard Test	Viscosity test		2010
	Notes: Viscosity tests were carried out using a cone heater to heat the polyurea nanocomposites to the point of decomposition. A small amount of each of the samples was exposed to a heat flux of 40 kW/m2. The procedure began with placing the sample under the cone heater with the shutters closed. The backside of the sample was wrapped in foil and placed on a ceramic blanket on top of the load cell. Then the cone shutters were opened, and the time at which the sample began to smoke heavily was measured. This point, which could be identified within ±1 s, was selected as an indication that the material was close to ignition. At this time the shutters were closed, and the sample was immediately removed from the cone to try to preserve the compositional state of the material at that point. This material was decomposed after 26 seconds with an initial color of tan-green. Rheology data was collected for each treated material using a TA Instruments AR 2000 rheometer , with a heating rate of 2 °C/min and oscillation frequency of 1 Hz.
Non-Standard Test	Blast Load Simulator		2009
	Notes: Quarter scale model walls made of scaled down brick units were used to investigate the response of retrofitted CMUs to external blast loadings. rnThe walls were tested at the US Army Engineer Research and Development Center (ERDC) using the blast simulator

Destructive Tests

Hopkinson Bar	DYNAMIC TESTING USING SPLIT-HOPKINSON PRESSURE BAR (SHPB)		2010
	Notes: Limited number of tensile dynamic testing was performed for the PUPOSS using SHPB
Load to Failure	Quasi-Static test		2009	Constitutive Relations : Elastic Modulus Strength : Tensile Strength Strength : Ultimate Tensile Strain
	Notes: The stress-strain relationships were determined by performing standard direct tension tests using a Servo-hydraulic Material Test Systems (MTS) machine on coupons cut from large panels.
