1. Scope
1.1 The forced entry resistance of fence systems is evaluated relative to three levels of forced entry threat using a limited hand and small power tool inventory. It, also, establishes a system for rating the forced entry resistance of those systems. The tools specified to be used for testing at each threat level are those that are known to have a maximum destructive effect on structures and their subassemblies and are readily available to aggressors categorized as posing that level of threat. 1.1.1 Low Threat Level (L)--Specifically exempted from the inventory of available tools for the low (L) threat level category are power tools (gasoline, electric, or hydraulic) and devices requiring more than one person to transport and operate. 1.1.2 Medium Threat Level (M)--Specifically exempted from the inventory of available tools for the medium (M) threat level category are power tools requiring an outside power source or self contained with the exception of a cordless -in. (1-cm) drill, gasoline or battery driven tools, and devices requiring more than two persons to transport and operate. 1.1.3 Aggressive Threat Level (A)--Specifically exempted from the inventory of available tools for the high (H) threat level category are devices requiring more than two persons to transport and operate.
