In cooperation with the Office of Law Enforcement Standards (OLES), the National Law Enforcement and Corrections Technology Center (NLECTC) oversees the development of standards and a standards-based testing program in which equipment such as ballistic- and stab-resistant body armor, double-locking metallic handcuffs and semiautomatic pistols are tested on a pass/fail basis. NLECTC also conducts comparative evaluations (testing equipment under field conditions) on patrol vehicles, patrol vehicle tires and replacement brake pads, and cut-, puncture-, and pathogen-resistant gloves. The primary focus of OLES is the development of performance standards and testing methods to ensure that public safety equipment is safe, dependable and effective.
