ities. e. Test and Test Control A test program should be established and implemented to ensure that testing is performed and verified by inspection and audit to demonstrate conformance with design and system readiness requirements. The tests should be performed in accordance with written test procedures; test results should be properly evaluated and acted on. f. Inspection, Test, and Operating Status Measures should be established to provide for the identification of items that have satisfactorily passed required tests and inspections. g. Nonconforming Items Measures should be established to control items that do not conform to specified requirements to prevent inadvertent use or installation. h. Corrective Action Measures should be established to ensure that conditions adverse to fire protection, such as failures, malfunctions, deficiencies, deviations, defective components, uncontrolled combustible material, and nonconformances, are promptly identified, reported, and corrected. i. Records Records should be prepared and maintained to furnish evidence that the criteria enumer- ated above are being met for activities affecting the fire protection program. j. Audits Audits should be conducted and documented to verify compliance with the fire protection program, including design and procurement documents, instructions, procedures, and drawings, and inspection and test activities. 4.
