2. Performance Requirements. The oxygen regulator for the Portable Exothermic Cutting Unit (PECU), NSN No. 1H 4240-01-272-3841 is preset at a maximum pressure of 60 pounds per square inch (lb/in²). The exothermic cutting rods for the PECU shall meet the performance requirements listed below while requiring an oxygen flow rate of not greater than 15 specific cubic feet per minute at a pressure of between 20 lb/in² and 60 lb/in².

a. Cutting rate. The exothermic cutting rods shall meet the minimum cutting rate in inches per minute (IPM) or quantity of rods, when cutting through the following materials:

** Quantity of rods not to exceed ten (10) 3/8 inch X 36 inch long.

b. Flame outs. Flame outs shall occur at a rate of not more than one per five rods burned.

c. Burnback. Burnback is defined as when the cutting rod sheath burns faster than the steel fuel on the inside, leaving the steel fuel exposed. Burnback shall occur at a rate of no more than once per five rods burned.

d. Underwater operation. The 3/8 inch diameter cutting rods shall be capable of cutting a 1 inch diameter hole through 1/4 inch thick mild steel plate submerged in water to a depth of 12 inches.

Quality assurance. Sampling for inspection shall be accomplished by the contractor/offeror in accordance with the contract. The government reserves the right to perform any quality inspections or require manufacturer test data, deemed necessary to assure supplies conform to prescribed requirements.
