A-A-52207
The test equipment shall have a capacity of not less than 1 kilovolt ampere.
4.2.3 Resistance to moisture absorption. Immerse the insulated handle in water for a period of 30 minutes, then wipe dry with a cloth and immediately test as follows. Place two metal foil electrodes on the insulated portion of the handle so their inner edges are 1 inch apart. A potential of 7,000 RMS volts peak, 60 hertz, AC shall be applied to the electrodes at a rate of 3,000 volts per second. Apply the test voltage for a period of 30 seconds to determine compliance with 2.3.4 (2).
4.2.4 Resistance to impact. Rigidly mount the insulated handle. Swing a hardened steel cutting edge, suspended as a pendulum, to impart a blow to the handle insulation, equivalent to 5 foot pounds of energy. The cutting edge shall strike the insulation at right angles to the longitudinal axis of the handle to determine compliance with 2.3.4 (3). The cutting edge shall consist of a 90 degree wedge, 0.010 inches in width and 1 inch long.
4.2.5 Resistance to acid. Immerse and soak the insulated handle in a 20 percent sulfuric acid solution for a period of 1 hour at
150EF minimum; then remove from the acid solution and wipe dry. The insulation shall be examined to determine compliance with the applicable requirements of 2.3.4 (4).
4.2.6 Resistance to alkali. Immerse and soak the insulated handle in a 40 percent sodium hydroxide solution for a period of
1 hour at 150EF minimum; then remove from the alkali solution and wipe dry. The insulation shall be examined to determine
compliance with the applicable requirements of 2.3.4 (4).
4.2.7 Performance. Make 10 complete cuts with the cutter on a commercially available carbon hard-drawn spring wire, 0.116 inches in diameter. Make each cut at separate points from the innermost to the outermost points of the cutting edges to determine compliance with the performance requirements of 2.4.
