4.6 Physical tests.

4.6.1 Tubing (heat shock). The specimen (insulated pair) shall be looped back and wound tightly on itself for five close turns. The ends shall be securely taped, and the specimen shall be placed in an air oven maintained at a temperature of 121±1 °C for 24 hours, plus 5, minus 0 minutes. The specimen shall then be removed from the oven and the insulation examined for strains and cracks under a magnification of at least three diameters (focal distance of 8 centimeters) and meet the requirements of 3.4.1.

4.6.2 Thermal stress cracking. The test of 4.6.1 shall be performed except that the specimen shall be placed in an air oven for 14 days at 100±1 °C. The specimen shall then meet the requirements of 3.4.2.

4.6.3 Cold bend. The specimen of insulated pair and a mandrel of 0.125±.003 inch (.3.17± .08 mm) diameter shall be placed in a cold chamber maintained at a temperature of -55±1 °C for a period of 24 hours. At the end of this time, while still in the cold chamber, the specimen shall be wound around the mandrel for five close turns at a rate of approximately one turn per second. During this processing, no object having a temperature higher than -55±1 °C shall come within twelve inches of the point of the specimen being wound. After the test, the specimen shall be examined under a magnification glass with at least three diameters magnification for visible evidence of cracking of the insulation and meet the requirements of 3.4.3.

4.6.3.1 Cold bend after aging. A specimen of insulated pair shall be placed in an oxygen bomb containing an atmosphere of oxygen at 300+10 pounds per square inch at a temperature of 70+1 °C, and held there for a period of 96 hours, plus 2, minus 0 hours. At the end of this period, the specimen shall be tested as specified in 4.6.3, except the temperature shall be -40+1 °C. The specimen shall then meet the requirements of 3.4.3.

4.6.4 Elongation. A specimen of a full cross-section of conductor pair insulation shall be tested in accordance with

ASTM D470 at a speed of not less than two inches per minute and meet the requirements of 3.4.4.

4.6.4.1 Elongation after aging. A specimen of a full cross-section of conductor pair insulation shall be placed in an air oven conforming to the requirements of ASTM D573 and maintained at a temperature of 100±1 °C for a period of seven days. After a cooling period of at least 24 hours at room temperature, the specimen shall be tested as specified in 4.6.4. The specimen shall then meet the requirements of 3.4.4.1.

4.6.5 Cutting. A specimen of insulated pair shall be cut in half and the insulation stripped from one end of each piece. One piece shall be formed in a loop, the ends of which shall be tightly clamped in one of the grips of a tensile tester. The second piece shall be passed through the loop and its ends shall be tightly clamped in the other grip of the tensile tester. The two bared conductors of a pair shall be connected together. These bared ends shall be connected in series with an electrical alarm circuit and a load shall be applied to the looped conductors by separation of the tensile tester grips at a rate of two inches per minute until they cut through the insulation, thus making electrical contact as indicated by the alarm circuit. If metal grips are used, one of them must be insulated from the rest of the machine to avoid false indications. The specimen shall then meet the requirements of 3.4.5.

4.6.6 Breaking load. The breaking load of an insulated pair shall be determined using the apparatus and method described in method 3212 of FED-STD-228 and shall meet the requirements of 3.4.6.

a. The immersion shall be four hours.

b. All the conductors connected together shall be one terminal and the other terminal shall be the water.

4.7.4 Insulation resistance. The insulation resistance of the cable shall meet the requirements of 3.5.5, and shall be determined as specified in method 6031 of FED-STD-228 with the following exceptions:

a. The test voltage shall be not less than 100V dc.

b. The polarity of the test conductor shall be maintained negative with respect to the other conductors and the water.

c. Each conductor shall be connected to one terminal in turn and the other terminal shall be the other three conductors fastened together plus water ground.

d. If the measurement is made at a temperature other than 15.6 °C, the manufacturer shall correct the measured value of insulation resistance to the resistance at 15.6 °C. However, if the insulation resistance is equal to or greater than that required by 3.5.5 when the measurement is made at a temperature greater than 15.6 °C, no correction factor need be employed. The manufacturer shall demonstrate that the correction factor is accurate for his compound.

e. The insulation resistance test may be terminated in less than one minute if the galvanometer or meter has ceased fluctuating and the reading indicates that a steady insulation resistance value has been obtained.

However, readings obtained on 5% of the lengths after one minute electrification shall be recorded to establish a continuous check of quality.

4.7.5 Mutual capacitance. Following the test of 4.7.4 and while the cable is still immersed, measure the mutual capacitance between the conductors of each pair at a frequency of 1,000Hz to determine compliance with the requirements of 3.5.6.

Attachment 0002

SPRBL1-16-Q-0032 Page 11

4.7.6 Attenuation. The attenuation of each pair shall be measured on a fifty (50) foot length of cable and computed to db per mile. The wet readings shall be taken on cable that has been in water at least 96 hours.

Measurements shall be taken at frequencies of 300Hz, 1 kHz and 4 kHz to establish compliance with 3.5.2. If individual readings do not comply, several samples shall be measured and an average taken. The attenuation shall be calculated from direct measurements of the parameters R, L, C, and G and using the standard formula for the attenuation of a two wire transmission line which is as follows:

A = 8.69 LC)2ωRG)2C2ω2)(G2L2ω2(R1/2( −+++ db/mile

Where attenuation is in decibels per mile, 8.69 is a factor to convert nepers to decibels.

R = Resistance in ohms per loop mile of each conductor pair.

L = Inductance in henries per loop mile of each conductor pair.

C = Capacitance in farads per mile.

G = Conductance in mhos per mile.
