Your basket is empty. Remove the weighing tube, pour the solution into a beaker, wash the weighing tube held over the beaker with distilled water, pour the solution from the beaker into a volumetric?
It is recommended that the microammeter be marked to read directly in percentage ozone. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
After 24 h of immersion, remove the specimen from the bath, shake vigorously for 5 s to remove adherent moisture, weigh again, and record this weight as W1. The jacket is buffed off, with due care not to buff any further than necessary, or overheat the material. Aging Test Procedures Repeat this procedure four times per minute for a minimum of ten cycles and a maximum of?
Acceptance on Basis of Tests on Short Specimens With the exception of the tear tests, the test specimen shall be either a segment or sector cut with a suitable sharp instrument or a shaped specimen cut out with a die and shall have a cross-sectional area not greater than 0. Take the minimum thickness of the insulation as aastm difference between a measurement made over the conductor or any separator plus the thinnest insulation wall, and the FIG.
Adjust the height of the? Specimens for tests on jackets shall be taken from the completed wire or cable and cut parallel to the axis of the wire or cable.
Calculate the area of a stranded conductor from its maximum diameter. Cool in a dessicator to room temperature. Unless otherwise indicated, the intention is that all reagents conform to the speci? Please download Chrome or Firefox or view our browser tips.

Capacitance and Dissipation Factor Tests. The water absorption test values give an indication of how the insulation will perform in a wet environment. This solution is stable for a week if kept in a cool, dark place in a well-stoppered, brown bottle.
Completely submerge the specimen. Wipe off the excess surface moisture with blotting paper and allow the specimen to remain at room temperature for 10 min. Discard the solution after one week and prepare fresh solution.
ASTM D – 13 – Standard Test Methods for Crosslinked Insulations and Jackets for Wire and Cable
Therefore, tests are done on insulated or jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket and not to test the conductor or completed cable.
If the jacket cannot be removed, prepare specimens by buffing. Continue the immersion for a period of h. NOTE 8—These thicknesses are based on unipass construction.
Repeat the process with the other length of covering, except that the insulation is buffed off. This test provides useful data for research and development, engineering design, quality control, and acceptance or rejection under speci?
