D 119 Standard specification for "Low Voltage Rubber Insulating Tape"
3. UNITS
This Standard is based on International System of Units (SI), except where otherwise specified.
4. ELECTRICAL INSULATING PLASTIC TAPE
4.1 Materials and Manufacturer
The tape shall consist of a plastic backing coated on one side with a pressure-sensitive adhesive.
The backing shall be either PVC (Polyvinyl Chloride or copolymer of vinyl chloride and vinyl acetate), or PE (thermoplastic polyethylene) suitably compounded to meet the requirements of this Part of Standard specification. The backing shall be smooth and uniform. The tape edges shall be straight and unbroken.
The pressure sensitive adhesive layer shall be smooth and uniform and as free from lumps and bare spots as the best commercial practice will permit. "Fish Eyes" shall not be cause for rejection. There shall be no adhesive transfer when the tape is unwound from the roll.
The tape shall provide high electrical resistivity, resistance to corrosive environments, low moisture absorption and permeability, and shall form water-tight bond with itself and with rubber tape.
4.2 Requirements
4.2.1 A thermoplastic insulating tape conforming to this Part of Standard specification shall meet the requirements listed in Table 1 and 4.2.2 to 4.2.6 inclusive.
Dec. 1997 IPS-M-TP-750/13
173
4.2.2 Deformation test
4.2.2.1 The thickness of the insulation on a splice covered with PE tape shall not decrease more than 40 percent when conditioned, under pressure, in a full-draft circulating-air oven operating at a temperature of 100.0 ±1.0°C as described in paragraph 4.2.2.2 and the corresponding decrease in thickness shall not be more than 65 percent for PVC tape.
4.2.2.2 A bare 3.3 mm² (No. 12 AWG) solid copper conductor is to be wrapped with successive layers of tape, with each layer of tape directly over the one below, until a thickness of tape equal to approximately 0.8 mm is in place over the conductor. The thickness of the insulation (tape) is to be measured by means of a dead-weight dial micrometer having no added weight and a presser foot 9.5 ±0.2 mm in diameter. The specimen is then to be placed in the oven for 1 h of preliminary heating at a temperature of 100.0 ±1.0°C along with the dial micrometer and a weight to cause the foot of the micrometer to press on a specimen placed between the foot and the anvil with 500 gf or 4.90 N. At the end of 1 h, the specimen is to be placed under the foot of the dial micrometer with the weight added and then is to remain in the oven with the oven operating at full-draft at a temperature of 100.0 ±1.0°C for an additional hour. At the end of the second hour, the dial of the micrometer is to be read, without removing the specimen or the dial micrometer from the oven, and the percent decrease in the thickness of the insulation (tape) is to be calculated.
4.2.3 Storage test
4.2.3.1 A thermoplastic insulating tape shall retain its adhesive qualities so as to be capable of being used to insulate splices when an unused roll of tape is conditioned in a full-draft circulating-air oven operating at a temperature of 40.0 ±1.0°C for 60 days or, at the manufacturer’s option, a temperature of 65.0 ±1.0°C for 240 h (10 days).
4.2.3.2 To determine whether a thermoplastic tape complies with the requirements in paragraph 4.2.3.1, an unused roll of tape, in its original container, is to be laid flat in a full-draft circulating-air oven operating at the temperature and for the time indicated in paragraph 4.2.3.1, after which the tape is to comply with the requirements in Table 13.1 for adhesion strength.
4.2.4 Test for indirect measurement of conductor corrosion
4.2.4.1 PVC tape shall exhibit a resistance of 1.0 teraohm (1,000,000 megohms) or more for a 25 mm width of tape when five specimens are tested in accordance with the ASTM D 1000 82a, using copper electrodes. The conditioning temperature of specimens with the copper electrodes shall be 23.0 ±1.0°C.
4.2.5 Roll size
The roll size shall be as follows:
Roll length : 20 m.
Roll width : 19 mm.

The tape shall be smooth and uniform. The tape edges shall be straight and unbroken.
5.1.2 A separator of parchment paper, glazed sheeting, polyester film, or similar material shall be interposed between adjacent layers of a roll of tape and shall cover the outside of the tape.
5.2 Requirements
5.2.1 A rubber splicing tape conforming to this Part of Standard specification shall meet the requirements listed in Table 2 and 5.2.2 to 5.2.5 inclusive.
5.2.2 Sticking and unraveling tendency
When a roll of tape is originally unwound, the separator shall not show undue tendency to stick or to unravel.
5.2.3 Storage test
5.2.3.1 A rubber splicing tape shall retain its adhesive qualities so as to be capable of being used to insulate splices when an unused roll of tape is conditioned in a full-draft circulating-air oven at a temperature of 40.0 ±1.0°C for 60 days (1440 h).
5.2.3.2 To determine whether a rubber tape complies with the requirements in paragraph 5.2.3.1, an unused roll of tape, in its original container, is to be laid flat in a full-draft circulating-air oven
Dec. 1997 IPS-M-TP-750/13
175
operating at a temperature of 40.0 ±1.0°C for 60 days (1440 h). After this conditioning, the tape is not to become unduly attached to the separator and is to meet the fusion test in the ANSI/ASTM D 119.
