1. SCOPE

1.1 Scope. The purpose of this specification is to provide methods of directly marking wire/cable, or indirectly marking using marker sleeves and heat shrinkable sleeving, and the specific requirements needed for performance of marking. Variations of wire and cable are as follows : insulated single conductor wire, shielded–jacketed single and multi–conductor cable, jacketed multi–conductor cable, shielded cable, unjack-eted cable, twinax cable, triax cable, coax cable, and fiber optic cable. The preferred methods of marking to be used at Sikorsky aircraft in order of precedence are: Laser, Ink jet, Sleeve markers, Sleeving (wrap around and heat shrinkable). SS8798 calls out this specification for marking of wire and cable.

NOTE: Hot impression stamping of wire/cable is not a recommended method for marking wire and cable. It shall only be used as an exception with the approval of Sikorsky Aircraft and shall meet all the requirements of SS7334.

3.0 REQUIREMENTS

Note: CO2 type laser (YAG) marking Shall Only be used in accordance with para 3.2.1.1 for any wire/cable marked at or for Sikorsky aircraft.

3.1 PERSONNEL – Only experienced personnel (personnel who have satisfactorily demonstrated a level of proficiency determined by manufacturing shop supervision), or personnel under the guid-ance of an experienced operator may accomplish identification of electrical wiring.

3.2 MATERIALS AND EQUIPMENT. Are listed in order of precedence for wire and cable marked at Sikorsky Aircraft. Sikorsky Aircraft and Suppliers shall follow the order of precedence unless specific marking is required by contract or purchase order. Sikorsky Aircraft and suppliers shall meet the individual requirements for each marking that is applicable, in accordance with this specifi-cation. Variations for the equipment as stated in this specification are acceptable for use by suppli-ers as long as all other requirements in this specification are met. All equipment shall have a regular maintenance schedule to assure correct and efficient operation.

The types of markings described as follows are either directly marked on the wire/cable insulation (laser, ink jet, (see SS7334 hot impression stamp) or directly placed on the wire/cable insulation (sleeve markers, wraparound and heat shrinkable insulation sleeving) and they have been directly marked. Recommendation: All direct methods of marking should coordinate wire lengths with wire/ cable spool lengths to assure minimum waste (i.e. short lengths with spool short lengths). An in– line spark tester or similar device is needed to pick up splice locations on each spool.

3.2.1 Laser Marking . A high energy excimer style laser is the preferred type laser to be used on any wire and cable marked at or for Sikorsky Aircraft. The unit comprises a Xenon Chloride excimer laser with beam delivery system, incorporating a simple character generating mask changer, providing high speed automatic changes of code, coupled to a precision cable handling system. Wave length (308nm). The whole system is automated and controlled by an IBM compatible PC. The system employs a non aggressive ultraviolet laser marking to produce a permanent, high quality, high defi-nition cable identification mark while processing cable at high speeds. It is used for marking wire or cable with a primary insulation tape wrap and /or dispersion coating or solid extruded insulation.

It shall be capable of marking wire/cable from 26 ga to 1/4 inch outside diameter. Uses a laser energy density of 1 joule/cm2 for marking. Water cooling – closed loop chiller supplied.

Caution: Xenon Chloride – Gas needs to be changed approximately every 3 months depending on usage. Gas bottle exchange shall require gloves, light suit, face shield and filter mask. Hazard of the gas is within a 2 foot area of the bottle. Proper precautions shall be followed at all times.

Water used to cool the system becomes contaminated/hazardous and shall be disposed of using proper Environmental protection procedures to dispose of it.

3.2.1.1 Yag Laser Marking. A Yag Laser shall only be used IF it has been modified with filters or reducers that convert the laser output from the infrared spectrum down to the ultra violet(UV) spectrum. This will assure that the laser will mark the wire/cable comparable to the excimer laser. Manufacture’s specific instructions and precautions shall be followed to assure that the system will not damage the wire/cable for correct operator interface. Under no circumstance shall the operating system be a discomfort or generate an unsafe or hazardous condition for the operator.

3.2.2 Ink Jet Marking. Shall be capable of marking wire/cable from 24 gage to 1/4 in outside dia. wire size.

3.2.2.1 UV cure – Shall be Autoprint, 350 Mark III UV Ink jet Marking System with Autotreat, and Auto-cure, stations. It shall have in line post print curing, with a maximum machine speed of 200 feet per minute. Lamp lengths from 100mm to 1655mm and outputs from 60W/cm to 180W/cm. Ink jet machine printing velocity shall not exceed 80 ft per minute when using UV cure ink.

3.2.2.1.1 Ink – White UV ink (P/N WT1106) , Viscosity of 3.5cps, 4000 wash, 1120 make up. PF Domino.

Caution: Ink is

Toxic by inhalation and if swallowed May cause sensitization by skin contact Highly Flammable Caution: Wash is Irritating to eyes and respiratory system Flammable Liquid

Unless other-wise specified unjacketed twisted cable shall be identified with TMS sleeves per SS7094 and SS7194. Tie on sleeves see SS7095. Each sleeve marker shall be marked in accordance with the marking requirements of each sleeve markers individual specification. These requirements are the responsibility of Sikorsky and the individual supplier to assure the marking is acceptable on every sleeve that is marked.

3.2.4 Wraparound Sleeves – A integral clear polyester or polyimide tape shall protect and secure a white synthetic label. Sleeves shall be applied using a Getting advance legend entry labeling system #10000. The label shall be a 2“ marking tape capable of 22 characters per line. Diameter range of three different cartridges for applying the sleeves are; 1/8 to 5/16(P/N 1800–2.0), 1/4 to 9/16 (P/N 1850–2.0) and 1/2 to 1 inch (P/N 1950–2.0).

3.2.5 Heat Shrinkable Insulation Sleeving. When specified on the engineering drawing heat–shrinkable sleeves in accordance with SS7072 shall be used for marking. Different sizes are available depend-ing on application. Each sleeve shall be placed on the wire/cable in the locations as identified on the engineering drawing and with the specified marking. They shall be shrunk unless otherwise specified. The size, selection, and shrinking shall be in accordance with the applicable paragraphs in SS7071. Note: if the shrink sleeving is marked using hot stamp marking, each lot/job that is marked shall be tested in accordance with SS7334.

YAG – LASER ONLY – MANDREL WRAP TEST – A 12 inch minimum length of wire shall be sub-jected to four cycles of bending at room temperature for qualification and one cycle for acceptance.

One cycle shall consist of the wire/cable being tightly wrapped against the mandrel winding the wire (5 loops minimum) around a mandrel, specified in Table IV, unwinding and reverse winding the wire (each loop shall be approximately separated at a distance of 3X the applicable wire/cable diameter).

At least one marking pattern shall be on the outside of the wire during the wrapping. After the fourth cycle, the wire shall be checked using 6X to 10X magnification for splitting or cracking of insulation and to assure that there is no exposure of the bare copper wire. Defective wire typically shows cracks starting from “E’s, T’s, I’s, 1’s, f’s and –s under magnification.
