This specification covers the application of external wire bundle protection on new uninstalled designs or the repair and additional protection of a cable, harness or wire bundle with protective sleeve in installed designs. Significant coverage of the installed cable, harness, or wire bundle should not be performed without taking the following into consideration.

a. Design control authority.

b. Temperature rated sleeve compared to the rated temperature of the wire, cable, or bundle being covered.

c. For installed wire bundles, the jacket repair or scrape abrasion sleeve is intended to be used only as a localized application where the cable or bundle jacket or hazard areas need further protection. The wrapping of a sleeve over significant portions of the bundle surface may affect previous engineering design such as internal temperature rise of the bundle especially at altitude, etc. Use of the sleeve for complete protection of a significant portion or all the bundle area requires engineering considerations not addressed by this specification.

d. Sleeve is not intended for fire zone application without engineering consideration.

e. The sleeve with an internal shield may be used as a localized application where the shielded cable has been damaged, but using it extensively for electromagnetic or radio interference protection on installed wire groups requires engineering design control.

f. Sleeves with a shield should not be used in fluid exposed areas without engineering considerations.
