Standard tests for determining compatibility of cable-pulling lubricants with wire and cable
|Publication Date:||1 January 1996|
This standarda pplies to cable pulling lubricants (compounds) and the testing and analysis of their interac tion with wire and cable Cable pulling lubricants are used to lower the tension on cables when they are installed (pulled) into conduits ducts or directionally bored holes These lubricants and/or their residues are in direct contact with the cable exterior covering and may remain so for the life of the cable Cable-pulling lubricants should be compatible with the cable They should not interfere with the function of any compo nent of the cable system that they contact.
Compatibility of cable pulling lubricants with cable coverings is the only subject of this standard other important performance criteria for cable-pulling lubricants such as friction reduction toxicity combustibil ity, etc., are not discussed.
This standard utilizes accepted cable performance standards whenever possible. Relevant standards are cited in the text and listed in clause 2.
This standardd escribest ests for determining the compatibility of cable-pulling lubricants with cablej acket or other exterior cable covering. Compatibility of cable-pulling lubricants with a variety of common cable coverings is considered.
Often, testing is confined to the effect of the lubricant on the physical properties of the jacket. When the electrical properties, such as dielectric withstand voltage or electrical resistivity, are important, the evaluation also includes these properties.
