ASTM D2903-11

Standard Specification for Crosslinked Chlorinated Polyolefin Heat-Shrinkable Tubing for Electrical Insulation

ABSTRACT
This specification covers the manufacture, testing, and property requirements of two types of flexible crosslinked chlorinated polyolefin heat-shrinkable tubing used for electrical insulating purposes. It is supplied in an expanded form and will shrink to the specified diameter when heated. Type I tubing is used for normal operating temperatures, while Type II tubing is used for extended operating temperatures. The finished compound shall be free of foreign matter other than antioxidants, flame retardants, processing aids, crosslinking agents, pigments or other additives as appropriate. The final tubing shall be extruded, crosslinked and then expanded to the required dimensions. Specimens shall be sampled and tested accordingly for the following properties: corrosion by copper mirror and copper contact test; solvent resistance by immersion in Grade JP-4 fuel, lubricating oil, hydraulic fluid, sodium chloride solution, anti-icing fluid, and aviation gasoline; flammability (time of burning and burning distance); water absorption; and tensile strength, ultimate elongation, and weight increase.
SCOPE
1.1 This specification covers flexible crosslinked chlorinated polyolefin heat-shrinkable tubing used for electrical insulating purposes. It is supplied in an expanded form and will shrink to the specified diameter when heated.
Note 1—This standard does not have a similar or equivalent IEC standard.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.2.1 In some cases, temperatures are described in degrees Celsius only.
