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.
