Note 1—There is no known ISO equivalent to this standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This standard has undergone major revision from the reapproval of and now covers only polyethylene for wire and cable applications. This is discussed in Practice D This specification provides for the identification of polyethylene plastics extrusion materials for wire and cable in such awtm manner that the seller and the purchaser can agree on the acceptability of different commercial lots or shipments.

E2 10 [] — Asfm polyethylene plastics are identified primarily on the basis of two characteristics, namely, density and flow rate previously identified as melt index. Perform the tests in accordance with Practices GGand D using the following exposure conditions: NOTE 6—Carbon black 35 nm or less in average particle diameter is used as required in black electrical and jacketing materials Grades E and J to impart maximum weather resistance.

Additional characterization of the sample can be obtained if other conditions are used. After being milled as prescribed, the material shall meet the dielectric requirements prescribed adtm Table 3.

The following additional instructions and the precautions of Note 12 shall be observed: NOTE 2—This standard has undergone major revision from the reapproval of and astn covers only polyethylene for wire and cable applications.
