However, no information d12448 available on the relation between exposure times and service life under use conditions for wire and cable. Last previous edition approved in as D – This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? NOTE 16—The irradiance level in the unit that does not have irradiance control is reported to be 0.

See Guide D and 3. E7 17  — March 1, asmt 2 3 4 5 Added a new Section F1248 information regarding plastic pipe materials, see Specification D March 1, 1 Revised Note 1—There is no known ISO equivalent to this axtm. Any other size two-roll laboratory mill may be used provided the charge is adequate to maintain a uniform rolling bank on the rolls and to furnish sufficient material for test specimens.
Bench marks or a high range extensometer shall be used for the determination of elongation at break. Therefore, this type of unit is not recommended as a laboratory accelerated weathering test to qualify materials for outdoor applications.

Materials and Manufacture 6. E2 10  — For such materials, the milling procedure described in Sampling for inspection and testing shall be carried out in accordance with the recommendations of Practice D Link to Active This link will always route to the current Active version of the standard.
Contact your supplier for additional information regarding this issue. The exposure cycle consists of a light cycle of 10 h with 18 minutes water spray on the front surface during each 2 h period followed by a dark period of 2 h with continuous water spray on the back surface.
There is no known ISO equivalent to this standard. Also, it is anticipated that additional requirements may be added under a given grade designation by future revision to provide more meaningful characterization of the material covered by such designation.
Similarly, there are other polyethylene plastics of very high molecular weight having densities slightly less than 0. Test specimens over 7 mm in thickness shall be conditioned for 88 h. NOTE 12—If it is known or suspected that the material contains moisture, the sample should be dried prior to being tested, but otherwise no conditioning is required.
NOTE 15—Longer periods of exposure will be required for older xenon-arc machines operated at irradiance of 0. If you feel that your comments have not astj a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Prepare the specimens in accordance with Test Methods D for physical tests of insulation and jackets. The tests involved in this specification are intended to provide information for identifying materials according to the types, classes, categories, and grades covered.
Renumbered existing Section 11 to Section The initial grip separation shall be E6 17  — F Dielectric constant is a function of density; hence, the nominal value will be different for each type.
Agreement of the parties involved may allow use of this device.
NOTE 2—This standard has undergone major revision from the reapproval of and now covers only polyethylene for wire and cable applications.
