It is the responsibility of the user asgm this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Other grades may be added as necessary by revision of this speci? NOTE 16—The irradiance level in the unit that does not have irradiance control is reported to be 0.

The initial grip separation shall be 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. Test results for specimens that break outside the gage-marks after extensive cold drawing need not be discarded unless the break occurs between the contact surfaces of a grip.

A number in parentheses indicates the year of last reapproval.

NOTE 4—It is recognized that some high-density polyethylene plastics of very high molecular weight may have densities slightly less than 0. Link to Active This link will always route to the current Active version of the standard. The letters associated with these grades identify areas of potential applicability as indicated below: NOTE 17—It should be noted that the irradiation spectra from different sources including carbon arc, xenon arc, and UV?

A superscript epsilon e indicates an editorial change since the last asmt or reapproval. The melt viscosity of polyethylene plastics, in common with that of most high d11248, is non-Newtonian, that is, dependent on the rate of shear. For information regarding molding and extrusion materials, see Specification D NOTE 14—The h exposure period speci?

Solution viscosity is recommended as a means of distinguishing such materials. The former is the criterion for assignment as to type which are as follows: It is not the function of this specification to provide specific engineering data for design purposes.

Deleted the existing paragraphs 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 s1248 on the back surface. The following terminology is in use in ASTM speci?

NOTE 15—Longer periods of exposure will be required for older xenon-arc machines operated at irradiance of 0. By means of our testing expertise and modular product design, we will help find the solution that is right for you.

NOTE 8—Tables 4 and 5, are included to correspond with the grades speci? March 1, 1 2 3 4 5 Added a new Section In the absence of contrary requirements, the following values shall apply: V1248 offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for aztm applications.

It is not the d148 of this speci? E At any frequency from 1 kHz through 1 MHz see also E5 12 [] —75 Different tests shall be conducted in order to determine the following physical properties of extrusion materials: Rather, the material is to be checked initially for compliance with this requirement and, after that, as often as necessary to assure continued compliance.
