Why Redline?

A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.

With a redline you'll immediately see:

Save Time and Trouble!

With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.

Price

When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

Annotation of standard text ASTM D1430-22 :

This classification system covers polychlorotrifluoroethylene (PCTFE) plastics that consist of at least 90% chlorotrifluoroethylene and are suitable for extrusion and for compression and injection molding. The remaining 10% may include chemical modifications, such as co-monomers, but not colorants, fillers, plasticizers, or mechanical blends with other resins. PCTFE materials in powders and pellets are classified into one group. The group is subdivided into classes based on chemical composition: Class 1; Class 2; and Class 3. These classes are subdivided into grades: Grades 1, 2, 3, and 0; Grades 1, 2, and 0; and Grades 1, 2, and 0; respectively. The molding or extrusion material shall be of uniform composition and so compounded as to conform to the requirements of this classification system. The properties shall be determined in accordance with the following test methods: conditioning; zero strength time; test conditions; deformation under load; melting point; dissipation factor and dielectric constant; and specific gravity.
