SEMI C83 - Test Method for Tensile Strength Applied to Welded Connections Made by PFA Weld Fitting -

Abstract

This Standard was technically approved by the Liquid Chemical Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on June 4, 2013. Available at www.semiviews.org and www.semi.org in July 2013.

　

This method provides a uniform procedure to determine the tensile strength applied to welded connections made by PFA weld fitting.

　

This method can be used to characterize welded connections on the basis of test data developed under the conditions described herein, but the results are not intended to imply a performance rating.

　

Tube defined in this method has a circular cross section and is made of PFA.

　

Welded connections tested by this method are made by PFA weld fitting.

　

The seal between the tube and the welded fitting and between the welded fitting and the welded fitting is within the scope of this Document. All other, threaded seals are beyond the scope of this Document.

　

When using this method for making comparisons among various welded fitting designs and manufacturers, the user must be specific in the selection of the tube and welded fitting s to be evaluated.

　

The International System of Units (SI) is used as the standard unit of measure in this Document. The U.S. Customary units are in parentheses for reference purposes only and have been rounded to the nearest whole value.
