SEMI F7 - Test Method to Determine the Tensile Strength of Tube Fitting Connections Made of Fluorocarbon Materials -
This standard was technically approved by the global Facilities Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee in October 1998. It was available at www.semi.org in February 1999. Originally published in 1992.
NOTICE: This Standard or Safety Guideline has an Inactive Status because the conditions to maintain Current Status have not been met. Inactive Standards or Safety Guidelines are available from SEMI and continue to be valid for use.
This method provides a uniform procedure to determine the tensile strength of tube fitting connections made of fluorocarbon materials.
This method can be used to characterize tube fitting 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 fluorocarbon materials.
All parts of the tube fittings tested by this method in contact with the internal fluid are made of fluorocarbon materials.
Parts such as a nuts or grippers are not limited to being made of a fluorocarbon material.
Only the seal between the tube and tube fitting being evaluated 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 tube fittings and/or manufacturers, the user must be specific in the selection of the tube and tube fittings 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.
