Web Sling Design Factor

After web nominal strength has been adjusted by applying the fabrication factor, the sling’s rated capacity is then determined by using a design factor of 5 to 1, as specified by American National Standards Institute (ANSI) standard ANSI B30.9, Section 9 - 5.2. ANSI and OSHA both require sling manufacturers to document published sling ratings with records of test data.
