Graded Height Tolerance

Graded Height Tolerance

Graded Height Tolerance = (((# Strands/2)+3.5)/1000) x Graded Factor x Temper Factor

Graded Factor is for Strand Sizes

 ≤

0.080 x 0.300” (2.03 x 7.62mm) = 1.0
 

 ≤

0.120 x 0.300” (3.05 x 7.62mm) = 1.5
 

 ≤

0.100 x 0.492“ (2.54 x 12.0mm) = 2.0
 

 

0.120 x 0.492“ (3.05 x 12.0mm) = 2.67

Temper Factor is  ≥ 9W & ≤ 20,000PSI (140N/mm²) = 1.0
   < 9W & > 20,000PSI (140N/mm²) = 1.2
