The major performance characteristics that have changed from the old standard to the new are the removal of those for Type II Static Dissipative and Class 30 for impact and compression requirements. As a result, the significant majority of protective footwear that met ANSI Z41 PT99 will now meet the new ASTM F2412-05 and F2413-05. All of the protective footwear that Tyndale sells meet the new ASTM standard.
