Copy of Federal Std QQ-Z-325

I am currently updating some old drawings which call out 'ZINC QQ-Z-325, TYPE 2, CLASS 3, 0.005 TO 0.0075 THK AFTER CHROMATE TREATMENT'. This is Federal standard which was withdrawn in 1981 and is therefore not available from the web. Ideally I am hoping someone out there has a copy which they could e-mail or failing that provide information on the coding of the note. For example does TYPE 2 correspond to type II of ASTM B633 and does CLASS 3 correspond to Fe\Zn12 (Service condition 3(severe))?

I want to know if Zinc Plated per QQ-Z-325 type 1 class 3 is RoHS compliant.
