There seems to be a difference in requirements of the intensity tolerance in AMS 2430 revision S and J443 revision 2010.
In section 3.10.2 of the former the following is specified:
Intensity verification test strip measured arc heights shall be reproduced within +-0.0015 inch (0.0375 mm) of the process parameter sheet and shall be within the intensity range for the part.
Whereas in section 7.3 of the J443 the following is specified:
... The resulting arc height readings must then repeat the value achieved in the corresponding original saturation curve +-0.038 mm (+-0.0015 in). The resultant arc height readings do not have to be within the intensity tolerance band since the single verification time at a given location may be substantially less than or greater than T...
The AMS 2430 is more stringent, but at the same time it refers to J443 for the intensity verification method (see AMS 2430 sections 3.2.2, 188.8.131.52 and 184.108.40.206). By doing that it seems that the AMS 2430 accepts the J443 interpretation as well. How to interpret this?
