Rationale: AMS4899D results from a Five Year Review and update of this specification that includes the removal of sample size allowance for hydrogen of Table 1 (covered by ASTM E1447), requires agreement on mechanical property values for material outside specification ranges (188.8.131.52), requires ultrasonic testing of all plate 0.500” and over (3.6.1), the addition of AS6279 (3.8), adds AMS2368 in sampling and resampling (4.3 and 4.5) and revises the report paragraph (4.4).
