Scope

This document describes the method for determining the phosphorus content in rare earth iron alloys (lanthanum iron alloys, cerium iron alloys, lanthanum-cerium iron alloys, neodymium iron alloys, dysprosium iron alloys, gadolinium iron alloys, holmium iron alloys, and yttrium iron alloys).
This document is applicable to the determination of phosphorus content in rare earth iron alloys (lanthanum iron alloys, cerium iron alloys, lanthanum-cerium iron alloys, neodymium iron alloys, dysprosium iron alloys, gadolinium iron alloys, holmium iron alloys, and yttrium iron alloys). The measurement range (mass fraction): 0.005% to 0.20%.
