Preparation of middle-low alloy steel chemical compositonsample for proficiency testing and discussion onhomogeneity test procedures

The selection and preparation of proficiency testing samples, which have good homogeneity and same or similar test level and matrix with those of routing inspection samples, is always the key to successfully carry out the laboratory proficiency testing activities. Through the operation and implementation of middle-low alloy steel proficiency testing projects with typical significance, the general principles and methods for sample selection, processing, preparation and homogeneity test were discussed and proposed. Moreover, the related issues in preparation and homogeneity test of middle-low alloy steel sample for proficiency testing were discussed. The study provided certain help and guidance for the persons who engaged in proficiency testing.
