In order to calibrate radiation protection instruments and determine radiation dose, it is critical to establish an X-ray narrow-spectrum series recommended by the standard ISO 4037-1 which is published by the International Standardisation Organisation (ISO). By experiment, the qualities of filtered X radiation of narrow-spectrum series in the range from 60 to 300 kV were established. The differences of the first half-value layer (HVL1) and the second HVL (HVL2) between experimental results and the values given in the standard ISO 4037-1 were all within 5%. What is more, the Monte Carlo code EGSnrc was used to simulate the spectra of these radiation qualities, which showed a good agreement with these spectra given in the standard ISO 4037-1. The spectral resolution, mean energy and effective energy of these reference qualities can be obtained, which are all have good agreement with the given values.
