Measurements of magnetic flux density in the vicinity of transformer station

According to ISO/IEC 17025 [1] standard the laboratory shall have quality control procedures for monitoring the validity of tests undertaken. Quality of test results can be controlled by participation in interlaboratory comparison programs. The firm Centar za mjerenja u okolišu d.o.o. has organized interlaboratory comparison of results obtained by measurements of magnetic fields in the vicinity of a compact concrete-housed transformer station located in Zagreb, Croatia.
