In 2009 CEPT asked ETSI_ERM_TG34 to improve the test method for tags that is specified in clause 10 of EN 302 208-1 V1.2.1. This was to ensure that the standard complies with the guidelines in ERC Rec 74-01. At about the same time ERM_TG34 also received a request from the German administration to amend the method of test for interrogators. Their objective was to ensure that no spurious noise could be emitted during the switch-on and switch-off of transmissions from interrogators.
