  The ESS-Bil­bao RFQ is an as­sem­bly of four seg­ments, each one about 800 mm in length. The first seg­ment has been man­u­fac­tured be­fore the oth­ers, so it could be thor­oughly tested in order to val­i­date the cho­sen tech­no­log­i­cal ap­proach for the RFQ, as it uses poly­meric vac­uum gas­kets and bolts in­stead of braz­ing. In this paper we re­port on the tests run with the seg­ment and their re­sults. Vac­uum tests, metrol­ogy mea­sure­ments, low power RF tests as well as ex­ten­sive tun­ing tests mea­sur­ing the cav­ity res­o­nant quadrupo­lar fre­quency as a func­tion of cool­ing water tem­per­a­ture have been done. Ex­per­i­men­tal re­sults are com­pared to the ex­pected val­ues ob­tained from nu­mer­i­cal sim­u­la­tions. We de­scribe the ex­per­i­men­tal set-ups for the mea­sure­ments and the sim­u­la­tions. Re­sults are an­a­lyzed with the aim of val­i­dat­ing the de­sign, and also to pro­vide pre­dic­tions for tun­ing and op­er­a­tion of the whole RFQ. As a con­se­quence of the pos­i­tive re­sults of the tests re­ported here, the re­main­ing seg­ments have al­ready been ten­dered.
