    The prototype for the series production of the 400 modules to be built by CNIM is first briefly described after the surface cleaning and 400 degrees C air firing. The systems for the 160 degrees C bake out, the pumping and measuring bench installed in the CNIM premises are then presented. The results on leak tightness, hydrogen outgassing and residual hydrocarbon contamination are reported and compared to the 20 degrees C VIRGO specifications. An additional test on hydrogen diffusion at 400 degrees C performed at CERN on a stainless-steel sample is reported. Our measurement of the hydrogen outgassing rate is discussed in relation with this test and also with regard to the oxide layer resulting from the air firing. (5 refs)
