There are no specific test standards for AD 2000 B 7 Gasket Parameters. However, an estimation is provided below. The 2015 edition of "AD 2000-Merkblatt B 7" refers to EN 13555 as a test standard(1) and uses table 9 from VDI 2200(2) for the conversion method. Please note that VDI2200 states that such a conversion is invalid due to the different measurement methods. "Only the method according to DIN EN 1591-1 and AD 2000 in conjunction with DIN EN 1591-1 and FE analysis can be used for providing stability, leak tightness and TA Luft proof." (3)

If necessary for a specific application, Gore recommends to do individual conversions based on data from EN 13555.The use of the general values given in table 1 of AD 2000-Merkblatt B 7(5) is not broadly recommended. However they may be applicable depending on the given situation.Please also note that the quoted standards of DIN 2690 to DIN 2692 were superseded by EN 1514-1 in 1997.

The table below shows some standard valve dimensions. The breather valve can be adapted to the specific requirements for the application as desired. All our valves fall under the category of normal directly operating weight-loaded safety valves according to AD 2000 Merkblatt A2.
Snow gliding in 1998/1999 and 1999/2000 was characterized by a differing trend. While on measuring zone 2 (open forest) and 3 (dense forest) the frequencies in class 1 were higher than in class 2, the frequencies on the remaining measuring zones do not indicate a clear difference between class 1 and class 2 (in 1999/2000 the glide rate frequencies on measuring zone 4 and 6 were even higher in class 2 than in class 1). It was assumed that the deeper snowpack in 1998/1999 and 1999/2000 caused higher frequencies in class 2 (except on measuring zones 2 [open forest] and 3 [dense forest] where, because of the lower snowpack in the forest, a contrary trend was identified). 2ff7e9595c
