SODALIME TEMPERED GLASS PANES TYPE A - ISPESL M.15.C AND CTI ADVISE

Sodalime Tempered Glass Panes Type A

The ISPESL M.15.C standard applies to pressure resistant circular panes for sight glasses made of thermally toughened sodalime glass, which are designed to withstand a continuous one-sided fluid pressure at temperature between -200°C and 150°C this limit decrease to 100° in case of fluids having PH larger than 7,5.
