Foreword
This standard was drafted in accordance with the rules of GB/T 1.1-2009 and GB/T 20000.2-2009 given.
This standard uses redrafted Law Amendment uses ISO 28763.2008 "enamel for air - smoke, smoke - smoke regenerative heat exchanger
The enamel heat transfer element specification "(in English).
This standard and ISO 28763. Compared to 2008, the main differences are as follows.
--- Standard name changed to "for air - smoke, smoke - smoke enamel heat regenerative heat exchanger element";
--- The "this International Standard" be replaced by "this standard";
--- Remove the ISO 28763.2008 foreword, preface this standard increases and directories;
--- For the ISO 28763.2008 normative international documents referenced file instead of using the applicable country, where there is no applicable text of
Member, direct technical content into normative appendix of this standard;
--- Adjust the structure of the text, and ISO 28763.2008 corresponding to the structure of the table in Appendix A.
