Points 19 and 20:
Step – I
Selection of fluid class from Group – 1 or Group – 2 (attached chart from the PED file mentions that LCI has selected Group – 2 for jacket as well as shell side fluid).
Step – II
Selection of product category.  
The category chart is enclosed.
From the chart ‘table’ applicable for the fluid group is selected.  In this case, from the fluid group, the applicable tables are 2 & 4.  (Since the ATFE falls under vessel, we have to refer the chart under “based on volumeâ€)
Table no. 2 & 4 are enclosed along with the separate table wherein the multiplication of pressure and volume figures for shell and jacket are indicated for ATFE.  From graph the category I, II,III etc is selected.
Step-III
Based on the category conformity assessment module is selected. Enclosed is the category v/s module chart from the PED file. The module ‘H’ under category III is  the highest which we have selected.  Techno Force has ‘H’ authorization.
We have applied the criteria on both shell and jacket side and the highest one is selected.  The category is  II for 1.5 sq.m. ATFE and III for 8 sq.m. ATFE.
