Theoretical factors.
- Calculated worst case gasket compression based
on manufacture tolerances to be checked as a quality
control provisions.
- Calculated or measured flange defecting based on
nominal draw down. Worst case flange areas.
- Designate field adjustment/wear points and estimate
end-of-life effects.
- Support choice of gasket in terms of
1 electrochemical activity
2 compression set
3 compression range
4 manufacturers part number or specification
5 transfer impedance data and or wear characteristics,
if availlable
- show that with worst case manufacturing and field
tolerances and a given choice of gasket, that gasket
remains within recommended compression range within
entire door surface.
- Review decorative escucheon design feature and
choice of a filter foam. Also review latch handle.
2 P̲R̲O̲T̲O̲T̲Y̲P̲E̲ ̲D̲O̲O̲R̲
Performance Factors.
- Smooth operation. No binding scraping or hang up
for 50 successive closures without adjustment or
other maintenance operations.
- Reasonable operating force to engage and draw down
the latch.
- Demonstrate door lift-off capability
- Reinstall door without further adjustment
- Demonstrate smooth operation or 50 more operations
- Demonstrate that door is impressing gasket in a
worst case spot chosen by customer or representative
either with measurement or with plastic gange.
- Demonstrate that compression set of gasket compared
with "near new" is less than 25% of incompressed
height when "near new"
- Demonstrate that gasket stays in adjustment, or
in channel over operations.
- Perforated metal/decorative escucheon design feature

Use of specified materials
gasket
base material of rack (thickness)
perforated metal type.
Built to approved print (prints should designate any
approved alternative process or material)
Check important tolerances
- for gasket performance
- for form/fit/function
Check workmanship
- weld quality and grinding
- plating or metalizing of gasket surface
Check smoothness of door operation
Check appearance
- paint finish, color, texture, fl HVAD SKAL ST<
HER??
Check accessories and packing crate.
