A QMS for a food retail establishment will require to have food safety as a mandatory process. Please find what the US food code says about temp control. If a dishwshing machines has performance criteria listed below, do you think a calibration is not required. Please do give your opinion.A dish washer being calibrated? :mg: If we don't apply ISO 9001 with common sense, we are only helping the detractors of the standard.
PS. This is a very old thread.

(B) The temperature of the wash solution in spray-type
warewashers that use chemicals to SANITIZE may not be less
than 49oC (120oF).
4-501.111 Manual Warewashing Equipment, Hot Water
Sanitization Temperatures.*
If immersion in hot water is used for SANITIZING in a manual
operation, the temperature of the water shall be maintained at
77oC (171oF) or above.
4-501.112 Mechanical Warewashing Equipment, Hot
Water Sanitization Temperatures.
(A) Except as specified in & (B) of this section, in a mechanical
operation, the temperature of the fresh hot water SANITIZING
rinse as it enters the manifold may not be more than 90oC
(194oF), or less than:
(1) For a stationary rack, single temperature machine, 74oC
(165oF); or
(2) For all other machines, 82oC (180oF).
(B) The maximum temperature specified under ¶ (A) of this
section, does not apply to the high pressure and temperature
systems with wand-type, hand-held, spraying devices used for
the in-place cleaning and SANITIZING of EQUIPMENT such as
meat saws.
4-501.113 Mechanical Warewashing Equipment,
Sanitization Pressure.
The flow pressure of the fresh hot water SANITIZING rinse in a
WAREWASHING machine may not be less than 100 kilopascals
(15 pounds per square inch) or more than 170 kilopascals (25
pounds per square inch) as measured in the water line
immediately downstream or upstream from the fresh hot water
SANITIZING rinse control valve.
