Good day to all,
I am in my 3rd monthg of a new role as a supervisor and i have noted that the internal facility checks specifically SCALES are checked using a couple of old weights (to which i have not found a certificate for) and with those checks there isnt specified a tolelrance for each balance used.
By this i mean:
Scale A) UWE ADM 6000 Max 600g min 40g:
so what weights should be used to test this is working and what tollerance? 2 KG weight tollerance or +-2g? or should certain weights be used with a tollerance of a specific +- t odetermine if its out of spec? and not fit for use?
---Scale used for weighing product to 450g only---
T-scale T-130 Max 600KG x 0.1g Floor scales at moment are not being checked daily (used for weighing waste only) and i think a a matter of GMP we should be and if i use say a 10kg weight would this be ok? what would the tolerance be for out of spec? +- 2kg? i dont know...
uwe am-15k min 100g max 15kg This scale is used for weighing finished boxed product 7kg 8kg and 9kg only. Curently using 2kg weight with a 5 kg weight and again there is no tollerance on thew sheet to define if its in spec or not so what would this scale be? +-2g? again im not sure.
finnaly STW-150ke max 150kg x10g this scale does not weigh end product but is used for weighing trays of product at a particular process step which is not a CCP i might add but again we use a 2 kg and 5 kg weight but no tollerance to define what is out of spec.
I have worked through 2 yrs back log of old calibration records with no out of spec recorded and although the scales since i have worked here have always read the same as the weights declared im not happy that i do not have a tolelrance to work by like we do with temperature probes.
I guess the 1st step is to send my weights off to get calibrated. but how do i go about the tollerances for the daily calibration checks?
I mean im not even certain the weights we are using are the right ones for the types of scale we are using.
The scale Guiy is coming out in june to do his annual checks and i have a million questions for him but it just seems that with BRC also due in june im concnerned this might be flagged as an issue..
any help advice welcome and appreciarted.
