  • Addressing and closing nonconformity regarding clause 7.2

    We have an NC regarding clause 7.2, how do I address it and close it?

  • Document control

    When update quality system, if we have a stock of printed forms with a code for example "lab(5) form". In new document we change the coding system for example 6-4-01. Can we use the old form although it has a cod with different system. or it is acceptable to change the code on each form manually?

  • Clause 6.4.3

    "Under clause 6.4.3 within 17025, I have a question regarding a requirement or not if there is a requirement for a test for residual detergents? This is regarding the cleaning of glassware within microbiology.

  • Glassware cleaning within microbiology labs

    Section 6.4.3 - Requirement: The procedure and/or supporting procedures include instructions to ensure that equipment, media, reagents, test organisms, etc. are handled, transported, stored, and used in a manner to ensure proper functioning and to prevent contamination or deterioration.

    Question - When washing and reusing glassware that can impact the recovery of organisms, does the laboratory require a procedure to test for residual detergents ? Is this mandatory or purely a best practice ? for example: Bromthymol Blue Solution (0.04% Aqueous Solution (Caledon #LC 12050-1) or equivalent) is used once a month to verify the complete removal of detergent traces by the rinse cycles and used whenever new detergents are introduced. Should a test such as this be written in to the SOP ?

  • Measurement uncertainity

    We are curtain wall, doors and windows performance testing laboratory. The representative sample of the door or windows (consists of aluminium profiles, glass, etc.) are installed in the lab as closed chamber. Resistance of the system to air, water and wind load are analysed by varying the pressure of the system. The range of pressure (negative and positive pressure) are as per the project specifications. We do the testing as per international standards (ASTM, CWCT, AAMA, BS) only. We have rotameters, pressure gauges, deflection gauges and water spray nozzle as the measuring instruments. All of them are externally calibrated. Final result are recorded as either passed or fail.
    Is measurement of uncertainty applicable for our scope of work? what are factors to be considered if we requires to calculate the same? can you suggest some tools for the calculation?

  • 8.5 Actions to address risks and opportunities (Option A) (new)

  • What do I need to become a NRTL?

    Our customer frequently ask us to perform a calorimeter on the HVAC compressors we sell to them. Typically we have the factory do this for free but the factory is in Korea, so this takes time. So we then started to consider getting our own machine and doing the test ourselves. That quickly migrated to getting NRTL and purchasing a psychrometric room in addition to the calorimeter. So my question is what do I need to become a NRTL, I'm seeing that I would need accreditation from an A2LA or similar organization. And if I am understanding this correctly we would need ISO 17025 to get the accreditation. So my question is am I understanding this correctly? I hope this made sense its a long story and I am sure you don't want all the crazy details. Any help or advise you can give would be appreciated.

  • Environment microbial limits

    I was searching the net to find out the environment microbial limits. For ISO purposes, could we create our own limits?
