Straw Man: This document is a starting point for future drafts and is not an approved document. Please do not distribute to laboratory staff for use.

B: Autoclaves equipped with a calibrated temperature sensing device that provides a record of temperature are considered as meeting this requirement. C: All weights and balances shall be calibrated traceable to recognized national or international calibration units (i.e., National Institute for Standards and Technology (NIST), Bureau International des Poids et Mesures (BIPM), Organisation Internationale de Metrologie Legale (OIML), or equivalent traceable weights). Accrediting bodies may require calibration by an ISO17025 accredited calibration laboratory. D: . For quantitative methods, an analytical standard at the mid-range or lower of the calibration curve can verify detector response. For qualitative assessments, the appropriate response material must be used. E: When pH or water activity results are reported to the customer or may be a significant component of overall uncertainty of the measurand, the reference material (e.g. buffer or water activity analytical standard) must satisfy the requirements for metrological traceability (clause 6.5.1). Accreditation bodies may require buffers obtained from ISO17034 accredited manufacturer. F: The intent is the laboratory must be able to verify samples were stored at proper temperature for the duration of storage. Continuous monitoring with a calibrated and validated system meets this requirement. A min/max data logging thermometer would require verification at a frequency dependent upon the amount of data it can store. G: When determining mapping schedules, attention should be paid to extremes in laboratory ambient conditions (such as those brought on by seasonal changes) that can influence the performance of equipment. The annual uniformity mapping should be done with load (e.g., while in use). Initial and non-routine maintenance monitoring can be done with no load. H: Timers and internal timing devices only need to be verified when time is a critical factor in the test method. Time may not be a critical factor when time is not the reported result or a precise time is not required for the test method.

I: Accrediting bodies may require initial calibration by an ISO17025 accredited calibration laboratory.

J: Continuous monitoring with a conductivity meter calibrated at a frequency consistent with this table will meet this requirement. Continuous monitoring with a sensor that is not calibrated does not meet this requirement (for example, an indicator light on the DI tank).
