*The minimum weight (typical) U=1% represents the minimum weight required to meet 1% uncertainty under ideal metrological conditions. Uncertainty of U=1% is not valid to meet USP Chapter 41 requirements, but may be acceptable for other applications.
**USP Chapter 41 is a mandatory United States Pharmacopeia standard. Min-Weight (typical) U=0.10% as listed in the data sheet is to be used as a comparative reference only. The actual minimum weight must be calculated using an on-site repeatability test under actual use conditions. Refer to USP Chapter 41 for more information.
