CERTIFICATE OF ANALYSIS

Instructions for handing and correct use

The RM should be equilibrated to room temperature and shaken prior to use.The concentration with its uncertainty is guaranteed in the range between(20±4)℃.The expiry date is valid for original sealed bottles under recommended sto rage conditions only. Open slowly and carefully to avoid dispersion of the material.

Intended use:

For laboratory analysis only,not for drug,household or other uses.

Uncertainty:

The reported uncertaintv is the expanded uncertaintv estimated in accordance with ISO 17034 with a coveraae factor k=2corresponding to a level of confidence of about 95%.

Measurement traceability:

Traceability to SI has been established through an unbroken chain of comparisonseach having stated uncertainties.Al I Traceabilitv to SI has been established throuah an unbroken chain of comparisonseach havina stated uncertainties.
All analytical balances and Class A glassware used in manufacturing and quality control are calibrated by an accredited calibration laboratory.

Safetyinformation:

Treat as hazardous substance.Use appropriate work practices when handling to avoid skin or eve contactingestion or inhalation.
