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 storage 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 uncertainty is the expanded uncertainty estimated in accordance with ISO 17034 with a coverage factor k=2,corresponding to a level of confidence of about 95%.

Measurement traceability:

Traceability to SI has been established through an unbroken chain of comparisons each having 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 ee contact. ingestion or inhalation.
