Instructions for handing and correct use:

The RM should be equilibrated to room temperature and shaken prior to use. The concentration with its uncertainty isguaranteed in the range between (20 ±4)'℃. The expiry date is valid for original sealed bottles under recommendedstorage 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 factork=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.Allanalytical balances and Class A glassware used in manufacturing and quality control are calibrated by an accreditedcalibration laboratory.

Safety information:

Treat as hazardous substance. Use appropriate work practices when handling to avoid skin or eye contact,ingestion orinhalation.
