VWR®, Relative Density standards within the range of 15 to 25 °C
标准品 Density Standards
This range of relative density standards are certified in accordance with primary level ASTM D1480 methodology, and are dual-certified to ISO 17025 / ISO 17034 under UKAS accreditation. Relative Density standards are designed for the calibration or verification of instruments used to measure density and relative density of materials at the desired test temperature within the range of 15 to 25 °C.
- Certified in accordance with primary level ASTM D1480 methodology
- Full traceability to national standards
- Supplied in tamper-evident packaging with a 2 year shelf life
Relative density is calculated by dividing the density, as obtained from ASTM D1480, by the density of water at the reference temperature.
The density of water was taken from the table 'Density of Water' found in ASTM D1480 and confirms to the International Temperature Scale (ITS 90).
Certifications: Dual-certified to ISO 17025 / ISO 17034 under UKAS accreditation
Caution: The density given in the ordering table below is the nominal relative density value - actual batch values are given in the certification documents supplied with the product and also on the label.
