Used to confirm the measurement accuracy of oscillation-type density/specific gravity meters in routine checks and calibrations.
KEM’s range of standards can be used for testing density in the range of 0.69***g/cm3 to 1.49***g/cm3 (at 20°C).
PRODUCT
JCSS Accredited Density Standard Liquid
Features
KEM’s calibration and standard production laboratory is accredited as an ISO/IEC: 17025:2017 and ISO 17034:2016 compliant laboratory by International Accreditation Japan (IAJapan) as a producer of density reference standard materials under the Japan Calibration Service System (JCSS). The JCSS accreditation number for KEM’s calibration and standard production laboratory is 0115.
ISO is an international nongovernmental organization formed by standards bodies representing more than 160 countries and functions to provide a wide range of proprietary, industrial, and commercial standards. Compliance with ISO standards provides assurance of high quality and reliability.
ISO/IEC 17025:2017 specifies the “General requirements for the competence of testing and calibration laboratories”, and ISO 17034:2016 specifies the “General requirements for the competence of reference material producers”.
Upon request, JCSS calibration certificates (recognized under mutual recognition arrangements (MRAs)), can be provided with KEM's density standards at extra cost.
