ISO/IEC 17025 and ISO 17034 Diesel (Synthetic) Sulfur Certified Reference Material (CRM) Kit, ASTM D7220, Calibration Set A intended to be used for calibration or verification of measuring equipment, method validation, method verification, or other quality control processes applicable for analysing sulfur content in petroleum products, typically used in, but not limited to test method ASTM D7220 or other applicable methods. The sulfur calibration kit includes Blank, 0.0005 % (5 mg/kg), 0.0010 % (10 mg/kg), 0.0025 % (25 mg/kg), 0.0050 % (50 mg/kg).
Each Sulfur CRM provides traceability of measurement to recognised national standards, and to units of measurement realised at the National Physics Laboratory (NPL) or other recognised national standards laboratories. All sulfur content values are traceable to National Institute Standards and Technology (NIST), and each CRM provides accurate levels of uncertainty, ensuring maximum accuracy of data at hand.
