• ASTM Class 0: used as primary reference standards for calibrating other reference standards and weights.
• ASTM Class 1: Can be used as a reference standard in calibrating other weights and is appropriate for calibrating high precision analytical balances with a readability as low as 0.1mg to 0.01mg.
• ASTM Class 2: Appropriate for calibrating high-precision top loading balances with a readability as low as 0.01g to 0.001g.
• ASTM Class 3: Appropriate for calibrating balances with moderate precision, with a readability as low as 0.1g to 0.01g.
• ASTM Class 4 - For calibration of semi-analytical balances and for student use.
• NIST Class F - primarily used to test commercial weighing devices by state and local weights and measures officials, device installers and service technicians. Class F weights may be used to test most accuracy class III scales, all scales of class III L or IIII, and scales not marked with a class designation. Calibrated according to NIST Handbook 105-1
• OIML Class E1 - Used as primary reference standards for calibrating other reference standards and weights.
• OIML Class E2 - Can be used as a reference standard in calibrating other weights and is appropriate for calibrating high precision analytical balances with a readability as low as 0.1mg to 0.01mg.
• OIML Class F1 - Appropriate for calibrating high-precision toploading balances with a readability as low as 0.01g to 0.001g.
• OIML Class F2 - For calibration of semi-analytical balances and for student use.
• OIML Class M1, M2, M3 - Economical Weights for general laboratory, industrial, commercial, technical and educational use. Typically fabricated from cast iron or brass. Class M2 commonly used for student brass weights.
