With its robust construction, controlled magnetic susceptibility, and certified calibration, the M1 Class 500g weight is ideal for organizations seeking dependable and audit-ready mass standards.

Material & Finish of M1 Class 500g Weight for Long-Term Stability

The M1 Class 500g weight is manufactured from high-grade austenitic stainless steel (SS-316), ensuring excellent corrosion resistance and dimensional stability over time. The single-piece, knob-type cylindrical bar design eliminates assembly joints, reducing the risk of mass variation due to wear or contamination.

Key material characteristics include:

• Material: Austenitic Stainless Steel
• Design: Knob type cylindrical, single-piece bar
• Density: 7950 (±140) kg/m³

This optimized density and polished finish ensure minimal surface oxidation, easy cleaning, and consistent mass values, even under repeated handling and long-term use.

Calibration & Traceability of M1 Class 500g Weight (ISO/IEC 17025)

Each M1 Class Weight of OIML R111 500g is supplied with:

• A standard manufacturing certificate
• A calibration certificate produced in accordance with OIML R 111-1:2004
• Calibration traceability compliant with ISO/IEC 17025:2017

This ensures a documented and uninterrupted traceability chain to recognized mass standards, fulfilling regulatory and accreditation requirements. The certified calibration data allows laboratories and industries to confidently use the weight for routine checks, internal audits, and compliance reporting.

Permissible Error & Tolerance for M1 Class 500g Weight

The 500g M1 calibration weight conforms to the permissible error limits defined under OIML tolerance class M1. These tolerances are suitable for:

• Commercial weighing systems
• Industrial process control
• Routine laboratory balance verification

The controlled magnetic susceptibility (X < 0.8) further enhances measurement reliability by minimizing magnetic influence on electronic balances.

Applications of M1 Class 500g Weight in Industrial & Laboratory Use

The M1 Class 500g weight is widely used across multiple sectors, including:

• Industrial weighing scale verification
• Routine laboratory balance checks
• Quality control and inspection processes
• Manufacturing and process industries
• Educational and testing laboratories

Its robust design and certified accuracy make it an ideal reference weight where repeatability and reliability are essential but ultra-fine tolerances are not required.
