E1 Class Weights 50kg – High-Precision Calibration Standards for Laboratory and Industrial Use

Precision is the backbone of modern scientific research, pharmaceutical manufacturing, and metrology labs. For environments where even the smallest deviation can affect outcomes, E1 Class Weights 50kg stand as a benchmark in measurement accuracy. Designed for ultra-high-precision calibration tasks, this 50kg E1 Calibration Weight is ideal for laboratories, calibration service providers, R&D centres, and institutions operating at the highest metrological standards.

What Are E1 Class Weights 50kg?

The E1 Class Weights 50kg are high-accuracy standard weights used to calibrate precision balances and serve as reference standards in mass measurement systems. These weights comply with the OIML R111-1:2004 standard and fall under the E1 tolerance class, which is the most precise classification under the OIML guidelines. Our 50kg E1 Calibration Weight ensures accuracy that meets the strict demands of international laboratories and calibration centres.

Technical Specifications of 50kg E1 Calibration Weight

Understanding the technical configuration is critical when selecting a calibration weight. Our E1 Class Weights 50kg are designed and manufactured to support the highest level of performance and traceability. Here are the key technical details:

• Material: SS-316 Austenitic Stainless Steel (High-grade, Non-magnetic)
• Density: 8000 (±30) kg/m³
• Magnetic Susceptibility (X): Less than 0.02 – ideal for magnetic-sensitive calibration
• OIML Tolerance Class: E1 and E2 compliant
• Capacity: 50 Kilograms
• Surface Finish: Mirror-polished, corrosion-resistant
• Packaging: Supplied in a robust hard-case aluminium box for safe transportation and storage
• Calibration Certificate: Includes manufacturer’s certificate and a calibration certificate issued in compliance with OIML R111-1:2004 and ISO/IEC 17025:2017 standards

Superior Material for Long-Term Stability

The 50kg E1 Calibration Weight is made from SS-316 austenitic stainless steel, known for its high corrosion resistance, excellent non-magnetic properties, and chemical stability. These characteristics ensure the weight remains unaffected by external environmental factors, preserving its integrity over extended periods.

The monobloc design further enhances long-term dimensional stability and eliminates the risk of internal voids or density variation, commonly found in fabricated weights. This makes our E1 Class Weights 50kg exceptionally durable and stable under varying atmospheric conditions.

Why Magnetic Susceptibility Matters

For E1 class calibration weights, low magnetic susceptibility is critical. Our 50kg E1 Calibration Weight maintains a susceptibility of < 0.02, ensuring that it is virtually unaffected by ambient magnetic fields. This feature is essential for labs using magnetic force restoration balances or working in environments where electromagnetic interference can compromise calibration results.

Included Documentation: Calibration You Can Trust

Each E1 Class Weights 50kg unit is delivered with:

• A standard manufacturing certificate, verifying material and dimensional conformity
• A traceable calibration certificate, generated in accordance with OIML R 111-1:2004 and ISO/IEC 17025:2017 standards by an accredited laboratory

This documentation ensures full compliance for audits, traceability requirements, and ISO certification.

Applications of 50kg E1 Calibration Weight

The 50kg E1 Calibration Weight is engineered for sectors and operations that require the highest level of mass accuracy and traceability:

• National Metrology Institutes (NMIs)
• Accredited Calibration Labs (ISO 17025)
• Pharmaceutical R&D Laboratories
• Aerospace and Defence Quality Control
• High-precision analytical balance calibration
• Mass comparator setups
• Reference standards for E2 weight calibration

Whether you're performing internal calibration, third-party auditing, or establishing traceability chains for equipment, these weights are indispensable for meeting industry-specific quality standards.

Designed for Convenience and Safety

To ensure ease of handling and maximum protection, our E1 Class Weights 50kg are supplied in a durable hard-case aluminium box. This packaging solution protects the weight from environmental damage, physical impacts, and contamination. Its design also supports organized storage and transport, minimizing the risk of misplacement or improper handling.

The ergonomic knob-type handle simplifies secure lifting and positioning, even for heavy 50kg units, which is crucial for maintaining clean surfaces and preventing calibration errors due to improper contact.
