DES Labs performs a wide range of mechanical tests on metals, weldments, pipes, and tubes to ensure material integrity
and adherence to global industry standards. Operating from our ISO/IEC 17025:2017 accredited laboratory in Gulbarga,
Karnataka (NABL Certificate Number: TC-9999), we utilize advanced equipment to deliver precise, reliable results. Below
is a detailed overview of our mechanical testing services and state-of-the-art equipment.

Mechanical Testing Services

Tensile Testing

Our tensile testing evaluates material strength, ductility, and other critical properties under tension, ensuring
compliance with standards such as:

• ASTM A370, ASTM E8/E8M, ASTM E21
• IS 1608
• ISO 6892

Capabilities:

• Testing at room temperature and elevated temperatures up to 900°C.
• Determination of Young’s modulus, proof stress (0.01% to 1%), and ultimate tensile strength.
• Suitable for metals, weldments, torsion steel, and other components.

Hardness Testing

We conduct hardness tests to assess material resistance to indentation, adhering to standards including:

• ASTM A370, ASTM E10, ASTM E18, ASTM E92, ASTM E384
• IS 1500, IS 1501, IS 1586
• ISO 6506-1, ISO 6507-1, ISO 6508-1, ASTM A956

Capabilities:

• Brinell hardness (187.5/2.5 to 10/3000 loads).
• Rockwell hardness (A, B, C scales, including superficial N and T scales).
• Vickers hardness (30 kg to microhardness at 10 grams).
• Case depth analysis and portable on-site hardness testing.

Additional Mechanical Tests

• Impact Testing: Charpy and Izod tests to measure toughness, per ASTM E23 and ISO 148.
• Bend and Rebend Testing: Verifies flexibility and weld integrity, compliant with ASTM A370 and
  IS 1599.
• Flattening, Flaring, and Drift Expansion Testing: Ensures formability of pipes and tubes, per
  ASTM A370 and IS 2328.
• Fracture and Fatigue Testing: Assesses material behavior under cyclic loading, per ASTM E647.
• Micro Hardness Testing: Localized hardness analysis for weldments, per ASTM E384.
• Hardenability Testing: Evaluates heat-treated material hardness depth, per ASTM A255.
• Erichsen Cupping Testing: Tests sheet metal formability, per IS 1075.
• Weldment Testing: Includes weld and electrode qualification, minimum leak path, and nodularity
  count, per ASME Section IX and AWS standards.

Advanced Testing Equipment

• Universal Testing Machines (UTM): Capacities of 1 kN, 5 kN, 50 kN, 100 kN, 300 kN, 400 kN, and
  1000 kN, equipped with digital load indicators and extensometers for precise tensile, compression, and bend
  tests.
• Hardness Testers: Automated Rockwell, Vickers, and Brinell testers with calibration for
  accurate measurements across all scales.
• Impact Testing Machines: Automated Charpy and Izod testers with sub-zero electronic bath for
  low-temperature testing.
• Micro Hardness Testers: High-precision systems for micro-scale hardness analysis.
• Fatigue Testing Systems: Servo-hydraulic machines for cyclic loading and fracture toughness
  testing.
• Erichsen Cupping Testers: Specialized equipment for assessing sheet metal formability.
• In-House Specimen Preparation: CNC machining and sample preparation facilities to ensure
  accurate, client-specific test specimens.
