Shoulder Fixtures for Pull-Off and Component Testing

Precision Shoulder Grips for Tensile Testing on NG-EML and SHM Series UTMs

NextGen’s shoulder fixtures are specialized tensile grips designed to accommodate specimens with shoulder geometries. These fixtures are critical for standardized testing in accordance with ISO and ASTM protocols where alignment, clamping precision, and repeatability are essential. Compatible with NG-EML and SHM UTMs, these fixtures ensure high-reliability results in both R&D and production environments. 

Typical standards supported include: 

• ASTM D638 (Tensile Properties of Plastics) 
• ISO 527 (Tensile Testing of Plastics) 
• GB/T 1040 (Plastic Tensile Test Methods) 

Applications range across polymer composites, machined plastic components, and metals formed to shoulder profiles. All models support safe and rigid clamping under increasing loads.
