Perpendicularity Verification Device for 4 x 8in Cylinders

The Perpendicularity Verification Device (PVD) is an innovative tool designed to ensure proper alignment of concrete cylinders during compressive strength testing with Concrete Compression Machines. This device helps users meet the latest ASTM C39/39M standards, which now require alignment verification within ±0.5° of vertical for every specimen tested when using Unbonded Caps.

How it Works: Once specimen loading begins and before reaching 10% of the total load, the PVD is placed on the bottom platen of the compression machine and carefully positioned against the concrete cylinder. Using the included Gap Measurement Tool, users can easily check the alignment. If the Gap Tool cannot pass through the space between the device and the cylinder, the specimen is properly aligned, and testing can proceed without interruption. This simple process ensures compliance with ASTM standards and enhances testing accuracy.

PVD Features:

• Precision-Machined Construction: Crafted from durable, lightweight aluminum for long-lasting performance and ease of use.
• Notched Base Design: Designed with a recessed cut at the bottom to prevent interference from Retaining Rings or spacers commonly used during testing.
• Multiple Cylinder Sizes: Available in unique designs for 4x8in (102x203mm) and 6x12in (152x305mm) cylinders to meet diverse testing needs.
• ASTM Compliance: Helps maintain compliance with the updated ASTM C39/39M requirements for alignment verification.

Why Choose the PVD? The Perpendicularity Verification Device simplifies the alignment verification process, saving time and ensuring reliable results in concrete compressive strength testing. Its user-friendly design and precision engineering make it an essential tool for laboratories and technicians focused on maintaining high testing standards.
