The Perpendicularity Verification Device (PVD) is an essential tool designed to ensure accurate alignment of concrete cylinders during compressive strength testing with Concrete Compression Machines. Compliance with the latest ASTM C39/C39M standards requires that cylinder alignment be verified to fall within ±0.5° of vertical when using Unbonded Caps for testing. The PVD simplifies this process by offering a practical, user-friendly solution.
How It Works:
The PVD is used after the specimen loading begins but before 10% of the total load is applied. Simply place the PVD on the bottom machine platen and position it against the cylinder. Using the included Gap Measurement Tool, check the gap between the device and the cylinder. If the tool does not pass through the gap, the cylinder alignment is within the required tolerance, and testing can proceed confidently.
Key Features and Benefits:
- Precision Alignment: Ensures cylinder alignment within ±0.5° of vertical, meeting ASTM C39 standards for reliable test results.
- Durable Construction: Made from high-quality, precision-machined aluminum for long-term use in demanding environments.
- Innovative Base Design: The recess cut at the bottom of the device prevents interference from Retaining Rings or spacers during testing.
- Versatile Compatibility: Available for both 4x8in (102x203mm) and 6x12in (152x305mm) concrete cylinders, ensuring broad application across testing setups.
- Lightweight and Easy to Use: The PVD is simple to handle and operate, making alignment verification a quick and hassle-free process.
