Perpendicular Verification Device For Concrete Cylinder, 6in

Perpendicular Verification Device For Concrete Cylinder, 6in

The PVD (Perpendicular Verification Device) sits on the bottom machine platen of your testing machine and provides a quick, easy and accurate verification of cylinder perpendicularity to meet ASTM C39.

Each Perpendicular Verification Device is designed to reach the test specimen without contacting your ASTM compliant top and bottom retaining cups.

A Gap Measurement Tool (PVD-TOOL) is also included. Use as a “go”/ “no-go” check.

Product Description

The Perpendicularity Verification Device (PVD) is a precision tool to verify the accurate alignment of concrete cylinders during compressive strength testing. This is a must-have accessory for compression machines to get accurate and reliable test results. The PVD meets the standards of ASTM C39 and C39M and provides a quick and accurate verification of cylinder perpendicularity. By using this verification device in your testing process, you can ensure your concrete cylinders are properly aligned, which is key to getting valid and consistent test results.

Key Features and Specifications: Sturdy Machined Aluminum Construction

• Sits on lower platen of compression machine: Stable and accurate positioning.

• Verifies cylinder perpendicularity: Meets ASTM C39 and C39M.

• Multiple sizes available: 2″ x 4″, 3″ x 6″, 4″ x 8″, 6″ x 12″ to fit various testing needs.

• Reaches test specimen without contacting retaining rings: Doesn’t interfere with top and bottom retaining rings.

• PVD-TOOL included: “go”/“no-go” check for perpendicularity.

• Machined aluminum construction: Durable and reliable.

• Manually positioned against cylinder: After loading has started but before 10% of total load is reached, to get accurate alignment.

• Works with concrete compression machines and retaining cups: More versatile and user friendly.

Installation and Setup Instructions

1. Mounting the Perpendicular Verification Device (PVD): Begin by placing the PVD on the lower platen of your compression machine. Ensure that the device is securely positioned and level to provide a stable base for accurate verification.

2. Positioning the PVD: Manually position the PVD against the test specimen (cylinder) after the loading process has started but before reaching 10% of the total load. This ensures that the cylinder is properly aligned for accurate testing.

3. Gap Measurement Tool: Utilize the included Gap Measurement Tool to check the gap between the PVD and the cylinder. This tool acts as a “go”/“no-go” check, ensuring that the cylinder is perpendicular and meets the required standards.

4. Avoiding Contact: Make sure that the PVD reaches the test specimen without making contact with the top and bottom retaining cups or rings. This prevents any interference that could affect the accuracy of the verification.

5. Square Spacer: If you are using a square spacer, ensure it is correctly aligned and positioned to maintain the squareness of the test specimen. This helps in achieving precise perpendicularity.

6. Bottom Retaining Cups: Verify that the bottom retaining cups are securely holding the test specimen in place. This stability is crucial for accurate and reliable test results.

7. Demonstrate Compliance: Use the PVD to demonstrate compliance with ASTM C39 and C39M standards. The device ensures accurate verification of cylinder perpendicularity within ±0.5° of vertical, meeting industry requirements.

8. Sturdy Machined Aluminum Construction: The PVD is constructed with sturdy machined aluminum, providing durability and reliability during testing. This robust construction ensures the device can withstand the rigors of regular use.

9. Concrete Cylinders: The PVD is specifically designed for use with concrete cylinders, ensuring accurate verification of perpendicularity during compressive strength testing. This is essential for obtaining valid and consistent test results.

10. Compression Machine: The PVD is compatible with various compression machines, ensuring seamless integration into your testing setup. This compatibility enhances the versatility and usability of the device.

By following these installation and setup instructions, you can ensure that your Perpendicular Verification Device is properly positioned and functioning correctly, leading to more accurate and reliable test results.
