Introduction

Pressure-sensitive tapes are widely used in industries such as packaging, automotive, electronics, and construction. 

Accurate measurement of tape thickness is critical for ensuring performance, adhesion, and durability. ASTM D3652 

is the recognized standard for determining the thickness of pressure-sensitive tapes, providing a reliable method for

 quality control and compliance.

Scope of ASTM D3652

ASTM D3652 specifies the procedure for measuring the thickness of pressure-sensitive tapes using a micrometer under

 controlled conditions. This method applies to single-layer tapes, laminates, and coated materials, ensuring consistency

 across different product types.

Testing instrument：PTT-03 Thickness Tester

Test Procedure Overview

Sample Preparation – Cut representative tape samples free from wrinkles or deformities.

Micrometer Calibration – Use a calibrated micrometer with a flat anvil and spindle (minimum 6.35 mm diameter).

Measurement – Place the sample between the micrometer’s anvils and apply a controlled pressure (20 ± 3 kPa). 

Record multiple readings at different points.

Calculation – Average the measurements to determine the tape’s thickness, typically reported in mils (0.001 inch) 

or micrometers (µm).

Why ASTM D3652 Compliance Matters

Ensures product consistency and performance.

Facilitates compliance with industry and customer specifications.

Supports quality assurance in manufacturing and R&D.

Conclusion

ASTM D3652 provides a standardized approach to measuring pressure-sensitive tape thickness, essential for

 manufacturers and end-users. By adhering to this method, companies can ensure product reliability and meet

 industry standards.
