Carpet Thickness Gauge

The Carpet Thickness Gauge is designed to accurately measure the thickness of carpets and textile floor coverings under a standardized pressure. By applying a defined load to a specimen, it ensures consistent and repeatable measurements, accounting for the compressible nature of carpet materials. This instrument is essential for quality control, material specification, R&D, and compliance with international standards.

Application

(1) Measuring total thickness of carpets and other resilient floor coverings under standard load.

(2) Determining pile height by measuring total thickness and backing thickness separately.

(3) Quality control during carpet production to ensure product consistency.

(4) Material specification and comparison for carpet construction evaluation.

(5) Research and development of new carpet designs, fiber blends, and hybrid materials.

(6) Evaluating tufted, woven, needle-punched, and nonwoven carpets.

(7) Assessing textile mats, rugs, underlays, and artificial turf.

(8) Testing multilayer flooring composites and laminated textile materials.

(9) Ensuring compliance with performance criteria for commercial, residential, automotive, and industrial carpet applications.

Standards

(1) ASTM D418 – Standard Test Methods for Thickness of Pile Carpets and Rugs.

(2) ISO 1765 – Textile floor coverings — Determination of thickness.

(3) ISO 5084 – Determination of thickness of textiles.

(4) BS 4051 – Methods for the determination of carpet thickness.

(5) EN 1307 – Textile floor coverings — Classification, specification, and test methods.

(6) JIS L 1904 – Method for measurement of pile height and thickness of carpets.

Features

(1) Flat, stable base plate to support the carpet specimen.

(2) Presser foot with a precisely defined area and diameter for standardized measurement.

(3) Mechanism for applying a controlled downward pressure using calibrated weights or springs.

(4) Displacement measuring device (dial gauge, digital indicator, or linear encoder) for precise thickness readings.

(5) Smooth and gentle presser-foot lowering mechanism to avoid impact effects.

(6) Digital or analog display with zero-setting and hold functions.

(7) Durable construction suitable for laboratory or production use.

Parameters

Accessories

(1) Optional extended anvil kit for thicker carpets.

(2) Calibration weights or springs for presser-foot adjustment.

(3) Carrying/storage case.

(4) User manual and calibration certificate.

Test Procedures

(1) Place the carpet specimen flat on the base plate.

(2) Lower the presser foot gently onto the sample.

(3) Apply the standardized force using the weight or spring mechanism.

(4) Read the displacement from the dial gauge or digital indicator.

(5) For pile height determination, measure backing thickness separately and calculate the pile height.

(6) Record results and repeat for multiple points to ensure uniformity.

Maintenance Information

(1) Keep the base plate and presser foot clean and free of debris.

(2) Periodically check calibration using reference standards.

(3) Avoid exposure to high humidity or corrosive environments.

(4) Replace batteries as needed for digital units.

(5) Store in a protective case when not in use.
