Full title and description
ASTM E650/E650M-24 — Standard Guide for Mounting Piezoelectric Acoustic Emission Sensors. This guide provides recommended practices, mounting fixtures, couplants/bonding agents, and procedures intended to produce repeatable and optimum detection of piezoelectric acoustic emission (AE) transducers used in AE testing and monitoring programs.
Abstract
This guide covers guidelines for mounting piezoelectric acoustic emission sensors, including choice and preparation of mounting surfaces, selection and application of couplants or bonding agents, use of mounting fixtures and waveguides, and considerations for units (SI and inch–pound). It emphasizes reproducible mounting procedures to maintain sensor performance and detection sensitivity.

Scope
The standard provides practical, nonmandatory guidance on mounting piezoelectric AE sensors to test articles and structures. It addresses surface preparation, types of couplants and adhesives, mechanical mounting fixtures and waveguides, recommended mounting torque and contact methods, and considerations when switching between SI and inch–pound units. Safety, environmental, and application-specific limitations are noted as the user’s responsibility.
Key topics and requirements
- Guidelines for sensor placement and orientation to optimize AE detection.
- Surface preparation and cleaning procedures for reliable acoustic contact.
- Selection and application of couplants, bonding agents, and adhesives.
- Use of mechanical mounting fixtures, studs, and waveguides where appropriate.
- Requirements and notes on unit systems (SI and inch–pound are independent).
- Recommendations for reproducible mounting procedures to ensure consistent sensitivity.
- Notes on safety and environmental considerations for mounting operations.
Typical use and users
Used by acoustic emission engineers, NDT/inspection technicians, test laboratories, researchers, and manufacturers deploying piezoelectric AE sensors in structural monitoring, materials testing, pressure vessel and pipeline inspection, and laboratory experiments. The guide is referenced when establishing sensor-mounting procedures, purchase specifications for fixtures/waveguides, and training materials for AE technicians.
