Magnetic Particle Test Pieces

Maintain your process by verifying mag particle performance

These test pieces for magnetic particle inspection will help you maintain your mag particle process by verifying magnetic particle performance. Use to check for mag particle deterioration, to compare different magnetic powders, to verify sensitivity or visibility or to assure field direction and strength.

Quantitative Quality Indicators (QQI)

QQI test pieces are used to verify field direction and relative strength. They also balance multi-directional fields and increase productivity by minimising magnetising shots. QQI test pieces are manufactured strictly in accordance with AISI 1005 - the applicable AMS standard for mild low-carbon steel, which is governed by SAE Aerospace Standard AS 5371. They also conform to ASTM E1444-05 and ASME Boiler & Pressure Vessel Code, Section V, Article 7-764.1.2.

Sold in sets of 5.
