NM01MILSTD271MPCS

The MIL-STD-271F Magnetic Particle Test Plate from PH Tool is a specifically designed reference standard used to verify the effectiveness and sensitivity of the magnetic particle inspection (MPI) process. This test plate is manufactured in accordance with the requirements of MIL-STD-271F (SHIPS), paragraph 4.3.1.2, and also meets the requirements of newer NAVSEA Technical Publication T9074-AS-GIB-010/271, paragraph 4.3.1.2.

This essential tool contains two precisely machined EDM (Electrical Discharge Machining) notches of defined dimensions: 0.020 inches deep x 0.006 inches wide x 0.063 inches long. These artificial flaws are strategically oriented on the plate – one notch is parallel to the intended weld direction, and the other is perpendicular.

To prevent mechanical holding of the magnetic particles and ensure that indications are solely due to magnetic leakage fields, the notches are filled flush with a non-conducting material, typically epoxy.

The test plate itself is constructed from 3/8 inch thick low alloy steel, with overall dimensions of approximately 6 inches wide x 12 inches long.

Key Selling Points:

• Complies with MIL-STD-271F: Ensures adherence to a recognized military standard for MPI process verification.

• Contains Precisely Machined EDM Notches: Provides consistent and repeatable artificial flaws for testing sensitivity.

• Dual Notch Orientation: Allows for evaluation of particle response to flaws in different directions relative to a simulated weld.

• Notches Filled Flush: Prevents mechanical trapping of particles, ensuring accurate assessment of magnetic field leakage.

• High-Quality Low Alloy Steel Construction: Provides a representative test medium for many common applications.

• Manufactured by PH Tool: Backed by the trusted reputation of PH Tool for high-quality NDT reference standards.

Benefits:

• Verifies MPI System Performance: Allows users to confirm the effectiveness of their magnetic particle inspection process.
