Magnaflux test pieces contain precisely defined artificial flaws used to verify that MPI equipment and processes are operating at accepted levels.
| Magnaflux Product | Description | Part Number |
|---|---|---|
| Magnetic Particle Test Bar | Contains coarse and fine surface and subsurface defects in both directions. Meets or exceeds most industrial and military standards for artificial test specimens. | 189838 |
| Tool Steel Test Ring | Test piece with pre-drilled holes to simulate subsurface discontinuities. Meets ASTM E1444 requirements. | D03008 |
| BHEL Test Block | BHEL Test Block is used for Prod Type Inspection.To find out sub-surface defects with prod and coil methods. Meets BHEL requirements. | F05106 |
| MTU Block K-204 | Each MTU block has a unique pattern of crack indications on both sides, of sizes 0.1 - 1.0 μm. | F05098 |
| Continuous Method Test Block | Use this test block to check for proper magnetising of test bench units. Crack indications will form on the block when current flow and bath concentrations are at adequate levels. | 75130 |
| Magnetic Flux Indicators | These strips help to determine the direction of magnetic fields at the precise point of their location. They comply with EN-ISO 9934-1:2001. | F05095 (Type G) |
| Reference Block Type 2 | Use to evaluate the sensitivity of your magnetic ink. Tested in accordance with EN ISO 9934-2. Supplied with certificate and reference picture. | F05081 |
Quantitative Quality Indicators (QQI) Test pieces with artificial defects used to verify field direction and relative strength. QQIs are also used to balance multi-directional fields and to increase productivity by minimising magnetising shots.
| QQI model | Description | Flaw depth | Self-adhesive | Part number |
|---|---|---|---|---|
| Standard, KSC-230 | Basic circular and crossed bar flaw configuration suitable for longitudinal and circular fields. | 30% of Shim thickness, .002” thick (0.05 mm) | Yes | 519630 |
| Standard, KSC-430 | Basic circular and crossed bar flaw configuration suitable for longitudinal and circular fields. | 30% of Shim thickness, .004” thick (0.1 mm) | No | 521048 |
| Miniature, KSC-4-230 | Similar to KSC230, except miniature design for small areas on test part. The four circles may be cut apart for individual use. | 30% of Shim thickness, .002” thick (0.05 mm) | No | 519631 |
| Variable Depth, KSCT-234 | Used for more quantitative work, three concentric circular flaws of differing depth. | 20%/30%/40% of Shim thickness, .002” thick (0.05 mm) | Yes | 519632 |
| Variable Depth, KSC4-234 | Used for more quantitative work, three concentric circular flaws of differing depth. | 20%/30%/40% of Shim thickness, .004” thick (0.1 mm) | No | 521049 |
