Sampling plan for magnetic properties or dimensional attributes is performed according to the customer's specific requests. Otherwise we use MIL Standard 105D Sampling plan for normal inspection.

Magnetization and Magnetic Test Equipment:

Modes of magnetization :

Test Equipment:

* The magnetic properties of test samples are determined using a modern BH tracer potting a full loop demagnetization curve.
* High accuracy calibrated Gaussmeters, Fluxmeters, and some other necessary measuring tools are used for appropriated parts.

Physical and Magnetic Tolerance:

In the absence of clear instruction on magnetic and physical tolerances, we use Magnetic Material Producers Association (MMPA) Standard Specification for Permanent Magnet Material as a guideline.

Required Information for Quotation:

1. Intend application and Material.
2. Shape, size dimensions and tolerance level.
3. Material Characteristic (i.e. Br, bHc, iHc, BHmax¡K)
4. Environmental conditions and Inspection sampling plan.
5. Magnetized or unmagnetized.
6. Magnetic Polarity and magnetized direction.
7. Quantity per year and per shipment..
8. Special request method for packing.
