Product details

Magnetic particle standard sensitivity test plate type A1 magnetic particle standard test plate

Jane interface:

A1 type specimens sensitivity * first put forward by the Japanese society for nondestructive testing, after use to many countries, it is mainly used for magnetic particle inspection of the parts and components during the inspection, the complex geometric shapes, different materials, can choose magnetization specifications correctly, and can check inspection equipment, the performance of magnetic powder and magnetic suspension, in the process of magnetic particle inspection operation, can prevent undetection, correctly know the peak current needed for detection and direction, and measured with the magnetic field strength shows defect type A specimens sensitivity is magnetic powder flaw detection workers essential debugging tool.

Special point: test piece for magnetic powder display, image intuitive, easy to use. The magnetic field of all kinds of parts in all directions, especially when examining the complex shape of the parts, shows its unique advantages.

Performance specification:

The A-type standard test tablets were divided into A1 and A2. A1 is made of annealed material, and A2 is made of cold-rolled material without heat treatment. This test piece is specially marked A1 test piece according to jb4730-2005 standard, corresponding to Japanese jisg0565-6 standard and American ASME SE709 standard. This coupon is A1 (15/50) standard coupon. It is equivalent to the standard sensitivity indicator 2# (30/100) in type A1 pilot film, and the standard sensitivity indicator is (8-9) D. Suitable for medium sensitivity flaw detection, where the numerator in parentheses is the groove depth, the denominator is the thickness of the specimen, the unit is (micron), and D is the diameter of the workpiece. This test kit includes:

1# 15/100 comforters 2# 30/100 comforters 3# 60/100 comforters 4# 7/50 comforters 5# 15/50 comforters 6# 30/50 comforters are composed of six different sizes

Usage:

1, the standard test piece is suitable for continuous magnetization method, when the use of the appropriate sensitivity of the test piece should be selected, the carved groove side toward the workpiece, closely affixed with adhesive tape, to ensure good contact between the test piece and the surface of the test piece, tape paste on the two edges of the test piece, can not cover the test piece on the back of the groove.

2. The workpiece is magnetized by the method of external suspension, and the test piece is coated with magnetic suspension or magnetic powder (the magnetization specification is gradually improved by the lower level, and the magnetic mark is shown as the boundary, that is, the magnetization current). After the above steps are completed, magnetic marks can be clearly displayed on the test piece affixed to the surface of the workpiece.

Matters needing attention:

Before using the test piece, gently wipe off the oil stains on the test piece surface with soft paper or gauze, and then stick it on the workpiece with adhesive tape to ensure good contact between the test piece and the tested surface.

2. Apply anti-rust oil after use.

3. The test piece shall not be used when it is corroded, folded or changed in magnetic properties.

This test piece conforms to the standard: JB/ t6065-04 ASME SE7709 and other standards.
