EN 10160

Could anybody please explain me What product class S0,s1,S2..in standard EN 10160 is? How to classify? And Please guide me how to make the grid scanning on plate (100mm square, 200mm square).It would be good if you have a picture to describe.

A grid scan on flat plate.
Start by placing the probe at one top corner of the plate a few centimeters from the edge, now run the probe down the long side of the plate, scanning until you reach the bottom edge. Move the probe 200mm (if a 200mm grid is required) inboard and follow a scan line parallel to the first line back up to the top edge of the plate. Repeat until you reach the opposite side edge.
Now you carry out the same process along the short side of the plate.
When you have finished a plate, look at it from above and you will see.... a grid!

Hi Waien,
1) plates in the quality of S0, S1 ... The manufacturer may supply proof certificate.
2) control, the external inspector NDT.
The grid 100x100 or 200x200 is an imaginary grid (line) on the plate, after which the probe lead. Event capture defects are examined outside the grid.
As stated by Mr. J. Wallis.

John,
The width of the lines is equal to probe's diameter which is contacted to the plate?

I think you are describing a 100% scan where the scan lines have to overlap which is used on edges, for example. A grid scan is as I previously mentioned. The grid can be any size the norm or specification (or client) requires. Imagine testing a rolled plate, 12m say, fresh from the mill with 100% examination.
It would murder your knees!

Hi gentlemen,
here in the Czech Republic we use for testing long sheets "hockey stick", by Jaroslav Jager (ha ha).
The probe is mounted in a block with a water-binding, using the handle and is guided over the surface.
Testing is walk around the plate.

Hi everyone,

in fact, the product class defines the maximum size of reflectors you have to register and what size of grid width you have to use. The grid starts at the center of the stamp, I think grid width is 200 mm square up to product class S2. Additionaly, S is the product class for the center of the plate, the edges are not tested! Therefore are Product classes E0 - E4. The exact size of defects to be registered depends on the thickness of your plate. I would suggest you read EN 10160, it is quite simple.

Regards
