EN Pressure Plate Designation Meaning? E.g. P460NL,vs P460NJ2 etc 1

[hkxz]

Dear Sir,

Could anyone enlighten me on the subject of plate designation for EN plates?

I understand from EN 10027-1 the following:
For example: P460NL
-P: Pressure
-460: Mechanical property value
-N: Normalized
-L: Low temperature

However, I could not find what are the meanings of designations such as J2, J4.

Thank you for your help.

CVN values.
J: 27J - K: 40J - L: 60J
R: room temp - 0: 0° celcius - 2: minus 20 °C - 4: minus 40°C

J2: at least 27J @ minus 20°C
Can be found in EN10025 or EN10027, will check this evening.

Get a hold of the material specs youre working with to find out what youre working on.
kingnero is correct.
