ISO13588 the difference between table A.1 and table A.3

hi, could anyone knows the difference between table A.1 and table A.3, both of them stipulate the length of notch, which one is right? if the thickness of test block is 80mm, what is the length of the notch, 50mm or 40mm?
in my opinion, table A.3 make a mistake, the length of the notch should not be added in table A.3.
could you have any different opinion? thanks

To understand this, please look at ISO 10863:2011-12.
They forgot to copy & paste "bottom of the" in Table A.1.

Table A.1 is for one notch at the bottom of the block.
Table A.3 is for three side-drilled holes located at t/4, t/2 and 3t/4 below the surface, with a diameter Dd (see Table A.2) and a length l (Table A.3). Alternatively three notches at the scanning-surface with depths of t/4, t/2 and 3t/4, a tip angle of 60° (see Figure A.5), a width w (Table A.2) and a minimum length of 40 mm may be used.

So for a 80 mm block you need at least one notch:
Notch-bottom, l=50 mm, h= 2 mm.

This is totally not confusing. And good luck with the 0,2 width and 60° tip angle of the notches!

thanks very much! most of your answer I couldn't agree with more, except that " Alternatively three notches at the scanning-surface with depths of t/4, t/2 and 3t/4, a tip angle of 60° (see Figure A.5)". according to your opinion, the three notch are surface opening artficial reflector? I think it is just a rectangle reflector which is under the scanning surface 1T/4, 2T/4, 3T/4, not a surface breaking notch and with a tip angle of 60°, and the height、width is based on table A.1
looking forward your opinion. thanks again

Hi, that was not my opinion, I took the text straight out of the standard.

To see if they are top or bottom, check out the drawing

Lang, I would point out that Annex A in ISO 13588 is "Informative", not "Normative".
You will read throughout this Annex that the reference reflectors are "recommended".

Dear colleagues,

I want to inform, that a revised edition of ISO 13588 has just been published:

ISO 13588:2019-02,
Non-destructive testing of welds - Ultrasonic testing - Use of automated phased array technology.

Annex A of ISO 13588 is still informative:
Annex A
(informative)
Typical reference blocks and reference reflectors.

With best regards
Udo Schlengermann
