It is hard to understand some part of EN1712, please give me a hand :-)
1. Clause 3.4 describes evaluation levels for each methods suggested in clause 3.2, but method 3. What would be the evaluation level for method 3?
2. According to clause 3.5 and figure A.1, the recording levels for method 1 are reference level -2dB or reference level - 6dB. And, the acceptance levels are given by table A.1 and figure A.1. If the indication has peak amplitude of reference level -6dB and length of 1.5T. This indication is not the subject of recording but not-acceptable indication. Is it correct?
3. At 3rd paragraph of clause 4.1, it is stated that any planar indication is not acceptable. Is this statement goes well with the acceptance criteria suggested table A1/A2 and figure A1/A2?
