| 2 | P-Draft Waived | 08-11-2023 | Recommendation received from MTD 9 member secretary vide email dt. 23 March 2023 to adopt ISO 3750:2006 Zinc alloys — Determination of magnesium content — Flame atomic absorption spectrometric method as ISO 3750 is more relevant and the latest practise is mentioned. Same was discussed and deliberated during the MTD 34 meeting held on 07.06.2023. The committee decided to adopt ISO 3750:2006 | ------- | |
