What confidence level D means
The two standards fall in the same ICS category but address different subjects. Not an equivalence.
How to use this
A cross-reference tells you where to look, not what the answer is. If the level is A or B, ask your supplier for a test report against the ASEAN standard and compare the measured values with the limits in that standard. If the level is C or D, treat the two documents as separate requirements and check each clause. If the level is E, the product may be regulated under a different instrument in the destination country — for example a food-contact or electrical-safety regulation rather than a product standard — and you should confirm with the importing authority.
