Data comes from public supplier literature (cited on each grade page). A blank cell means not stated in the source, not "no". Always confirm with the supplier's current documentation before use.
Property rows are flagged when grades use different test standards or units, because those values are not directly comparable. Values are shown exactly as the data sheet states them; MedResin does not convert units. "Not stated" means the source does not state it, not "no".
