moisture absorptionEdit

Originally proposed at Wikidata:Property proposal/Natural science

Descriptionquantity of moisture a material would absorb in given conditions.
Representsbase material (Q214609) > mechanical property of materials (Q5725005) > moisture (Q217651)
Data typeQuantity
Template parameterThis proprety request is part of the project of creating an infobox for materials.
DomainPhysical and mechanical property of some Materials like Nylon.
Allowed valuesAny number. Qualifiers : temperature (P2076) (shall be mandatory), pressure (P2077), determination method (P459).
Allowed units%, ppm
Example 1nylon 6 (Q109454) → 2,7% determination method (P459) → equilibrium at 50% RH, 9,5% determination method (P459) → Saturation in water / temperature (P2076) → 23°C / pressure (P2077) → 1 bar
Example 2nylon 6-6 (Q7071155) → 2,5..3,1% determination method (P459) → equilibrium at 50% RH, 8..9% determination method (P459) → Saturation in water / temperature (P2076) → 23°C / pressure (P2077) → 1 bar

Planned useCreating an infobox for materials

Motivation

This proprety request is part of the project of creating an infobox for materials. The moisture absorbtion is also a necessary qualifier for mechanical propreties of some polymers like Nylon. Exemple of a PA6 datasheet.

Discussion

  •   Comment On some datasheet moisture absorbtion is used as a header for all cases. In others, moisture absorbtion refer to 24H or equilibrium at 50% RH. Water absorbtion is then used for saturation in water. This seems more logical. It could be interesting to have both parameters to display 2 lines on infoboxes. However the risk is that people get confused and use the one instead of the other. -- Thibdx (talk) 12:20, 16 July 2018 (UTC)

  •   Comment I've asked about similar property here. This two properties seems very much alike, so I think we should consider putting some constraints or using specific qualifiers before creating potential duplicate. Wostr (talk) 00:24, 23 July 2018 (UTC)
Proposal is to validate Moisture absorbtion and to close Water absorbtion request. "Water absorbtion" will then be added as an alias to Moisture absorbtion (Pxxx). Moisture absorbing materials are generally not used underwater so that it would generally be searched under this label. Thibdx (talk) 21:02, 26 July 2018 (UTC)
