| stability | |||
| Constancy of a property of a material over time. | |||
| Note 1: | A material is said to be stable with respect to a specified property if its measured or examined property values do not fall outside a specified interval during storage under specified conditions over a specified period of time. | ||
| Note 2: | A reference material is assessed for the stability of an embodied property under conditions of transport (“short-term stability”) and storage (“long-term stability”). | ||
| See: ref. 3 Section 2.1. | |||
| Note 3: | The variation of the property value over time adds a contribution to the uncertainty budget or the examination uncertainty, as applicable. Regarding the assessment of stability of reference material, detailed guidance is given in ISO Guide 35.24 | ||
| Note 4: | The term “stability” is also used for stability of a measuring instrument or process (see control limit). | ||
