Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. [1] In other words, it might refer to whether a ...
In chemistry, chemical stability is the thermodynamic stability of a chemical system, in particular a chemical compound or a polymer. [1]Chemical stability may also refer to the shelf-life of a particular chemical compound; that is the duration of time before it begins to degrade in response to environmental factors.
"Display until" and "use by" expiration dates on a meat product in the United Kingdom. An expiration date or expiry date is a previously determined date after which something should no longer be used, either by operation of law or by exceeding the anticipated shelf life for perishable goods.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Accelerating methods for shelf life prediction [ edit ] The kinetic process of destabilisation can be rather long (up to several months or even years for some products) and it is often required for the formulator to use further accelerating methods in order to reach reasonable development time for new product design.
The maximum shelf life of nitroglycerin-based dynamite is recommended as one year from the date of manufacture under good storage conditions. [ 7 ] Over time, regardless of the sorbent used, sticks of dynamite will "weep" or "sweat" nitroglycerin, which can then pool in the bottom of the box or storage area.

Service life of several thousand hours (continuous operation) [9] Shelf stable over several years (retaining 90% of initial capacity) [10] Silver oxide cells are a primary battery and do not have a cycle life or a rate of charging and discharging. [2] Typical silver oxide cells are stable at temperatures below 100°C, at which point leakage can ...
