Shelf Life

Definition

Shelf life is the maximum interval during which a material may be stored and remain in a usable condition.

Purpose

The purpose of knowing the shelf life of a material is to ensure that it is used within its optimal period of effectiveness, maintaining its quality and functionality.

Examples of Use

• In construction, adhesives and sealants have a specific shelf life to ensure their bonding properties are effective.
• Paints and coatings must be used within their shelf life to ensure proper application and durability.
• Food products in canteens or construction site kitchens are monitored for shelf life to ensure safety and quality.

Related Terms

• Expiry Date: The date after which a material is no longer considered effective or safe to use.
• Stability: The ability of a material to maintain its properties over time.
• Storage Conditions: The environmental factors such as temperature and humidity that affect the shelf life of materials.

Notes

Proper storage conditions can extend the shelf life of materials, while poor conditions can shorten it. Always check and adhere to the manufacturer’s guidelines.
