ASTM International (ASTM) – Provides standardized methods for accelerated aging tests in various materials, including polymers, metals, and coatings. For instance, ASTM F1980 is a standard guide for accelerated aging of sterile barrier systems for medical devices. [22]
Several types of accelerated aging of packaging and materials can be accomplished in a laboratory. Exposure to elevated temperatures accelerates some degradation mechanisms. An Arrhenius equation is often used to correlate certain chemical reactions at different temperatures, based on the proper choice of Q 10 coefficients.
Accelerated photo-ageing of polymers in SEPAP units is the controlled polymer degradation and polymer coating degradation under lab or natural conditions. The prediction of the ageing of plastic materials is a subject that concerns both users and manufacturers.
Under NIJ Standard-0101.07, the velocity used for testing conditioned and unconditioned armor is the same. Armor conditioning procedures are outlined in ASTM E3078 Standard Practice for Conditioning of Hard Armor Test Items. [10] Generally, textile armor material temporarily degrades when wet.
Accelerated life testing is the process of testing a product by subjecting it to conditions (stress, strain, temperatures, voltage, vibration rate, pressure etc.) in excess of its normal service parameters in an effort to uncover faults and potential modes of failure in a short amount of time.
People who consume a lot of ultra-processed foods experience faster rates of biological aging, a recent study has found.

The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
