Accelerated Testing: Challenges and Opportunities.



Christopher C. White, Donald L. Hunston


Materials exposed to outdoor weathering will change properties. Currently there are no test methods that result in predictions for those materials. This lack of an ability to predict how the properties will change with weathering results in three problems related to materials selection and use: 1). estimating reserve capacity of existing systems, 2) selection of materials for new applications, and 3) reducing the risk associated with new materials development. Currently, the durability or in-service performance is estimated using two methods: short term accelerated test methods that rely on serial exposure to elevated elements of environmental stress, (higher temperatures, immersion in hot water) or longer term outdoor exposure in locations known to have higher levels of environmental stress than most locations. The advantages and disadvantages of these methods were discussed. A new type of accelerated test method appears possible with the issuing of a new ASTM standard, that of ASTM 1850. This new standard will be incorporated into the ongoing work at NIST on durability research.
