About This Item
ASTM E822 is the ASTM standard for determining the resistance of solar collector covers to hail by impact with propelled ice balls. It provides a practical way to evaluate how cover materials respond to a hail-like impact condition, helping buyers, engineers, and manufacturers compare products with greater confidence. For solar thermal or related collector assemblies, this type of testing supports more consistent product assessment and helps reduce uncertainty when durability against weather exposure is important.
What is ASTM E822?
ASTM E822, titled Standard Practice for Determining Resistance of Solar Collector Covers to Hail by Impact with Propelled Ice Balls, describes a test practice focused on impact resistance. Its purpose is to help assess whether solar collector covers can withstand hail-like strikes under controlled conditions. As an ASTM standard, it is useful for technical evaluation, performance comparison, and quality-related decision-making. The document centers on the cover material or glazing element rather than on the full collector system.
Where is ASTM E822 used?
This standard is commonly used in testing and evaluation settings for solar collector covers, especially where weather durability is part of product qualification or procurement review. It may be applied by manufacturers, laboratories, specifiers, and engineering teams working with solar collector glazing or cover materials. ASTM E822 is also relevant when comparing candidate materials, checking product performance, or supporting documentation for durability-related requirements tied to hail impact resistance.
Why is ASTM E822 important?
ASTM E822 helps create a consistent method for judging how solar collector covers respond to hail-type impact. That consistency matters for compliance reviews, quality control, and product selection because it gives stakeholders a common technical basis for comparison. By using a defined practice, organizations can better evaluate durability claims, support procurement decisions, and reduce the risk of premature damage in service. In short, ASTM E822 supports more reliable performance assessment.
