Selecting the Test Procedure
There are a variety of water spray test standards between ASTM and AAMA, with other countries sometimes having their own standards. However, many countries around the world have chosen to comply with ASTM standards. This is why ASTM has changed its name to "ASTM International", as to not limit themselves to being only American, which is what the "A" originally stood for in the acronym.
How do you choose which standard to adhere to? It depends on the test specimen you're testing.
- A storefront type window with no moving parts
- Operable, residential type windows, or skylights or doors
The more universally recognized, original standards are the ASTM standards. How do you choose between the ASTM E1105, E331, and E547? There are specific reasons for each although they are performed very similarly to each other. They each require the same type of equipment. Our products are the Rain Maker and Wind Maker, and you save $500.00 when you buy them together.
The E331 is to be performed using only the uniform static air method, the E547 using only the cyclic static air method, and the E1105 can be ran using either static or cyclic air methods. The E1105 is the only one of the three to include methods for testing operable windows. Both the E331 and E547 include instructions for skylight windows whereas the E1105 does not.
Choosing between these ASTM test standards can be complicated. But it is important to know how to choose. Our training program goes in depth on this subject along with other important considerations that need to be made before any water is sprayed or equipment set up.
