Details
This specification covers the materials and performance of elastomeric hose elbows for duct air cleaner.
Note: Nothing in this standard supercedes applicable laws and regulations.
Note: In the event of conflict between the English and domestic language, the English language shall take precedence.
Purpose/Material Description.
Materials covered by this specification are divided into five (5) types.
Type A. Nitrile Acrylonitrile Butadiene Rubber Copolymer (NBR) for +100 °C permanent and +125 °C peak temperatures.
Type B. Ethyl Acrylate Ethylene Copolymer (AEM) for +160 °C permanent and +175 °C peak temperatures.
Type C. Drawing defined (e.g., using SAE J200 or ASTM D2000 line callout).
Type D. AEM for +175 °C permanent and +185 °C peak temperatures.
Type E. AEM with increased dynamic duct properties for Type B and Type D elastomers.
• Type E is a different dynamic hose spec and requires special testing. (reference Table 2) and Finite Element Modelling (reference 3.4) on the specification.
Symbols.
Not applicable.
Applicability.
Elastomeric hose elbows for duct air cleaner.
Remarks.
All GMW14720 AEM types shall have a Minimum of 50% Base Polymer.
