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.

This standard covers the materials performance of elastomeric turbocharger hoses with three (3) layers.

Four (4) layer hoses for higher service temperatures are specified in GMW15408, four (4) layer hoses with moderate temperature requirements are subject of GMW16144.

Materials covered by this specification are divided into four (4) types.

Type A.

Acrylonitrile Butadiene Rubber (NBR) respectively Polychloroprene (CR) lining, and Polychloroprene cover for +100 °C permanent and +125 °C peak temperatures.

Type B.

Acrylic Ester/Ethylene Copolymer (AEM) in lining and cover for +160 °C permanent, and +175 °C peak temperatures. Can be used for turbo charger systems with Exhaust Gas Recirculation (EGR).

Type C.

Polyacrylate Rubber (ACM) in lining and cover for +175 °C permanent, and +185 °C peak temperatures with occasional extreme peaks at +200 °C. Can be used for turbo charger systems with EGR.

Type D.

Drawing defined (e.g., using SAE J200 or ASTM D2000 line callout).

Type E.

Chlorinated Polyethylene Rubber (CM) in lining and cover for +125 °C permanent, and +135 °C peak temperatures.

Type F.

AEM in lining and cover for +175 °C permanent, and +185 °C peak temperatures. Can be used for turbo charger systems with EGR.

All hoses shall have textile reinforcement suitable to fulfill the requirements of the material and durability tests.

Symbols.

Not applicable.

Applicability.

Hoses in turbo charger circuits.

Remarks.

None.
