Full title and description

St SAE AMS1741-2015 — Compound, Alkaline Degreaser for Aircraft Turbine Engine Components. This Aerospace Material Specification defines requirements for an alkaline degreaser supplied as a liquid concentrate or a water‑soluble powder intended for dilution with water for cleaning aircraft turbine engine components.

Abstract

AMS 1741:2015 specifies the formulation types, performance and compatibility expectations, packaging and marking, and acceptance criteria for alkaline degreaser compounds used on turbine engine hardware. The document is intended to ensure a reproducible cleaning process that removes soils while minimizing corrosion or damage to engine alloys and finishes.

Scope

Defines requirements for an alkaline degreaser compound intended for cleaning aircraft turbine engine components. The specification covers acceptable product forms (liquid concentrate or water‑soluble powder), dilution for use, performance expectations (cleaning effectiveness and material compatibility), packaging, marking and associated test or acceptance procedures. It is aimed at ensuring degreasing agents are effective at soil removal while being safe for typical engine alloys and finishes when used per the specification.

Key topics and requirements

• Approved product forms: liquid concentrate and water‑soluble powder for dilution with water.
• Performance and acceptance criteria for cleaning efficiency on typical engine soils.
• Material compatibility guidance to avoid corrosion or damage to titanium, nickel and cobalt alloys commonly found in turbine engines.
• Packaging, labeling and storage requirements suitable for aerospace maintenance, repair and overhaul (MRO) environments.
• Test references and cross‑referenced standards or methods used for verification (see related standards list).

Typical use and users

Used by aircraft OEMs, airline maintenance and overhaul organizations (MROs), engine shops, military depots and chemical suppliers that formulate or supply approved cleaning compounds for turbine engine maintenance. The standard guides procurement, acceptance and use of alkaline degreasers in aerospace engine cleaning operations.

Related standards

AMS 1741 references and is commonly considered alongside other cleaning and material compatibility documents (examples of cross‑references reported for the AMS 1741 record include ARP 1755 and relevant ASTM cleaning/test methods such as ASTM D1568, ASTM D2667 and ASTM F945). Users should consult the AMS 1741 text for the exact normative references and any referenced test methods.
