SCOPE: 1.1
5、 Form: This specification covers an anti-galling compound remover in the form of a water-soluble powder, a concentrated liquid for dilution with water, or a ready-to-use liquid. 1.2 Application: This remover has been used typically for removal of anti-galling compounds from turbine engine components
6、 by immersion at room temperature in a solution of the remover or ready-to-use liquid, but usage is not limited to such applications. This remover shall not be used on steel parts having hardness of 40 HRC or over. 1.3 Classification: Remover conforming to this specification is classified as follows
7、: Type 1 - Water-soluble powder Type 2 - Liquid concentrate Type 3 - Ready-to-use liquid 1.3.1 Type 1 shall be supplied unless Type 2 or Type 3 is ordered. 1.4 Safety - Hazardous Materials: While the materials, methods, applications, and processes described or referenced in this specification may in
8、volve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the
9、health and safety of all personnel involved. AMS 1387A SAE AMS 1387A - 2 - 1.5 Precautions: Remover may contain chemicals which, if improperly used, could be hazardous to the health and safety of operators. Protective clothing including eye shields, suitable gloves, and apron should be worn when pre
10、paring and using remover. Tanks shall be prepared and operated under conditions of adequate fume extraction and with due regard to the safety recommendations of the manufacturer of the remover together with local workshop safety regulations. 2.
