6、See 8.1. SAE - 2 - AMS 3095A AMS 3095A 1. SCOPE: 1.1 Form: This specification covers a high gloss paint system for use on civil aircraft. 1.2 Application: This product is used typically for contact with external surfaces of civil aircraft, but usage is not limited to such applications. Each applicat
7、ion should be considered separately. This standard may also be used as a basis for special coatings such as anti-erosion, anti-slip, semi-gloss and matte coatings. 1.3 Classification: Specific classes are not defined. The supplier shall define the paint system (see 3.1). Normally it consists of a co
8、mbination or selection of the following types of products: Pretreatment Primers, undercoats and fillers Intermediate coats, such as a selective strippable coat Top coats Clear coats 1.4 Precautions: 1.4.1 Safety - Hazardous Materials: Shall be in accordance with AS5502 (1.1). 2. APPLICABLE DOCUMENTS
9、: The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein.
