3. REQUIREMENTS
3.1 Product specification or engineering drawings. The individual item requirements shall be as specified herein and in accordance with the applicable product specification or engineering drawing. In the event of a conflict between the requirements of this specification and the product specification or engineering drawing, the latter shall govern.
3.2 First article inspection. When specified (see 6.3), a sample shall be subjected to first article inspection in accordance with 4.5.
3.3 Materials. The materials shall be as specified herein. When a definite material is not specified, a suitable material shall be used which will enable the solenoids to meet the performance requirements of this specification. Acceptance or approval of any constituent material shall not be construed as a guaranty of acceptance of the finished product.
3.3.1 Fungus resistant materials. Nonmetallic parts of the solenoid shall be inherently nonfungus nutrient or treated to resist fungus growth.
3.3.2 Metals. Metals shall be of a corrosion resistant type, or shall be plated or treated to resist corrosion.
3.3.2.1 Dissimilar metals. When dissimilar metals are used in intimate contact with each other, protection against electrolysis and corrosion shall be provided. The use of dissimilar metals in contact, which tend toward active electrolytic corrosion (particularly brass, copper, or steel used in contact with aluminum or aluminum alloy), is not acceptable. However, metal plating or metal spraying of dissimilar base metals to provide suitable abutting surfaces is permitted. Dissimilar metals should be as defined in 6.5.
3.3.3 Plastic. Plastic material shall be of a type that will enable the solenoid to meet all the performance requirements of this specification.
