ASD-STAN/D 3/WG 6 - Coatings for fasteners

This document specifies the application method and quality assurance for aluminium pigmented coatings as per EN 4473 which may be applied to fasteners or other parts in titanium, titanium alloys, nickel or cobalt based alloys and corrosion resisting steels.

This document specifies the performance requirements for aluminium pigmented organic coatings to be applied on titanium, titanium alloys, nickel or cobalt based alloys and corrosion resistant steels.
This specification does not cover electrical bonding and lightning strike applications of these coatings. Additional qualification tests will be agreed with the OEM upon qualification.
NOTE   These coatings are not recommended for use on non-corrosion resistant steel fasteners.

This standard specifies the qualification and test requirements for graphite and halogen free molybdenum disulphide dry film lubricant.
Test requirements and testing of fretting, corrosion, wear and friction properties of relevant lubricants are not part of this standard. Refer to relevant standards in normative references.
All testing defined in this standard has to be certified by the manufacturer of the lubricant.
In order to achieve uniform coatings with defined thickness and best adhesion properties, spray application in combination with heat curing is recommended.

This European Standard defines the coating methods and characteristics of molybdenum disulphide dry film lubricants which may be applied to parts in titanium, titanium alloys, steel, corrosion resistant steel and nickel based alloys.

This document specifies the characteristics and the tests required to qualify and control lots of high purity (≥ 99 %) aluminium coatings applied by ion-vapor deposition (IVD) on fasteners.

This European Standard defines the coating methods and characteristics of aluminium pigmented coatings to EN 4473 which may be applied to fasteners in titanium, titanium alloys, heat resisting nickel base or cobalt base alloys and corrosion resisting steels.

This European Standard defines the qualification test conditions for aluminium pigmented coatings applicable to fasteners in titanium, titanium alloys, nickel base alloys and corrosion resisting steels. The aluminium pigmented coatings are not applicable to fasteners in non-corrosion resistant steels.
Temperature class: 315 °C  
Type I   : Coating with chromate and a cetyl alcohol lubricant.
Type II   : Coating without chromate and an cetyl alcohol lubricant.
Type III   : Coating with chromate, no additional lubricant.
Type IV   : Coating without chromate, no additional lubricant.
