SAE AMS 2644H:2020 pdf free.Inspection Material, Penetrant
This specification is applicable to penetrant materials used in manufacturing and maintenance operations. It is intended to be used by prime contractors in establishing an approved products list (QPL) for use by themselves and their suppliers. It does not cover such special application products as liquid oxygen compatible, high or low temperatures, thixotropic, reverse fluorescent, and dye precipitation penetrant systems.
While the materials, methods, applications, and processes described or referenced in this specification may involve 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 health and safety of all personnel involved.
Candidate materials and systems must equal or exceed the performance of the appropriate reference material or system.Tables 1 and 2 list the designations assigned to the reference materials. Tables 3 and 4 identify the reference material to be used with candidate materials for qualification testing and the reference materials to which the respective candidates are compared for performance evaluation. For example, a candidate Type 1, Method B, Level 2 system would be used with the D-1 reference dry powder developer and compared to the FP-2PE/FE-B reference system used with the D-1 reference dry powder developer.
Method A (water washable) penetrants, Method A(W) (water washable – water containing) and Methods B and D (post emulsifiable) penetrants/emulsifiers shall be qualified with the reference dry developer D-1. Method C penetrants shall be qualified either on the basis of their performance as Method A, A(W), B, or D materials, or, alternatively, with the reference solvent remover R-2 and reference dry developer D-1.
All developers intended for use with Type 1 (fluorescent) penetrant materials, except Form f (special application), shall be qualified with the reference Level 4, Method B penetrant/emulsifier system S-FP-4PE/FE-B (see Tables 1 and 2). All developers intended for use with Type 2 (visible) penetrant materials, except Form f, shall be qualified with the Type 2 reference penetrant and Method B emulsifier VP-PEPENE-B. Form f developers shall be qualified in accordance with 3.2.1.5.SAE AMS 2644H pdf free download.
