  Acceptance Criteria for Liquid Penetrant Testing -LPT as per ASME , AWS and API standards Liquid penetrant testing  simply called as PT. Sometimes Dye Penetrant Testing is a surface defect detection NDT  method and is more sensitive to all kind of surface defects, such as cracks , porosity, hot tears, laps, etc. The NDT methods are trained by NDT Training Institutes with their NDT courses, and the LPT is one among the basic Non Destructive Testing Methods. Various international standards for Liquid Penetrant Testing are as below ASME Boiler and Pressure Vessel Code BPVC- Section V – Article 6 and Article 24 ASTM E-1417 (ASTM Standard) ASTM E-165 (Penetrant Testing Standard for general Industry ASTM Standard) ISO 3452-1 (ISO Standard) SAE AMS 2644 (Aerospace Standard) AS 2062 (Australian Standard ) DIN EN 571 The Indications are evaluated as per Clients Acceptance Criteria or the Product Standard in conformance with the clients acknowledgement . Few examples of product standards are a
