ASTM E1417/E1417M-21 rus PDF

Full title and description

ASTM E1417/E1417M-21 — Standard Practice for Liquid Penetrant Testing (including editorial amendment E1417/E1417M-21e1). This practice establishes minimum requirements and basic process controls for performing liquid penetrant (dye penetrant and fluorescent) examinations of nonporous metal and nonmetal components to detect surface-connected discontinuities such as cracks, laps, cold shuts, lack of fusion, porosity and corrosion.

Abstract

This standard defines the penetrant examination methods and process-control checks (including system performance checks, material checks, lighting and developer use) required to obtain reliable liquid penetrant examination results. It is written to be specified on drawings or contracts and is intended to be supplemented by detailed procedures and personnel qualifications. Key editorial updates in the 2021 revision address UV‑A terminology, LED lamp warmup exceptions, process-control frequencies and other procedural clarifications.

Scope

This practice establishes minimum requirements for conducting liquid penetrant examinations of nonporous metal and nonmetal components for in‑process, final, and maintenance (in‑service) inspections. It applies to detection of discontinuities that are open to and communicate with the surface. The standard clarifies unit systems (SI and inch‑pound used independently), cautions about elevated temperatures and effects on nonmetallic materials, and directs that detailed procedures and safety practices be established by the user organization.

Key topics and requirements

• Definitions and terminology updates (e.g., use of "UV‑A" in place of "blacklight").
• Penetrant application and removal methods (including Method A water‑washable and other removal practices) and developer application.
• System performance checks, material quality checks, and required frequencies for process control and calibration (several frequencies revised in the 2021 edition).
• Requirements and exceptions for lighting sources (LED UV‑A lamps exempted from the 10‑minute warmup required for older lamp types).
• Guidance on handling extended shelf life for penetrant materials and on investigating discrepancies between in‑use and new materials.
• Notes on preventing cross contamination of penetrant types and on special‑lighting requirements for fluorescent penetrant inspection.

Typical use and users

Used by NDT laboratories, manufacturing quality/control departments, aerospace and defense contractors, maintenance and inspection personnel, and NDT Level II/Level III specialists to define baseline penetrant testing requirements for procurement, inspection procedures and contract specifications. Organizations rely on this practice to standardize penetrant testing acceptance, process controls and personnel/lighting requirements.

FAQ

Q: What is this standard?

A: ASTM E1417/E1417M-21 is a Standard Practice that establishes the minimum requirements and process‑control elements for liquid penetrant (dye and fluorescent) examinations of nonporous components.

Q: What does it cover?

A: It covers penetrant application and removal methods, developer use, lighting and UV‑A requirements, system and material performance checks, recommended frequencies for process control/calibration, and notes on safety and material compatibility. It is intended to be supplemented with detailed written procedures and personnel qualification instructions.

Q: Who typically uses it?

A: NDT technicians and supervisors (Levels II/III), quality/inspection engineers, maintenance and manufacturing inspection teams, and organizations that specify nondestructive testing requirements in contracts and drawings.

Q: Is it current or superseded?

A: The 2021 revision (E1417/E1417M‑21) with the editorial/amendment release E1417/E1417M‑21e1 is the current published form of this practice; earlier editions (for example E1417/E1417M‑20 and prior) have been superseded by the 2021 release. Users should verify they have the E21e1 (or latest) document before applying the practice.
