Founding - Liquid penetrant testing - Part 2: Investment castings

This European Standard specifies a liquid penetrant testing method for castings produced by investment casting for general purposes.
NOTE   Investment casting is sometimes referred to as lost-wax casting.
This European Standard applies to all cast metals, except copper-tin and/or copper-tin-lead alloy castings, where copper is the major constituent (see EN 1982 [3]).

Gießereiwesen - Eindringprüfung - Teil 2: Feingussstücke

Diese Europäische Norm legt ein Verfahren zur Eindringprüfung an Feingussstücken fest, die nach dem Feingießverfahren für allgemeine Zwecke hergestellt wurden.
ANMERKUNG   Das Feingießverfahren wird gelegentlich auch als Wachsausschmelzverfahren bezeichnet.
Diese Europäische Norm gilt für alle Gussmetalle mit Ausnahme von Gussstücken aus Kupfer-Zinn- und/oder Kupfer-Zinn-Blei-Legierungen mit Kupfer als Hauptbestandteil (siehe EN 1982 [3]).

Fonderie - Contrôle par ressuage - Partie 2: Pièces en moulage de précision (cire perdue)

La présente Norme européenne spécifie une méthode de contrôle par ressuage pour les pièces moulées produites par moulage de précision (cire perdue) pour usage général.
NOTE   Le moulage de précision est parfois appelé moulage en cire perdue.
La présente Norme européenne s'applique à tous les métaux moulés, à l'exception des pièces moulées en alliages cuivre-étain et/ou cuivre-étain-plomb, où le cuivre est l'élément majoritaire (voir EN 1982 [3]).

Livarstvo - Preiskava s penetrirno tekočino - 2. del: Precizijsko uliti ulitki

Ta evropski standard določa način preiskav s penetrirnimi tekočinami za ulitke, ki so jih proizvedli s precizijskim litjem za splošne namene.
OPOMBA: Precizijsko litje se včasih imenuje tudi tehnika izgubljenega voska.
Ta evropski standard se uporablja za vse lite kovine, z izjemo ulitkov iz zlitin bakra in kositra in/ali bakra, kositra in svinca, pri katerih je glavna sestavina baker.

Overview

EN 1371-2:2015 - Founding: Liquid penetrant testing - Part 2: Investment castings specifies a liquid penetrant (penetrant) testing method for castings produced by investment casting (also called lost‑wax casting). It sets out how to perform penetrant inspection on agreed casting surfaces, defines types of penetrant indications and severity levels, and describes acceptance, classification, retesting, post‑cleaning and reporting requirements. The standard applies to all cast metals except copper‑tin and copper‑tin‑lead alloys where copper is the major constituent (see EN 1982).

Key topics and technical requirements

• Scope and applicability: Targets investment castings for general purposes; exclusions noted for specific copper alloys.
• Test method: Implements penetrant testing in accordance with EN ISO 3452 series; choice of penetrant and operating mode is agreed between manufacturer and purchaser.
• Operator qualification: Testing must be performed by qualified NDT personnel - qualification scheme to be agreed (e.g. EN ISO 9712 or EN 4179).
• Surface preparation: Surfaces must be clean and free from contaminants. Shot blasting is not recommended; if used it must be light and may require follow‑up chemical etching to avoid sealing defects.
• Viewing and magnification: Inspection by naked eye or minimum 3× magnification, with viewing conditions per EN ISO 3059.
• Indication types & definitions:
  • Linear (LP): L ≥ 3W
  • Non‑linear isolated (SP) and clustered (CP): L < 3W
  • Aligned (AP): criteria for linear or non‑linear alignments
• Severity levels & acceptance: Tables define minimum indication sizes to be considered for each severity level. Classification uses a 25 mm × 25 mm reference frame (proportional adjustment for smaller castings).
• Documentation: Test report requirements follow EN ISO 3452‑1; Annex E provides a model report. Informative annexes include reference figures and guidance on discontinuity types.

Practical applications and users

EN 1371-2 is used where reliable surface defect detection on investment castings is required:

• Foundries producing precision investment castings (lost‑wax)
• NDT technicians and inspection teams performing liquid penetrant testing
• Quality managers and QA/QC engineers specifying acceptance criteria for cast parts
• Purchasers and design engineers defining inspection requirements in procurement documents
• Industries using precision cast metal components (automotive, energy, tooling, specialist engineering)

Related standards

• EN ISO 3452‑1, ‑2, ‑5, ‑6 (general penetrant testing principles and material testing)
• EN 1371‑1 (Part 1: sand, gravity die and low pressure die castings)
• EN ISO 3059 (viewing conditions)
• EN ISO 9712 / EN 4179 (personnel qualification)
• EN 1370 (visual surface condition assessment)
