Overview
EN 1370:2011 - Founding: Examination of surface condition is a CEN European Standard that specifies methods for assessing the surface condition (roughness and surface discontinuities) of castings. It applies to all cast metals and casting processes except die casting. The standard replaces earlier editions (EN 1370:1996 and EN 12454:1998) and consolidates procedures for visual-tactile comparators, dimensional classification of defects, and optional instrumented measurements.
Key Topics and Requirements
- Scope & applicability: Applies to as-cast, shot-blasted, ground or otherwise finished cast surfaces for all alloys except die-castings.
- Comparators: Uses positive replica comparators (BNIF and SCRATA sets) as the primary means to classify surface roughness and detect discontinuities. Typical comparator sizes: SCRATA ~100 × 150 mm, BNIF ~110 × 160 mm.
- Surface roughness: Visual-tactile comparison is the preferred method; roughness categories are mapped to comparator levels (examples and Ra guidance are provided in the standard). Instrumented methods (stylus contact or optical non‑contact) may be used only by prior agreement between purchaser and manufacturer.
- Surface discontinuities: Defines classification by dimensions (height/depth H and largest length L) with severity levels (VD1–VD8) and comparator-based categories for steel and iron (VC levels). Steps, laps, inclusions, porosity and similar defects are covered.
- Inspection protocol: At ordering, parties must agree on category/severity level, unacceptable discontinuities, areas to inspect, sample size, and inspection stage. Examinations must be performed by trained personnel under adequate lighting.
- Documentation: Manufacturers should record casting identification, inspector name/qualification, comparator/instrument references, designated areas/levels, and inspection results.
Applications and Who Uses It
EN 1370:2011 is used by:
- Foundries and casting manufacturers for quality control and contractual acceptance criteria
- Purchasing/specification engineers to define surface finish and allowable defects on drawings
- QA/QC inspectors and NDT technicians performing visual/tactile inspections
- Tooling and finishing departments selecting moulding, dressing or surface treatments
Practical uses include selecting appropriate moulding processes (sand, shell, lost-wax, etc.), agreeing acceptance criteria for external customers, and guiding repair/finishing actions (grinding, welding) based on defect severity.
