EN 2003-010:2007

Overview

EN 2003-010:2007 is a European standard part of the aerospace series focusing on titanium and titanium alloys. It specifies standardized test methods for sampling intended for the accurate determination of hydrogen content within titanium products. This standard ensures consistent sampling procedures, thereby providing reliable assessment of hydrogen levels-critical for aerospace material performance and safety.

This document is essential for manufacturers, quality control labs, and aerospace engineers involved in the production and testing of titanium alloys used in aerospace applications. It establishes clear guidelines on the location of test pieces and preparation of analysis samples to avoid contamination and assure representativity of the hydrogen content measurement.

Key Topics

• Sampling Location Guidelines
  The standard outlines precise locations from which test pieces should be extracted, considering the form of the titanium product: sheet, strip, plate, bar, forging stock, casting, and tubes. It emphasizes inclusion of the total thickness or at least one product surface because hydrogen tends to concentrate near surfaces.

• Test Piece Preparation
  To avoid contamination, cutting tools must be clean and dry. Controlled use of abrasive wheels and cutting fluids is allowed only under strict conditions that do not influence hydrogen measurements.

• Analysis Sample Requirements
  Analysis samples are taken from the test pieces and must typically have a mass under 1 gram. They must be thoroughly cleaned, degreased, and dried prior to analysis, ensuring the surface remains metallically clean for accurate hydrogen detection.

• Scope of Application
  This is applicable to titanium and titanium alloy products in delivery condition unless otherwise agreed between manufacturer and purchaser.

Applications

• Aerospace Industry
  Ensures the integrity and safety of titanium components used in aircraft structures and engines by accurately determining internal hydrogen levels, which affect mechanical properties such as ductility and fatigue resistance.

• Quality Control and Inspection
  Provides standardized sampling techniques critical for QC labs tasked with material certification and product acceptance, supporting compliance with aerospace specifications and reducing variability in hydrogen analysis results.

• Material Research and Development
  Supports R&D activities where precise hydrogen measurement in titanium alloys influences the development of new grades and heat-treatment processes.

• Supply Chain Compliance
  Enables raw material and component suppliers to meet customer-specific hydrogen content requirements, ensuring conformity and traceability in aerospace manufacturing.

  Defines the overarching framework and linkage of standards like EN 2003-010 within aerospace metallic materials testing.

• Other EN series standards covering titanium alloys in aerospace may include test methods on mechanical properties, chemical composition, and non-destructive testing to be used complementary to hydrogen content determination.

Practical Value

EN 2003-010:2007 facilitates:

• Consistent and representative sampling leading to reliable hydrogen measurements.
• Minimized contamination risk during sample preparation, improving test accuracy.
• Clear guidance tailored to product forms, accounting for thickness and geometry differences.
• Enhanced material certification processes, vital for aerospace safety and performance.

This standard is indispensable for aerospace stakeholders aiming at high-quality titanium alloy products, helping mitigate risks associated with hydrogen embrittlement and maintaining compliance with international aerospace manufacturing standards.
