General Information
Overview
EN 6018:2017 is a European Standard developed by CEN outlining the precise test method for determining the density of metallic materials using the displacement method. This standard is part of the aerospace series of test methods and serves a critical role in ensuring accurate material characterization for aerospace and defense industries.
The displacement method defined by EN 6018:2017 focuses on measuring the density of metallic samples by assessing the weight difference when immersed in a suitable liquid. This approach is recognized for its reliability and accuracy, contributing significantly to quality control and material verification processes in highly regulated sectors.
Key Topics
Scope: Specifies the procedure for determining metallic material density via displacement.
Test Medium: Requires the use of distilled water or an appropriate liquid, potentially with up to 0.1% wetting agent to prevent air bubble formation on samples.
Equipment: Utilizes a high-precision weighing machine with an error limit of 0.0001 g.
Measurement Process:
- Weigh sample in air (mass m₁).
- Weigh sample immersed in test liquid (mass m₂).
- Ensure no air bubbles adhere to the sample during immersion.
- Determine liquid density (ρ_F) using an aerometer before testing.
Evaluation: Calculates sample density (ρ_3) using the formula:
[ ρ_3 = \frac{m_1 \cdot ρ_F}{m_1 - m_2} ]
Accuracy Considerations: Emphasis on minimizing errors such as air bubble adhesion and using liquid densities verified prior to each test.
Applications
The density determination method prescribed in EN 6018:2017 is essential for:
- Material Verification in Aerospace: Ensures that metallic components meet specified density requirements critical for performance and safety.
- Quality Control: Facilitates batch testing and production monitoring of ferrous and non-ferrous metal alloys.
- Research and Development: Assists engineers in material characterization for new aerospace components.
- Certification and Compliance: Supports manufacturers in meeting stringent aerospace industry standards by providing reproducible, standardized density measurement procedures.
- Failure Analysis: Helps identify density anomalies in materials that may indicate defects or non-conformities.
