EN 2497:1989

Overview

EN 2497:1989 is a CEN aerospace series standard that specifies the process schedule and requirements for dry abrasive blasting of titanium and titanium alloys used in aerospace constructions. The method described is applicable to the pretreatment of titanium components and to the qualification tests of adhesives on these materials. The standard helps ensure consistent surface preparation and repeatable procedures suitable for aerospace manufacture and testing.

Key Topics

• Scope and applicability: Defines where dry abrasive blasting is an acceptable pretreatment method for titanium and its alloys in aerospace use.
• Process schedule: Presents the sequence of operations and controls required to carry out dry abrasive blasting as a pretreatment step (e.g., preparation, blasting operation, post-blast handling).
• Quality requirements: Describes required outcomes and quality checks to verify that blasted surfaces meet the conditions necessary for subsequent bonding or coating operations.
• Adhesive qualification: Specifies how the blasting method is used in the preparation of test specimens and in procedures for qualifying adhesives on titanium substrates.

Applications

EN 2497:1989 is directly relevant to organizations and activities that include:

• Aerospace manufacturers and suppliers preparing titanium parts for bonding, coating or assembly.
• Surface treatment and pretreatment operations where consistent, controlled blasting is required prior to adhesive bonding.
• Test laboratories and quality departments performing adhesive qualification and verification on titanium substrates.

Practical benefits when implementing this standard include:

• Consistent surface preparation across production batches.
• Traceable process schedules that support quality assurance and regulatory compliance.
• Support for reliable adhesive testing and qualification activities.

Related Standards

• Other CEN and aerospace series standards covering coatings, surface treatments and adhesive qualification processes (refer to your organization's standards index or CEN database for specific cross-references).
• Industry guidance and quality management standards used alongside EN 2497:1989 to document procedures, personnel training and testing protocols.

When adopting EN 2497:1989, organizations should integrate the specified process schedule into work instructions, ensure operator training on blasting controls and document verification steps for adhesive qualification. This alignment helps maintain aerospace-grade consistency and supports certification and acceptance of titanium components prepared by dry abrasive blasting.
