SIST EN 4057-100:2009

Overview

EN 4057-100:2006 is the general part of the CEN aerospace series that specifies the general requirements and test procedures for cable ties used in aircraft harnesses. It sets the baseline conditions, specimen preparation and reporting rules used by the more specific test parts in the EN 4057 series. Accessories such as mounting brackets, identification tags or reusable cable ties are excluded from this part.

Key Topics

• Scope and exclusions: Applies to single-use cable ties for aircraft harnesses; excludes accessories and reusable types.
• Normative references: Relies on EN 4056-001 (technical specification for cable ties) and the other parts of EN 4057 (test methods).
• Definitions: Uses definitions established in EN 4056-001.
• Specimen preparation: Outlines conditioning and storage prior to testing, including chamber conditioning and airtight storage before test fixture installation.
• Installation and tooling: Requires installation with a qualified application tool set to the tension specified in the applicable product standard.
• Atmospheric conditions for testing: Defines normal laboratory conditions, with tests normally carried out at a temperature of (20 ± 5) °C (dispute condition: 23 ± 2 °C) and relative humidity limits.
• Reporting requirements: Specifies required report items (see below).

Applications

This general test-methods standard is used by:

• Aerospace manufacturers and harness assemblers to validate cable tie performance and conformity.
• Test laboratories performing environmental, mechanical and visual assessments of cable ties.
• Procurement and quality teams requiring consistent acceptance criteria for harness components.

Practical benefits include consistent test preparation, repeatable results across laboratories, and a clear structure for reporting key characteristics that affect safety and durability in aerospace harness installations.

Important Reporting Items

When reporting test results under EN 4057-100:2006 include:

• Approved drawing (reference)
• Materials and colours
• Type and size code
• Application tool type and application torsion/tension values
• Test results (with relevant environmental or mechanical test data)

Related Standards (EN 4057 series)

EN 4057-100 references the detailed test parts used to verify specific properties. Examples include:

• General tests: EN 4057-201 (Visual examination), EN 4057-202 (Mass and dimensions)
• Environmental tests: EN 4057-301 to EN 4057-307 (salt mist, flammability, fluids, heat ageing, UV, etc.)
• Mechanical tests: EN 4057-401 to EN 4057-407 (loop tensile strength, life cycle, low temperature installation, locking retention, tool verification)

For specification and procurement, pair EN 4057-100 with EN 4056-001 (technical specification) and the specific EN 4057 test parts appropriate to the material and design of the cable tie.
