Overview

SIST EN 3102:2013 is a European standard published by CEN that specifies the test method for determining the low-temperature flexibility of aerospace sealants. This test assesses the operability and performance of a cured sealant when subjected to bending loads at low temperatures. It is crucial for ensuring sealants used in the aerospace sector maintain integrity and resist cracking under cold environmental conditions, which can affect safety and durability of aerospace components.

Key Topics

• Test Purpose
  Evaluate the resistance of cured sealants to cracking, detachment, or other damage during and after bending at low temperatures.

• Scope
  Covers the bending load test method applied to cured sealant-coated strips of substrate material, typically aluminum alloy, under standardized conditions.

• Test Setup

  • Use of a tensile testing machine capable of controlled bending cycles at a speed of 960 mm/min.
  • A cold chamber to maintain a test temperature typically at -55 ± 3 °C.
  • Test pieces consist of a 1.0 mm thick, 70 mm by 150 mm metal strip with a 2.5 mm thick coat of sealant applied on one side.

• Procedure
  After curing, the test specimen undergoes 130 bending cycles of ± 20 mm displacement at low temperature, simulating real operational stresses.

• Exposure Conditions
  Various pre-test exposure methods (dry heat, test fluids) simulate environmental aging effects on sealant performance.

• Evaluation Criteria
  Visual inspection for signs of cracks, detachment, or other damage after completing the bending test.

• Documentation
  Test reports must detail product information, test conditions, exposure, results, and any deviations from the standard.

Applications

• Aerospace Sealant Quality Control
  SIST EN 3102:2013 is primarily utilized by aerospace manufacturers and suppliers to verify the flexibility and durability of sealants under low-temperature conditions relevant to high-altitude or cold climate operations.

• Material Certification
  Ensures sealant materials comply with international safety standards for usage in aircraft structures, fuel systems, and other critical aerospace components.

• Product Development
  Provides benchmark testing for new sealant formulations aiming to improve performance against thermal stress and environmental aging.

• Regulatory Compliance
  Compliance with this standard helps meet industry regulations and facilitates product acceptance across European aerospace markets.

Related Standards

• EN 2090: Aerospace series - Aluminium alloy AL-P2024-T3
  Defines the substrate material requirements for test pieces used in EN 3102.

• ISO 1817: Rubber, vulcanized - Determination of the effect of liquids
  Employed for exposure fluids that may affect sealant performance prior to flexibility testing.

• ISO 7500-1: Metallic materials - Verification of static uniaxial testing machines
  Ensures tensile testing machines used in EN 3102 meet precision and calibration requirements.
