Overview

SIST EN 3841-202:2005 is a European standard developed by the European Association of Aerospace Manufacturers (AECMA-STAN) and adopted by CEN. It defines the test methods specifically focused on verifying the dimensions and masses of aerospace circuit breakers. This standard ensures that circuit breakers meet precise physical specifications critical for aerospace applications, contributing to safety, reliability, and interoperability in aerospace electrical systems.

SIST EN 3841-202:2005 is part of the broader aerospace series EN 3841 and must be used in conjunction with EN 3841-100, which covers the general test methods for circuit breakers. The standard was approved across CEN member countries and mandates uniform testing practices to harmonize aerospace component quality across Europe.

Key Topics

• Scope and Purpose
  Specifies the method for verifying the physical dimensions and masses of circuit breakers intended for aerospace use, ensuring compliance with product standards.

• Measurement Methodology
  Physical measurements must be conducted with precision using instruments capable of resolution:

  • Length scale divisions ≤ 0.01 mm
  • Mass scale divisions ≤ 0.1 g

• Compliance Requirements
  Dimensions and weights must conform strictly to the product standards relevant to the specific circuit breaker model.

• Standards Interrelation
  This document works alongside EN 3841-100, where general test methods for circuit breakers are outlined, framing EN 3841-202 as a focused methodology for physical verification.

Applications

• Aerospace Manufacturing
  Manufacturers of aerospace circuit breakers use EN 3841-202 to standardize quality control checks on product dimensions and mass, critical for equipment fitting and weight considerations.

• Quality Assurance
  Aerospace quality assurance teams apply the measurement methods described in EN 3841-202 as part of conformity testing, ensuring parts meet exact specifications before assembly or deployment.

• Component Certification
  Certification bodies and testing laboratories rely on this standard to evaluate circuit breakers during type approval or routine inspections.

• Design and Engineering
  Aerospace engineers reference EN 3841-202 to comply with dimensional accuracy requirements when designing circuit breakers for electrical distribution systems in aircraft.
