IEC 60952-3:2013

Overview

IEC 60952-3:2013 is the international standard that specifies product requirements and the Declaration of Design and Performance (DDP) procedures for aircraft batteries. It applies specifically to nickel-cadmium and lead-acid batteries used in aviation, including vented and valve-regulated cells or monoblocs. This third edition, published by the International Electrotechnical Commission (IEC), replaces the earlier 2004 edition, incorporating updates to better define performance declarations and specification requirements between suppliers and purchasers. The standard ensures that aircraft batteries meet rigorous airworthiness and quality standards essential for safe aerospace operations.

Key Topics

• Product Specification Requirements The standard mandates clear, mutual agreement on product specifications between battery manufacturers and purchasers. Each battery design must have a product specification aligned with IEC 60952 parts 1 and 2, covering general test, performance, design, and construction criteria.

• Declaration of Design and Performance (DDP) DDP is a formal document detailing the battery’s design, construction, performance capabilities, and any limitations. It includes test data or analysis that verifies battery compliance. The DDP must be authenticated by the manufacturer’s technical manager and specify any departures from standard requirements.

• Performance and Verification The performance declarations are based on testing, calculation, or similarity analysis and are not absolute but indicative of the battery’s operational capabilities. Verification involves adherence to test procedures specified in IEC 60952-1, with any alternate methods declared transparently.

• Templates for Specification and DDP Annexes in the standard provide templates for purchaser product specifications and for the DDP document, facilitating standardized communication and clear documentation between manufacturers and customers.

• Scope and Application Batteries covered serve general and specific aerospace purposes, requiring conformance to airworthiness standards per IEC 60952-1. The standard recognizes additional national or industry requirements (e.g., AECMA, SAE) and can be used as a framework to meet those needs.

Applications

IEC 60952-3:2013 is essential for aerospace battery manufacturers, system integrators, and purchasers involved in:

• Aircraft Battery Design and Manufacturing Ensuring that designs meet internationally recognized performance and safety standards to qualify batteries as airworthy.

• Supplier-Purchaser Agreements Supporting clear and documented agreements on product specifications and performance declarations, reducing disputes and enhancing transparency.

• Battery Qualification and Certification Assisting in compliance documentation required for certification bodies and regulatory authorities overseeing aircraft equipment safety.

• Aerospace System Integration Providing detailed battery performance data to system designers for integration with aircraft power management and charging systems.

• Maintenance and Lifecycle Management Defining operational limitations and useful life to inform maintenance schedules and battery replacement planning.
