IEC TS 62257-9-5:2016

Recommendations for renewable energy and hybrid systems for rural electrification - Part 9-5: Integrated systems - Selection of stand-alone lighting kits for rural electrification

IEC TS 62257-9-5:2016(E) applies to stand-alone rechargeable electric lighting appliances or kits that can be installed by a typical user without employing a technician. It presents a quality assurance framework that includes product specifications, test methods, and standardized specification sheets. This new edition includes the following significant technical changes with respect to the previous edition:
- battery test methods updated to harmonize with existing IEC standards, sequence of testing changed to allow the battery to be charged using the product's charge controller prior to the full-battery run time test;
- limits on total series resistance of the test apparatus added to test procedures.

Overview

IEC TS 62257-9-5:2016 provides recommendations and a quality-assurance framework for stand‑alone rechargeable electric lighting appliances and kits intended for rural electrification. It applies to kits that can be installed by a typical user without a technician and defines product specifications, test methods and standardized specification sheets (SSS) to support selection, procurement and market monitoring of off‑grid lighting products.

This edition (2016) includes important technical changes:

• Battery test methods updated to harmonize with existing IEC standards and a revised test sequence that allows the battery to be charged using the product’s charge controller prior to full‑battery run‑time testing.
• Limits on total series resistance of the test apparatus added to the test procedures.

Key Topics and Requirements

• Scope and system limits: Definitions for components, component categories, lighting elements and additional system elements suitable for rural contexts.
• Product specification framework: Template, tolerances, quality criteria and warranty requirements to enable consistent procurement and comparison.
• Quality assurance principles: Requirements for design, manufacture, durability, workmanship and end‑user support.
• Battery performance and testing: Updated battery test methods and sequencing to reflect real‑world charging behavior through the product’s charge controller.
• Electrical, light‑output and performance metrics: Standardized ways to measure and report lumen output, run time, charging efficiency and other electrical characteristics.
• Test programs and methods: Laboratory requirements, sampling, recommended test programs (initial screening, market checks, accelerated verification) and reporting formats.
• Standardized specification sheets (SSS): Structured public data sheets to present verified product performance for buyers and programmes.
• Annexes covering SSS guidelines, manufacturer self‑reported information, sampling procedures and visual screening.

Applications

• Procurement and tendering: Create objective performance and warranty criteria for buying off‑grid lighting kits.
• Product qualification and market support: NGOs, development agencies and governments can use the framework to qualify products for subsidy or distribution programmes.
• Quality testing and certification: Test laboratories and market surveillance bodies use the test methods and sampling procedures for verification.
• Manufacturer guidance: Helps product designers and manufacturers align product data and testing with buyer expectations.

Who Should Use This Standard

• Procurement officers, programme managers and policymakers for rural electrification
• NGOs and international development agencies deploying off‑grid lighting
• Manufacturers and product designers of stand‑alone lighting kits
• Test laboratories and market surveillance authorities

Related Standards

This TS is harmonized with other IEC standards for batteries, solar modules and electrical testing; it is intended to be used alongside applicable IEC battery and photovoltaic test standards when specifying and verifying off‑grid lighting products.

Keywords: IEC TS 62257-9-5, stand-alone lighting kits, rural electrification, off-grid lighting, battery test methods, quality assurance, standardized specification sheets.
