What is PD IEC TS 62257‑12‑1 about?
PD IEC TS 62257-12-1 is the first part of the multi-series International standard that discusses renewable energy and hybrid systems for rural areas.
PD IEC TS 62257‑12‑1 specifies the framework for creating a product specification for lamps and lighting appliances to serve as the basis for evaluating quality for a particular context. Product specifications include minimum requirements for quality standards, warranty requirements, and/or performance criteria. products are compared to specifications based on test results and other information about the product.
PD IEC TS 62257‑12‑1 applies to lamps and lighting appliances for off-grid electricity systems that have the following characteristics:
- Power supply AC nominal voltages up to 250 V
- Power supply DC nominal voltages up to 48 V
- The light source is CFL, linear fluorescent, or LED
- Operation of the lamp or lighting appliance does not require any components to be supplied by the testing laboratory other than lamp holders, wire, connectors, and a power supply
- The lamp or lighting appliance does not include a battery or energy source (for example, a photovoltaic module or electromechanical generator)
Who is PD IEC TS 62257‑12‑1 for?
PD IEC TS 62257‑12‑1 on off-grid renewable energy products is relevant to:
- Market support programs that support the off-grid lighting market with financing, consumer education, awareness, and other services
- Manufacturers and distributors that need to verify the quality and performance of off-grid renewable energy product
- Bulk procurement programs that facilitate or place large orders of products
- Trade regulators such as government policymakers and officials who craft and implement trade and tax policy
- Renewable energy organizations and institutions
Why should you use PD IEC TS 62257‑12‑1?
A hybrid renewable energy system (HRES) works independently or can be grid-connected and consists of one renewable energy source and one conventional energy source or more than one renewable with or without conventional energy sources.
PD IEC 62257-12-1 provides technical guidelines for designing, building, testing, and maintaining off-grid renewable energy and hybrid systems.
PD IEC TS 62257‑12‑1 benefits the user by connecting them with good quality options in the off-grid renewable energy products market to choose the right system for the right place and to design the system as well as to operate and efficiently maintain the system.
PD IEC TS 62257-12-1 provides guidelines for off-grid products that will ensure safety, sustainability, and cost reduction. The main objective is to support the capabilities of households and communities that use small renewable energy and hybrid off-grid systems.
Overall, PD IEC TS 62257-12-1 provides a quality assurance framework including product specifications (a framework for interpreting test results) and tests methods that contribute to improving the quality and efficiency of off-grid renewable energy products.
What’s changed since the last update?
PD IEC TS 62257‑12‑1:2020 supersedes PD IEC/TS 62257‑12‑1:2015, which is withdrawn. PD IEC TS 62257‑12‑1:2020 includes the following significant technical changes concerning the previous PD IEC/TS 62257‑12‑1:2015:
- Annex A and Annex B were combined into a single Annex A to eliminate duplicate tables and simplify PD IEC TS 62257‑12‑1
- Annex A in this third edition now covers recommendations and requirements for both market support programs and bulk procurement programs.
- Annex A provides specific examples for quality standards, warranty requirements, and performance criteria for off-grid lighting products
