RFQ4-15

Laboratory Testing for Off-Grid Televisions

Introduction

CLASP is an international non-profit organization whose mission is to improve the environmental and energy performance of the appliances and related systems we use every day, lessening their impacts on people and the world around us. CLASP develops and shares transformative policy and market solutions in collaboration with global experts and local stakeholders.

CLASP serves as the Operating Agent for the several programs of the Global Lighting & Energy Access Partnership (Global LEAP), an initiative of the Clean Energy Ministerial (CEM) to catalyze and support commercial markets that deliver clean energy access products and services to un- and under-electrified communities throughout the developing world. Global LEAP does this by developing product quality assurance frameworks, promoting demand-side super-efficiency, and encouraging collaboration among donors and other institutions.

To support current and future programmatic efforts, and the development of the global off-grid appliance market, Global LEAP is developing off-grid appliance test methods. To gauge the costs and feasibility of these methods, CLASP is soliciting off-grid television testing cost estimates from qualified laboratories. Several Global LEAP programs will require a significant amount of laboratory testing over the next several years, and laboratories that respond to this Request for Quotation will be shortlisted for the forthcoming testing activities. Information related to the background, test parameters and methods, submittals, and timeline for this RFQ is provided below.

Background

Televisions are one of the most demanded appliance categories in un- and under-electrified regions where off-grid energy systems are used. However, a key challenge to the off-grid television market, and thus to related energy access goals, is the damage to the market caused by low-quality, energy-inefficient, cost-ineffective products. Such products spoil the end-user experience, creating significant barriers to market development.

In response to this challenge, Global LEAP is currently collaborating with off-grid energy industry stakeholders, appliance manufacturers, policymakers and test facilities to develop a test method to evaluate the quality, durability, energy performance and off-grid appropriateness of off-grid televisions. Once established, this test methodology will be utilized by the Global LEAP Outstanding Off-Grid Appliance Awards program and other Global LEAP market transformation programs. It also will be made available to off-grid industry and policy stakeholders.

Global LEAP wants to ensure that testing costs are appropriate and affordable for off-grid market stakeholders. To this end, CLASP is requesting detailed quotes – with line item cost breakdowns for each referenced test method (as listed below) – from qualified test laboratories.

Test Parameters and Methods

The Global LEAP test method for off-grid televisions heavily leverages existing, widely-used (i.e. IEC and ENERGY STAR) television test methodologies. In some cases, the referenced methods are modified so that the test reflects what makes a television appropriate for off-grid application. The detailed parameters, referenced test methods and notes and modifications are provided in Table 1, below.

  • Measure On mode power.

Average On mode power per unit screen area (W/cm2)

Calculated value

  • Average On mode power divided by screen area.

Maximum On mode power per unit screen area (W/cm2)

Calculated value

  • Maximum On mode power divided by screen area

Standby mode power (W)

IEC 62301 Ed 2.0 – 2011:  Clause 5

  • No Modification

Luminance (cd/cm2)

ENERGY STAR® Program Requirements Product Specification for Televisions Test Method (2011): Section 6.2

  • Luminance shall be measured in accordance with the ENERGY STAR method. The results shall be expressed as luminance per unit screen area (cd/cm2)

Physical Ingress Test

IEC 62257-9-5:2013: Clause U.4.3 (Simplified IP inspection for ingress of solid foreign objects)

  • No Modifications

Environmental Test

IEC 60068-2-78

  • Subject television to +40 °C and 95% humidity for 24 hours;
  • Measure On Mode power, standby power and luminance.

Voltage Fluctuation Test

IEC 62087 Ed 3.0 – 2011:  Clause 11;

IEC 62301 Ed 2.0 – 2011:  Clause 5;

ENERGY STAR® Program Requirements Product Specification for Televisions Test Method (2011): Section 6.2

  • Measure On Mode power, standby power and luminance under over-voltage condition (+15% of rated voltage) and under-voltage condition (-15% of rated voltage);

Viewing Angle

  • We currently do not have a suitable test method to test the maximum viewing angle from where the pictures of the television can be viewed. Please suggest a test method and cost to test for viewing angles. 

Additional information on the proposed test method for off-grid televisions is available upon request.
