Discussion Points for Today s Webinar Product Safety Certification Process Overview Key Product Safety Standards for Solid-State Lighting Products How to Efficiently Navigate Through the Product Safety Certification Process Don t Forget Performance!
Product Safety Certification Product Safety Compliance is a legal requirement worldwide. Per OSHA requirements, electronic equipment is acceptable if listed by a Nationally Recognized Testing Laboratory (NRTL). NRTLs are qualified private organizations that meet the requirements in OSHA regulations under 29 CFR section 1910.7 to perform independent safety testing and product certification.
Basic Steps to Product Certification Step # 1 Product Construction / Design Review Review: Bill of Materials Individual Component & Material Ratings Use of Recognized or Unrecognized Components/Materials Product Design Drawings Spacings / Dimensional Requirements Determination of Applicable Tests per Standard
Basic Steps to Product Certification Step # 2 Product Testing Product to be tested per the applicable requirements of the standard. May include tests such as: Temperature Tests Electrical Tests Dielectric Tests Strain Relief Tests Environmental Tests (Wet Locations) Mechanical Tests
Basic Steps to Product Certification Step # 3 Issuance of the Formal Test Report & Authorization to Mark (ATM) Permission to Label Product with Applicable Safety Mark from an NRTL
Basic Steps to Product Certification Step # 4 Participate in NRTL Follow Up Services Program Ongoing manufacturing facility inspections (quarterly / monthly) to ensure consistent design, production, and labeling of the product. Maintain / Update Files to Remain Current with Latest Revision of Applicable Stna
Applicable Safety Standards for LED Lighting Products
Product Safety Standards for LED Lighting Existing Lighting Standards still apply for LED Lighting, but evaluations are now conducted incorporating: UL 8750 Safety Standard for LED Lighting
Product Safety Standards for LED Lighting Fixed Luminaires UL 1598 / CSA C22.2 # 250 Luminaires (+ UL 8750) UL 1573 Stage & Studio Lighting (+ UL 8750) UL 1574 Track Lighting (+ UL 8750) Portable Luminaires UL 153 Portable Electric Lamps (+ UL 8750) UL 1993 Self-Ballasted Lamps and Lamp Adapters (+ UL 8750) 3rd Edition, August 28, 2009 Added requirements covering LED Driver Circuitry Added requirements / limits for LED Light Sources Now Harmonized with ANCE (Mexico) and CSA (Canada) Replacement LED Lamps
Product Safety Standards for LED Lighting Specialty Luminaires UL 48 Electric Signs (+ UL 8750) UL 676 Underwater Lighting Fixtures (+ UL 8750) UL 844 Fixtures for Use in Hazardous (Classified) Locations (+ UL 8750) UL 924 Emergency Lighting and Power Equipment (+ UL 8750) UL 1786 Nightlights (+ UL 8750) UL 1838 Low Voltage landscape Lighting Systems (+ UL 8750) UL 1994 Low-level Path Marking and Lighting Systems (+ UL 8750) UL 2108 Low Voltage Lighting Systems (+ UL 8750) UL 2388 Flexible Lighting Products (+ UL 8750)
UL 8750 What Does It Cover? LED Equipment that is an integral part of a Luminaire, including: LED Drivers LED Controllers LED Arrays LED Modules LED Packages The requirements found in UL 8750 are intended to supplement those found in the existing luminaire standards previously identified.
UL 8750 Current Status May 2009 UL 8750 1 st Edition was released to the Standards Technical Panel (STP) for Review and Comment July 2009 Closed Ballot Consensus Obtained 150 Comments Received September 2009 Revised Proposed Standard Published Sept. 11, 2009 October 2009 Recirculation / Comment Period Ends Oct. 26, 2009 November 2009 Target for Final Published Standard
How to Efficiently Navigate the Product Safety Certification Process Where Do You Intend to Sell Your Products? What global markets do you wish to enter? Thinking globally from the outset will save you $$$ in the long run!!!
How to Efficiently Navigate the Product Safety Certification Process Design with Compliance in Mind Involve your certification partner at the R&D and Design Phases of your product life cycle. What components will you use? Existing / Proprietary? Material / Component Ratings? Recognized?
How to Efficiently Navigate the Product Safety Certification Process Be Mindful of the Main Safety Concerns with LED Lighting RISK OF ELECTRIC SHOCK RISK OF FIRE BIOLOGICAL HAZARDS
How to Efficiently Navigate the Product Safety Certification Process RISK OF ELECTRIC SHOCK UL 1310 Class 2 Power Supplies Reduced shock and fire hazard due to current and voltage limitation. UL 1012 Power Supplies Other Than Class 2 Must comply with standard insulation and accessibility requirements. Enclose/Barrier live parts to prevent physical contact Insulate live parts with appropriately rated materials Utilize appropriate spacings live and accessible parts
How to Efficiently Navigate the Product Safety Certification Process RISK OF FIRE How will you manage thermal effects of your LED Product? Take into account proximity and spacing of LEDs Material and design for diffuser? Type of enclosure utilized / enclosure flame ratings Installation scenario Thermal dissapation relies on ambient temperature and thermal path design.
How to Efficiently Navigate the Product Safety Certification Process BIOLOGICAL HAZARDS Exposure to Ultra Violet Wavelengths (100 400 nm) are of concern. U.S. & Canada currently do not have mandatory standards or regulations. Organizations such as IESNA, ANSI, CIE, IEC are actively evaluating
How to Efficiently Navigate the Product Safety Certification Process Identify as Many Product Variations as Possible Will allow grouping of similar products into families which may: Minimize total number of samples required for evaluation and testing. Lower total project certification & testing fees. Provide quicker market entry for your entire product line.

Don t Forget Performance!!
Enclosure Testing per IEC 60529 Ingress Protection Testing Ensures your product will withstand varying degrees of Moisture and Dust Intrusion. First Number Second Number IP 0x - No Protection IP x0 - No Protection IP 1x - Objects > 50mm IP x1 - Vertically Dripping Water IP 2x - Objects > 12mm IP x2-75 to 90 Degrees Dripping Water IP 3x - Objects > 2.5 mm IP x3 - Sprayed Water IP 4x - Objects > 1 mm IP x4 - Splashed Water IP 5x - Dust Protected (Vacuum) IP x5 - Water Jets IP 5x - Dust Protected (Non-Vacuum) IP x6 - Powerful Water Jets IP 6x - Dust Tight IP x7 - Effects of Immersion IP x8 - Indefinite Immersion
New Standards Released in 2008 IESNA LM-79-08 - Approved Method for the Electrical and Photometric Testing of Solid- State Lighting Devices (Applies to both LED Luminaires and LED Light Sources to be used in retrofit or replacement scenarios. Does not cover LED Modules, LED Packages or Individual LEDs) Absolute Photometry vs. Relative Photometry Total Luminous Flux (lumens) Luminaire Efficacy (lm/w) Color (Chromaticity, CCT, CRI) Intensity Distribution
New Standards Released in 2008 ANSI C78.377-2008 Specifications for the Chromaticity of Solid-State Lighting Products Specifies recommended chromaticity (color) ranges for White LED s, including Correlated Color Temperatures for SSL Products such as LED Luminaires & Integrated LED Lamps For General Indoor Applications
New Standards Released in 2008 IESNA LM-80-08 - Approved Method for Measuring Lumen Maintenance of LED Light Sources (Applies to LED Arrays, Packages, & Modules only, not Luminaires) Provides test method for Lumen Maintenance (L70 Hours = Time to 70% Lumen Maintenance) Operation of LED Light sources between photometric measurements shall be at three case temperatures: 55C, 85C, and XX (mfrs choice) Test Duration: Minimum of 6,000 hours with measurements at 1,000 hour intervals **NOTE: Standard does not provide guidance regarding predictive estimations or extrapolation. IES TM-21-xx which is currently under development will address this.
