Meeting IEC standards isn't just a paperwork exercise-it's how you prove your PV and LED products will survive real outdoor and indoor life. Below is a concise guide to what the two standards require and how LIB's chambers map directly to those requirements.
1) IEC 61215 for PV Modules - What needs to be tested
Core environmental stresses typically include:
Thermal Cycling (TC): cycling between about –40 °C and +85 °C, 50 or 200 cycles.
Humidity-Freeze (HF): repeated transitions between 85 °C / 85 %RH and –40 °C (10 cycles).
Damp Heat (DH): long-soak at 85 °C / 85 %RH for 1,000 h (often written "85/85/1000").
These stresses are intended to reveal failure modes such as backsheet delamination, EVA yellowing, corrosion, and seal failures before modules go to field.

LIB's solution for IEC 61215 damp heat & related stresses
Product: Damp Heating Chamber for PV Module

Purpose-built for DH: supports 85 °C / 85 %RH long-term tests (typ. 1,000–3,000 h).
Temperature & humidity range: –20/–40/–60/–120 °C to +150 °C, 20–98 %RH with tight stability (≤ ±0.5 °C / ±2 %RH), enabling TC, HF profiles and 85/85 soaks per your test plan.
PV-specific fixturing: adjustable multi-panel racks (4/6/8/10/12 pcs; up to ~1 m × 2 m per panel) for parallel testing and realistic orientations.
Reliability by design: SUS304 mirror-finish workroom, continuous air circulation, large water storage/auto-refill to sustain long runs.
Process control: programmable controller, user-defined T/RH gradient curves, remote supervision, alarms; 3-year warranty and 24/7 remote diagnostics.
Typical IEC-61215 DH workflow with LIB
Load modules on adjustable rack; connect monitoring leads via Ø50 mm cable port(s).
Program 85 °C / 85 %RH for 1,000 h; enable data logging and remote notifications.
Perform mandated inspections and electrical checks before/after per your qualification plan.
2) IEC 62717 for LED Modules - What needs to be tested
Scope: performance requirements for LED modules (not lamps/luminaires), covering electrical/photometric characteristics, luminous-flux maintenance (life) and associated endurance tests under specified temperature/humidity conditions (see Annex A). The consolidated edition IEC 62717:2014+A1:2015+A2:2019 refines metrics such as luminous-flux maintenance.
In short: you must characterize module performance, then verify durability and lumen-maintenance under controlled thermal/humidity stress conditions defined by the standard.

LIB's solution for IEC 62717 thermal & humidity endurance
Product: Temperature Humidity Environmental Chamber

Wide T/RH envelope: –20/–40/–70 °C to +150 °C, 20–98 %RH; stability ±0.5 °C, humidity deviation ±2.5 %RH-ideal for Annex-A endurance profiles and steady-state life testing.
Right-sized models: 100 L / 225 L / 500 L / 1000 L standard volumes, plus custom builds to fit boards, strips, and array modules with control gear.
Data & traceability: programmable controller, RS-485/Ethernet/Wi-Fi for remote monitoring, real-time data transmission, and recipe management.
Usability details: heated anti-fog viewing window, LED lighting, customizable Ø50 mm cable ports, special vertical sample holders, optional glove ports.
Typical IEC-62717 endurance workflow with LIB
Mount LED modules, route leads through the cable port, and stabilize at the specified ambient or case temperature.
Run the temperature/humidity endurance profile per Annex A while logging electrical/photometric checkpoints.
Execute luminous-flux maintenance measurements at required intervals to demonstrate the rated maintenance factor.
