When outdoor products are exposed to sunlight, heat, and moisture for months or years, their appearance and performance may gradually change. Paint fading, plastic cracking, coating degradation, and material aging can seriously affect product reliability. But how can manufacturers predict these problems before products enter the market?

A Sunshine Carbon Arc Weatherometer provides a controlled laboratory solution by accelerating natural weathering conditions. Using a carbon arc lamp, controlled temperature, and humidity environment, it helps engineers evaluate how materials respond to long-term exposure and improve product durability before mass production.

This article explains what a Sunshine Carbon Arc Weatherometer is, how it works, which international standards it meets, and how industries can use it for accurate accelerated aging evaluation. It also introduces a real customer application, compares carbon arc and xenon arc weathering technologies, and provides practical guidance for selecting the right weathering test equipment.

1. Carbon Arc Light Exposure Simulation

A Sunshine Carbon Arc Weatherometer uses a carbon arc lamp as the primary irradiation source to reproduce sunlight exposure conditions. The carbon arc lamp generates a broad spectrum of artificial light, allowing manufacturers to evaluate color fading, surface degradation, and physical property changes caused by continuous light exposure.

LIB Sunshine Carbon Arc Weatherometer uses a 1500W air-cooled carbon arc lamp with an irradiance range of 100~800 W/㎡ and a wavelength measurement range of 280nm~8000nm. During testing, samples are exposed to controlled light intensity while the equipment automatically maintains stable test conditions.

The testing method follows international weathering evaluation requirements, including JIS B 7753, which specifies carbon arc apparatus operation for exposure testing of nonmetallic materials.

This method is widely used for evaluating the durability of automotive coatings and interior materials, plastic components, rubber products, outdoor equipment, and building materials. By simulating long-term exposure to sunlight, heat, and moisture, manufacturers can assess material aging performance, identify potential degradation issues, and improve product reliability before market release.

By accelerating light aging in the laboratory, manufacturers can predict long-term outdoor performance within a shorter testing period.

2. Temperature and Humidity Aging Control

Light exposure alone cannot fully represent outdoor environments. Real products experience combined effects from sunlight, temperature changes, and moisture. Therefore, Sunshine Carbon Arc Weatherometer integrates precise temperature and humidity control to reproduce complex climate conditions.

During testing, the chamber maintains precise environmental conditions, including a chamber temperature of Ambient~100℃ ±2℃, a Black Panel Temperature (BPT) of 35℃~85℃ ±2℃, and a humidity range of 50%~98% RH. The black panel temperature measurement system monitors the actual heat absorbed by the sample surface, providing a more accurate simulation of solar heating conditions during outdoor exposure.

This combined aging method helps evaluate various material performance changes, including coating adhesion loss, material discoloration, surface cracking, mechanical strength reduction, and moisture-related degradation. By reproducing the combined effects of light, heat, and humidity, the test provides reliable data for predicting long-term material durability.

Sunshine Carbon Arc Weatherometer is widely applied in industries requiring high environmental reliability, such as automotive manufacturing, electronics, paint and coating industries, new material research, and aerospace components. It helps engineers optimize material selection, improve product durability, and verify performance before products enter real-world applications.

3. Accelerated Weathering Test According to Industry Standards

Professional weathering testing requires repeatable results and compliance with recognized standards. Sunshine Carbon Arc Weatherometer is designed according to international testing requirements, helping laboratories generate reliable aging data.

The main applicable standard for Sunshine Carbon Arc Weatherometer testing is JIS B 7753, which defines the requirements for carbon arc weathering test equipment, including light exposure methods and testing procedures for nonmetallic materials. During a typical test process, samples are installed on the rotating sample holder, while the carbon arc lamp generates artificial sunlight exposure. The chamber then adjusts temperature and humidity conditions according to the programmed testing profile to simulate outdoor aging environments. After accelerated exposure, material changes are evaluated to determine durability performance.

The Sunshine Carbon Arc Weatherometer is widely used for new material selection, existing material improvement, quality control verification, and durability comparison testing. With a programmable controller and diagnostic message display, operators can easily monitor test conditions, identify potential issues, and maintain stable and repeatable testing accuracy throughout the aging process.

A motorcycle manufacturer in India selected LIB Sunshine Carbon Arc Weatherometer for material performance evaluation. The customer needed reliable equipment to test motorcycle components under simulated sunlight, heat, and humidity conditions before final production.

After testing, the customer highly recognized LIB equipment for its:

Both Sunshine Carbon Arc Weatherometer and Sunshine Xenon Arc Weatherometer are widely used for accelerated weathering tests. However, they use different light sources and are designed for different testing purposes.

Choosing the right equipment depends on the material type, required standard, testing environment, and expected aging simulation.

Comparison Between Sunshine Carbon Arc Weatherometer and Sunshine Xenon Arc Weatherometer

For example, ASTM D6695 and ISO 11341 define xenon arc exposure requirements, including irradiance control, black panel temperature, water spray cycles, and humidity conditions for coating durability evaluation.

ASTM G155 specifies accelerated weathering procedures using xenon arc lamps combined with light, water spray, darkness, and humidity cycles.

ASTM D7869 focuses on high-temperature and high-humidity weather resistance testing, especially for coatings exposed to transportation and outdoor environments.

How to Select the Right Weatherometer?

Before purchasing weathering test equipment, manufacturers should consider:

1. Testing Standards

If your products must comply with specific standards, select equipment based on required testing methods.

JIS B 7753 → Sunshine Carbon Arc Weatherometer

ASTM G155 / ISO 11341 → Xenon Arc Weatherometer

2. Material Type

Different materials respond differently to artificial sunlight exposure, so selecting the right weathering test method is essential for accurate durability evaluation. Carbon arc testing is suitable for materials such as plastics, general coatings, and rubber products, providing an effective solution for evaluating light resistance and aging performance. In comparison, xenon testing is preferred for applications requiring more realistic sunlight simulation, including automotive paints, high-performance coatings, and outdoor products exposed to natural sunlight. By selecting the appropriate weathering method, manufacturers can obtain more reliable aging data and improve material performance before market application

3. Testing Accuracy Requirements

For basic durability comparison, carbon arc testing provides an economical solution.

For precise sunlight reproduction and certification testing, xenon weatherometers provide higher simulation accuracy.

LIB provides both carbon arc and xenon arc weathering solutions to help customers select suitable equipment according to their testing goals.
