In India’s diverse industrial environment, ensuring material durability under sunlight is essential for product reliability. At Krishna Metallurgical Laboratories, we offer superior UV resistance testing services using Atlas’ advanced UVTest chamber—one of the most respected and globally accepted UV simulation systems in the world.
Our UV resistance testing helps industries evaluate how materials such as plastics, rubbers, paints, coatings, textiles, and polymers perform under prolonged ultraviolet (UV) exposure, mimicking years of sun damage within days or weeks.
What is UV Resistance Testing?
UV resistance testing is a method used to simulate long-term exposure of materials to sunlight, particularly its ultraviolet radiation, to assess changes in:
- Color
- Gloss
- Texture
- Cracking
- Peeling
- Strength and elasticity
Industries use this data to make decisions about product development, warranty timelines, packaging durability, and product shelf-life under outdoor conditions.
Why UV Resistance Testing is Important for Indian Manufacturers
India’s climatic conditions, with high solar intensity in many regions, make UV degradation a major concern for materials used outdoors. If not tested, products exposed to sunlight may:
- Fade in color
- Lose surface gloss
- Become brittle and crack
- Fail prematurely in service
For sectors like automotive, construction, packaging, textiles, paints & coatings, solar, and consumer appliances, UV durability is no longer optional—it’s a critical quality requirement.
Our UV Resistance Testing Capabilities
At Krishna Metallurgical Laboratories, we’ve invested in the Atlas UVTest machine—a globally recognized and industry-preferred UV testing chamber designed to meet ASTM and ISO standards for weathering performance.
Why Atlas’ UVTest Makes Us Better:
- Precision Control: Simulates UVA or UVB wavelengths with exact irradiance, temperature, and moisture levels.
- Accelerated Testing: Replicates months or years of sunlight exposure in just days or weeks.
- Standards-Compliant: Fully compliant with international standards like ASTM G154, ISO 4892, and more.
- Water Spray Feature: Allows condensation cycles for testing weathering effects like chalking, cracking, and peeling.
- Data-Driven Output: Generates repeatable, traceable test reports ideal for audits and R&D validation.
Our lab’s use of Atlas UVTest gives our clients a competitive advantage—something rarely offered by ordinary testing providers in India.

Our UV Resistance Testing Process
We follow a structured, standards-based approach:
- Material Intake & Sample Prep
Samples are checked, documented, and conditioned before testing. - Test Cycle Design
Based on client requirements or ASTM/ISO guidelines, we select UVA/UVB wavelengths, temperatures, moisture, and exposure duration. - Exposure Simulation
Samples undergo cycles of UV exposure and condensation to simulate weathering. - Post-Test Evaluation
We assess color fading, gloss loss, surface cracking, and mechanical property changes and submit a detailed test report.
The Advantage of Precision, Speed, and Scientific Expertise
Operating under a NABL-accredited quality system, we bring scientific accuracy, advanced equipment, and a deep understanding of material behavior to every test.
Whether you’re testing for product development, compliance certification, or warranty claims, our lab provides trusted insights that support better decision-making.
