Introduction:
When evaluating transparent or translucent materials like plastic films, packaging, and glass, clarity is everything. But clarity is not just about what the eye sees—it’s about scientifically quantifying how much light passes through and how much gets scattered. This is where haze meters come in. For results to be trusted worldwide, haze meters must comply with recognized international standards.
Our haze meter is fully compliant with major global standards including ASTM, ISO, GB/T, JIS, and CIE. Let’s break down what each standard means and why it matters.
1. ASTM D1003 / D1044
These are widely recognized in North America. ASTM D1003 defines the standard test methods for haze and luminous transmittance of transparent plastics while ASTM D1044 defines the test methods for resistance of transparent plastics to surface abrasion (which can increase haze).
2. ISO Standards (13468 & 14782)
ISO standards are globally accepted, providing methods for measurement of luminous transmittance for transparent plastics using integrating sphere methods (ISO 13468) and measurement of haze in transparent plastics (ISO 14782). They are especially critical for industries like glass, plastic films, where precision and consistency are non-negotiable.
3. GB/T & JJF Standards (China)
China’s GB/T 2410 is equivalent to ASTM and ISO methods but adapted for national use. JJF 1303-2011 defines the metrological and technical requirements haze meters must meet, ensuring reliability in quality control across industries.
4. CIE 15.2 Standard
The CIE (International Commission on Illumination) is the global authority on light and color. Its 15.2 standard provides the foundation for accurate optical measurements, ensuring that haze data aligns with human visual perception.
5. JIS Standards (Japan: K7105, K7361, K7136)
Japan’s industrial standards define rigorous methods for haze and transmittance measurement. They are widely followed by Japanese manufacturers and trusted globally, ensuring harmonization with international trade requirements.
Conclusion:
Compliance with multiple international standards ensures that haze measurements are consistent, accurate, and universally accepted. Whether your products are sold in the US, Europe, Japan, or China, our haze meter provides reliable results that meet every region’s quality benchmarks.
