Sun Protection Factor Tester(UV proof tester)

The Sun Protection Factor (SPF) Tester, also known as a UV Proof Tester, is designed to evaluate the ultraviolet protection capabilities of sunscreens, UV-resistant fabrics, and other UV-protective materials. The instrument provides precise measurement of SPF, UPF, and UVA/UVB protection factors, offering reliable data for R&D, quality control, and regulatory compliance in cosmetic and textile industries.

Application

(1) Measurement of SPF (Sun Protection Factor) for sunscreen products.

(2) Evaluation of UPF (Ultraviolet Protection Factor) in textiles, clothing, and films.

(3) Testing of functional sunscreen additives and UV-blocking coatings.

(4) Quality control in sunscreen production lines and cosmetic manufacturing.

(5) R&D laboratories for formulation optimization of sunscreens and UV-protective materials.

(6) Testing UV performance of textiles, fabrics, and functional materials in apparel and outdoor products.

(7) Assessment of UV stability and protection for photographic emulsions, films, and packaging materials.

Standards

(1) ISO 24444 – Determination of SPF in vivo.

(2) ISO 24443 – In vitro determination of UVA protection of sunscreen products.

(3) AS/NZS 4399 – Sun protective clothing evaluation (Australia/New Zealand standard).

(4) AATCC 183 – UV transmission of textile fabrics.

(5) FDA Sunscreen Monograph – US regulatory standard for SPF testing.

(6) COLIPA in-vitro method – UVA-PF / SPF ratio determination (EU labeling).

(7) Critical Wavelength (EU and FDA labeling) – Measures UVA coverage.

(8) ISO 2442 – Test method for sunscreen protection in vitro.

(9) Australian TNUV standards – Textile UV testing protocol.

(10) UVA/UVB Protective Factor calculations – International methodology for UV evaluation.

Features

(1) Accurate Measurement – High-precision evaluation of SPF, UPF, and UVA/UVB protection metrics.

(2) Rapid Detection – Fast spectral scanning reduces test time compared with traditional in vivo or chemical methods.

(3) Multi-Scenario Application – Compatible with sunscreens, textiles, films, and functional UV materials.

(4) Objective In Vitro Testing – Provides reproducible spectral data, minimizing variability.

(5) Non-Destructive – Preserves sample integrity, particularly for textile and film specimens.

(6) Regulatory Compliance – Supports global standards and testing protocols for international markets.

(7) Automation & Data Processing – Automatic scanning, analysis, graph generation, and report printing.
