Professional Sun Protection (Anti UV) Uniform Solutions by Dragon Uniform Pte Ltd: A Comprehensive Analysis Based on ISO 24443:2021 Standards 

Industry Background and Standard Overview

Singapore's equatorial location results in consistently "High" to "Extreme" UV Index levels (average UVI 8-12) year-round, making sun-protective uniforms essential for outdoor workers. The ISO 24443:2021 standard serves as the authoritative international benchmark for evaluating UVA protection in sun care products, providing scientifically rigorous testing methodologies for the uniform industry.

​​Key Updates in the Standard​​:

· Acceptance of both molded HD6 and sandblasted SB6 PMMA test substrates

· Adjusted application quantity for sandblasted plates to 1.2mg/cm² (±1.5%)

· Introduction of UVA protection factor standard P8 (average UVA-PF 19.1)

· New critical wavelength calculation requirement

· Adjusted SPF correction coefficient C range to 0.6-1.6

· Maximum UVA radiation dose limited to 36 J/cm²

Technical Testing Requirements

Equipment and Material Specifications

Key Testing Process Parameters

​​Sample Application Specifications​​:

· Molded substrate (HD6): 1.3mg/cm² (±1.6%)

· Sandblasted substrate (SB6): 1.2mg/cm² (±1.5%)
