The Road to Accreditation and Certification e.g. Nano-Mark in Taiwan Analysis & Characterization 1) Ingredients? 2)Functional Performance? Generalization & Categorization of Methodology: 1)Data Base 2)Results Establishment of standard test methods Accreditation Product Certification Adaptation, Maintenance & Upgrade
NAMI’s Participation in Testing and Certification Generalization & Categorization of Methodology Establishment of standard test methods Accreditation Product Certification Adaptation, Maintenance & Upgrade NAMI Analysis & Characterization To develop new (and upgrade existing) testing methods for materials and the corresponding processing technologies To support the local S&T industry To enhance the technical competitiveness of the local labor force To gain worldwide recognition
Construction Materials Claimed to contain nanoparticles (not specified) within the coating making a non-sticking surface Functional tests: Surface roughness, hydrophobicity, hardness Material tests: Nature of nanoparticles? Size? Form?
Food Claimed to have core-shell micelles containing vitamin/protein/nutrient Functional tests: Activity and efficacy of vitamin/active ingredient? Material tests: Presence of nanoparticles / chemicals? Size? Core-shell?
Environmental Protection A 4-in-1 air filter claimed to have one layer containing “NanoSilver” and one layer having “TiO 2 nanoparticles” Claimed to be anti-bacterial and decomposes VOCs Functional tests: Anti-bacterial and photocatalytic properties Material tests: Presence of Ag and TiO 2 ? Size? Distribution?
Medical & Healthcare Products TiO 2 and ZnO nanoparticles are commonly used in sunscreens to block UV light A product claimed to contain ZnO and TiO 2 nanoparticles and offer a specified SPF Functional tests: UV absorption Material tests: Presence of nano ZnO and TiO 2 ? Size? Size distribution?
Nano Materials for Air Purification PhotocatalystCoating (1)Organic pollutant adsorbs to surface (2)Adsorbed pollutant breaks down (3)Final products: CO 2 and Water Photocatalytic Self Cleaning & Anti Bacteria Coating (TiO 2, Nano Ag) Different Supporting Media (filter element, pipe, wall etc) Air Filter, Self Cleaning & Anti Bacteria Piping, Building & Interior Surfaces
