A Study on the Korean Fit Test Panel and Static Headform Chamber

Abstract 

Objectives: A fit test panel is needed to identify the fit performance of a respirator and its face seal. This is a criterion for selecting

subjects that can represent the facial characteristics of users. Although anthropometry data has been developed for

people in United States and China it is not yet present in Korea. This study aimed to develop a Korean fit test panel and test

headform.

Methods: For the 7th and 8th waves of the Size Korea anthropometry data, facial measurements of 11,429 people aged 15 to 69 years were used for analysis. PCA and bivariate panel were classified using the ISO16976-2:2022(E) anthropometrics

analysis method. Based on this result, a static headform was developemed and a fit test chamber was constructed.

Results: Of the 11,429 Korean people used for principal component analysis, 11,300 were included in the ellipse, marking an

acceptance rate of 98.87% on PCA panel. The face types were classified into five types. Among them, a large, medium,

and small static headform were printed using a 3D printer. In addition, 10,985 people (96.12%) were included in the

bivariate panel based on face length and face width. The y-axis (face length) boundary was 97.87 to 134.59 mm, and

the x-axis (face width) boundary was 120.75 to 158.23 mm.

Conclusions: Compared to the ISO analysis, the Korean principal component was narrower in the width item (PC1) and longer in

the length item (PC2). For the future, it is necessary to conduct a fit test using the developed headform and chamber device

to confirm the usefulness of this Korean test panel. Therefore, this study is considered valuable as basic research for

Korean test panels.
