Abstract

Introduction

Proper protective gear sizing is an important factor both for civilian and defence population. This is much more so in the defence sector as a well fitted personal protective ensemble (PPE), for example, a bullet proof jacket could be the difference between survival and fatality. So in order to develop a size reference for personal protective ensemble, a pan India anthropometric study was planned and carried out on Indian defence male personnel from various locations.

Materials and methods

Between 2016 and 17, the research team carried out an anthropometric survey of male Indian soldiers (n = 2281), posted in different parts of the country whose age ranged from 21 to 50 years. Descriptive analysis of the volunteers was carried out using Statistical Product and Service Solution (SPSS) v. 21. Principle component and cluster analysis was carried out for clustering them into various categories. Chest circumference is taken as the main component for the upper protective gear sizing and hip circumference is considered for lower protective gear sizing.

Results

Three sizes were developed for Upper Personal Protective Ensemble (UPPE) using chest girth as the main measurement and corresponding three size ranges for the Lower Personal Protective Ensemble (LPPE) using belt girth as the main measurement, with size range intervals of 4 cm and 6 cm. Other parameters included were arm length, neck to wrist length, inter acromion length, circumference at deltoid for upper ensemble; stomach girth, natural waist height and hip girth for lower ensemble.

Conclusion

Using the system of cluster analysis, three major sizes were developed namely Small, Medium and Large for both Upper and Lower Personal Protective Ensembles. Small size was further divided into XXS, XS, S and Large was further divided into L, XL, XXL and XXXL so as to have maximum coverage.

基于3D全身人体扫描的印度男性国防人员个人防护套装参考尺码开发

摘要

介绍

适当的防护装备尺寸是平民和国防人员的重要因素。在国防领域，这是一件非常合适的个人防护装束（PPE），例如，防弹外套可能是生存与死亡之间的区别。因此，为了开发个人防护服的尺寸参考，计划并针对来自各地的印度国防男性人员进行了泛印度人体测量研究。

材料和方法

在2016年至17日之间，研究小组对印度印第安男性士兵（n  = 2281）进行了人体测量学调查，其年龄分布在21至50岁之间。使用统计产品和服务解决方案（SPSS）v。21对志愿者进行描述性分析，并进行了主成分分析和聚类分析，将其分为不同类别。胸围被用作上护具尺寸的主要组成部分，而髋围被视为下护具尺寸的主要组成部分。

结果

使用腰围作为主要尺寸的上个人防护装束（UPPE）开发了三种尺寸，以皮带围为主要尺寸的下个人防护装束（LPPE）开发了相应的三种尺寸范围，尺寸范围分别为4 cm和6厘米。其他参数包括手臂长度，脖子到腕部的长度，肩峰间长度，上三角肌的三角肌周长；胃围，自然腰高和臀围可降低整体合奏。

结论

使用聚类分析系统，开发了三种主要尺寸，分别是上个人防护套装和下个人防护套装的小型，中型和大型。小尺寸进一步分为XXS，XS，S，大尺寸进一步分为L，XL，XXL和XXXL，以实现最大覆盖。
