Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction

Natural rubber is one of the many excellent properties materials for the manufacture of specialized

medical devices, household utensils and equipment in the industry. Water-resistance, insulation,

plasticity, elasticity and environment make products from rubber trees have a lot of benefits. However,

one component that exists in latex is the protein that has been shown to be the main cause of unwanted

effects.

The allergy to natural rubber latex proteins is a significant occupational health hazard. Natural rubber

products with high protein content can cause skin allergies when used in contact with humans, in

addition to pre
