Foreword

YY/T 0616 `` Disposable Medical Gloves '' is intended to be divided into the following parts.

--- Part 1. Biological evaluation requirements and tests;

--- Part 2. Requirements and tests for determining shelf life;

--- Part 3. Method for determining the actual time expiry date with the finished gloves in storage;

--- Part 4. Puncture resistance test method;

--- Part 5. Test method for continuous exposure to chemical penetration; This part is Part 5 of YY/T 0616.

This section is drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

Medical workers may be exposed to chemicals that are harmful to healthy people at work (such as various disinfectants, chemical sterilants, Chemicals, etc.), causing various levels of harm to the human body, such as acute trauma such as skin irritation and burns, and chronic diseases such as cancer Variant disease. To avoid such hazards, medical personnel need to wear products with appropriate protective properties (such as medical gloves) to achieve effective The purpose of protection.

The penetration of chemicals into protective product materials usually includes two forms. penetration and permeation, both of which The mechanism is completely different. The permeation tests in this section are based on the permeation mechanism (see 4.1). Penetration is when a substance passes through the medicine at a non-molecular level Use the movement of the voids in the glove material (including joint gaps, incomplete seals, and/or holes, holes, etc. in the material itself). Needless to penetrate The state changes, that is, the solid chemical passes through the voids of the material in a solid state, the liquid passes in a liquid state, and the gas passes in a gas state.

At present, European and American countries require such protective gloves to indicate the type of protection (such as chemotherapy) or protection level (Such as level 1). A set of chemical resistance test equipment for medical gloves and a standard test method established in this section can be used to evaluate medical The resistance of gloves to liquid chemicals can better guide medical staff to choose suitable products for effective protection.

This section establishes a general test method for chemical resistance of medical glove materials.It will give a specific application, that is, determine the resistance of medical glove materials to chemotherapy. Test method for drug permeability. Single-use medical gloves. Part 5. Test method for continuous penetration resistance against chemicals

1 Scope

This part of YY/T 0616 specifies the test of resistance to the penetration of liquid chemicals by disposable medical gloves under continuous exposure Test conditions, test procedures and results report.

This section applies to the evaluation of chemical penetration resistance of disposable medical gloves.
