YY/T 0699-2008Clothing for protection against liquid chemicals - Determination of the resistance of protective clothing materials to penetration by liquids under pressure (English PDF)

Foreword

This standard is identical with ISO 13994:1998 "liquid chemicals protective equipment Protective clothing material liquid penetration resistance to compression performance test method".

For ease of use, this standard made the following editorial changes. "This International Standard" be replaced by "this standard";

With a decimal point instead of a comma as the decimal point, ""; By deleting the preface to international standards.

Introduction

Production, use and transport of liquid chemicals staff easy access to the human body may cause contact damage liquid. These injuries May cause acute injury (such as skin irritation and burns) or chronic diseases (such as cancer). Since engineering controls can not eliminate all of the contact Energy, people will focus on using anti-infiltration and anti-penetration and anti-aging protective clothing to minimize direct contact with skin.

This test method is only used to test the anti-pressurized liquid penetration. Anti-infiltration and anti-aging and anti-stress-test its performance liquid permeation His methods.

1 Scope

This standard specifies the determination of continuous contact with the liquid under pressure for laboratory, protective clothing such as repeated exposure to pressurized spray and splash Liquids, protective clothing material - Test methods liquid penetration resistance. Protective clothing "pass/fail" conclusion to the case of visual liquid penetration determine.

This test method is usually used to evaluate the protective clothing materials and sample material from the finished protective clothing protective effect.

Note: Finished protective clothing including gloves, sleeves, aprons, clothes, scarves, boots and so on. "Product sample" includes both an integral part of the finished protective clothing, also includes seam Combined Department and other discrete parts.

This test can be used to determine the protective clothing materials and structures in different environments restriction of hazardous liquid chemical exposure. The micro test Ability to determine the fabric anti-hole liquid is particularly effective.

Penetration test qualified, but the sample may occur substantial material penetration. Penetrate more sensitive analysis should be carried out ISO 6529.

When using a lower test conditions when no liquid pressure, anti-penetration test material according to ISO 6530 carried out. ISO 6530 with a relative Small capacity liquid liquid short-term challenges, such a test is suitable for processing, and other non-porous film substrate or uncoated materials.

This standard describes only for protective clothing material or some material structures (such as stapling) performance. It does not involve the design, the overall structure and composition, Or interface, or other factors that may affect the overall protective effect of protective clothing clothing.

In particular, this standard does not have to simulate the possible exposure of protective clothing when practical use. Test data due to restrictions by the material, The need for extensive comparative assessment of their anti-liquid penetration properties.
