AN INTROSPECTION INTO THE QUALITY REQUIREMENTS, TEST

METHODS AND SAMPLING OF PLASTIC JERRY CANS

STANDARD FOR PLASTIC JERRYCANS NIS 494:2004

Definition and Brief history A portable container of a capacity

between 4 and 50 liters (inclusive) ideal for the transport and storage of low to medium-viscosity liquids.

First designed in the 1930’s for military use to hold 20 liters of fuel in Germany but was made with steel.

INTRODUCTION

Introduction Ctd.Transition from metal to plastic – resource

conservation, waste reduction and smartness

Packaging, storage, and transport of liquid industrial materials and products. E.g.: foods, chemicals, petroleum products and others

The rate of reuse, especially for domestic purposes, is even higher

USE OF JERRYCANS

To provide the initial users (first buyers) with an objective means of assessing the qualities of jerry cans and

to guide manufacturers in controlling the quality of their products.

THE NEED FOR STANDARD FOR PLASTIC JERRYCANS

Requirements and test methods for the properties of the materials

The performance characteristics of the product(s) such as: permeability impact strength and compatibility with intended contents
