Foreword

GB/T 22108 in the "pneumatic compressed air filters," the general title, includes the following components.

--- Part 1. Key Features and Product Identification business documents contained in the request;

--- Part 2. Test method for assessing the main characteristics of business contained in the file.

This part of GB/T 22108 Part 2.

This part identical with ISO 5782-2:1997 "Pneumatic Compressed air filters - Part 2. Evaluation of business documents contained the main characteristics of the test method "(in English) this section is equivalent translation ISO 5782-2:1997, for ease of use, this section made the following editorial changes.

--- In the "Normative references" to the referenced section consistent with the technical content of relevant international standards replace national standards international standard.

Since the implementation of this standard, JB/T 7374-1994 "pneumatic air filter technology" obsolete.

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee of hydraulic and pneumatic (SAC/TC3) centralized.

Introduction

In the pneumatic system, the power is through a closed loop control and compressed air to pass. When asked mechanically compressed air through when the filter, air filter element is to remove solid and liquid contaminants and design.

GB/T 22108.2-2008/ISO 5782-2:1997 Pneumatic compressed air filters Part 2. Evaluation of business contained in the file the main characteristics of the test method

1 Scope

This section GB/T 22108 specifies the main features according to GB/T 22108.1 pneumatic compressed air filters in the business contained in the file of test items for testing, test equipment, test procedures and test results reporting methods.

The purpose of this section is.

--- The test methods and test data representation standardized, so that the performance comparison pneumatic air filter is simple;

--- Helps in the pneumatic system for the rational use of pneumatic compression filter.

Specified in this test program was to air between different types of compressed air filters comparison, and not for each Filters are manufactured for production test.
