Introduction

This standard specifies the use of special testing machine in the laboratory to determine the portable chain saw (hereinafter referred to as the chain saw) sawing efficiency and sawing fuel consumption Consumption rate of the method, the test accuracy depends mainly on the testing machine and test instrument accuracy, by the operator of human factors less affected. Determination of chain saws Sawing efficiency and sawing fuel consumption of another method is LY/T 1198-1996 "saws sawing test method simple method" rules Set the manual operation plus stopwatch timing method. Manual operation by the impact of human factors, the test accuracy is low. But LY/T 1198 regulations The test method is simple and can be used for outdoor or forest field testing. Portable saw blade sawing efficiency and fuel consumption rate Test method engineering method

1 Scope

This standard specifies the use of special testing machine to measure the efficiency of sawing saws and sawing fuel consumption rate of the method. This standard applies to the use of standard test cases when the oil saw.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document.

3 terms and definitions

The following definitions and definitions as defined in GB/T 18960 apply to this document. 3.1 Into the effortless downwardforceusedinsawing The test system applies the lower pressure on the test piece by the chain saw.

4 test conditions

4.1 Test environment conditions When the environmental parameter αa satisfies the condition of 0.93≤αa≤1.07, it is considered that the test is effective. The environmental parameter αa is calculated according to formula (1) αa = py-φypsy 1.2 Ty 0.6 (1) Where. αa --- environmental parameters; py - total pressure in kPa (kPa); φy --- relative humidity; psy --- test environment saturated steam pressure, the unit is kPa (kPa); Ty - the absolute temperature of the air in the test environment, in Kelvin (K). When measuring, the allowable error of ambient temperature is ± 2K, the allowable error of atmospheric pressure is ± 0.1kPa, and the allowable error of relative humidity is ± 3% (absolute). 4.2 Test Saw 4.2.1 Test saws should be fully assembled, according to the standard production, the inspection of qualified products. ......
