YY/T 0108-2008Testing methods for M-mode of ultrasonic diagnostic equipment (English PDF)

Foreword

This standard replaces YY 0108-1993 "M-mode pulse reflection ultrasound diagnostic equipment." This standard YY 0108-1993 compared to major changes are as follows.

--- YY 0108-1993 mandatory product standards, the new revised standard is the recommended test method standards;

--- Deleted all references to the technical content of product standards, including environmental testing requirements, safety requirements, appearance requirements;

--- Remove the "inspection rules" chapter;

--- Deleted "logo, packaging, transportation and storage" chapter;

--- Increase the Chapter 4, "test conditions";

--- Part in the pilot project, delete the words "comprehensive sensitivity", "linear scan", "detection blind spots" three indicators, an increase of "distance display Error "and" Show time error "two indicators;

--- In the Test Methods section, delete all test methods involve open the device under test, reconnect the circuit under test. Using not split Machines, test method does not re-wiring.

1 Scope
