Introduction

"Static uniaxial testing machine model evaluation outline" framework reference the corresponding test machine state standards and inspection Set procedure consists of the following three parts.

1.JJF 1296.1-2011 of static uniaxial testing machine model evaluation framework - Part 1. electronic universal test Testing machine 2.JJF 1296.2-2011 of static uniaxial testing machine model evaluation framework - Part 2. hydraulic servo universal test Testing machine 3.JJF 1296.3-2011 of static uniaxial testing machine model evaluation framework - Part 3. Hydraulic universal test Testing machine when you use this syllabus for type evaluation test of static uniaxial testing machines, test should be based on the type of machine selection Outline the appropriate section.

This part is the content on hydraulic servo universal testing machine model evaluation, according JJF 1016-2009 "Meter A pattern evaluation outline guidelines for the preparation ", JJF 1015-2002" Measuring Instruments type evaluation and type approval of universal norms " Requirements, according to the national standard GB/T 16826-2008 "electro-hydraulic servo universal testing machine" and the national metrology regulations Cheng JJG139-1999 "tension, pressure, and universal testing machine" and compiled. Since the classification test machine than Much more complicated patterns, such as the use of the syllabus for type evaluation test, the test does not completely cover the entire machine to be measured when summing technical requirements, technical documentation enterprise standards, brochures, etc. should refer to the additional provisions related to the preparation of the outline as Based on type evaluation tests.

Static uniaxial testing machine model evaluation outline Part 2. electro-hydraulic servo universal testing machine

1 Scope

This outline is applied to evaluate the type of electro-hydraulic servo universal testing machine. Electro-hydraulic servo force (or pressure) testing machine Type evaluation can refer to this outline.
