Introduction

This section is a standard method on flexural testing machine model evaluation, according JJF 1016-2009 "Measuring Instruments type Assessment outline guidelines for the preparation of formula ", JJF 1015-2002" Measuring Instruments type evaluation and type approval of general norms " Claims, with reference to the content of GB/T 2611-2007 "General technical requirements for the test machine", JB/T 9370-1999 "anti-Off test machine technical conditions ", JC/T 724-2005" Cement electric bending test machine ", JJG476-2001 "Flexural testing machine" and other standards and procedures required when compiled.

This outline is given a basic outline of the required test conditions, test equipment evaluation bending test machine performance meets and test methods. As long as the measurement uncertainty of the syllabus to meet the requirements, but also use other test equipment.

Bending test machine such as the ability to express or technical indicators higher than the outline requirements to (required) in accordance with corporate standards, instructions Books and other technical documents prepared outline additional provisions, higher flexural testing machine verification outline requirements of technical indicators.

Flexural testing machine model evaluation outline

1 Scope

This outline is applied to non-metallic sheet bending test machine (cement mortar) electric bending testing machine, digital anti-ceramics Fold testing machine (hereinafter referred to as bending machine) type evaluation.

3 Overview

3.1 Purpose

Flexural testing machine is mainly used in measuring mechanical properties of materials and bending of manufactured goods. Against different materials or finished products Flexural testing machine fold test used may be different, such as electric bending testing machine is mainly measured rectangular cement mortar test Like bending strength.

3.2 Principle structure Flexural testing machine can have a variety of structural forms, such as leveraged, superposition, etc., but required a strong level measuring device, Biasing means and the holding means of the sample.
