Foreword

This revised standard adopts ISO 9008.1991 "Bolipingguan vertical axis deviation test method" (in English). This standard is based on ISO 9008.1991 re-drafted. This standard and ISO 9008.1991 for the difference. --- Remove the ISO 9008.1991 standard preamble and references; --- Increase the directory with the preface; --- Increasing the normative references and terms and definitions; --- Increased reading microscope measurement tool on the vertical columns; --- Modify the instrument in a self-centering clamping device is described. This standard replaces GB/T 8452-1987 "glass container glass bottles vertical axis deviation test methods." This standard and GB/T 8452-1987 difference is. --- Remove the GB/T 8452-1987 Definitions of terms; --- Increasing the preface of this standard; --- Increasing the normative references and terms and definitions; --- Revised instrument measuring tool in the vertical column description. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee household glass (SAC/TC377) centralized. This standard was drafted. Donghua University, the National Optical glass enamels Quality Supervision and Inspection Center. The main drafters of this standard. Dai Qi, Zhang . This standard replaces the standards previously issued as follows. --- GB/T 8452-1987. Bolipingguan vertical axis deviation test methods

1 Scope

This standard specifies the test methods Bolipingguan vertical axis deviation. This standard applies to vertical axis deviation measuring glass containers.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. GB/T 9987 Bolipingguan manufacturing term

3 Terms and Definitions

Terms and definitions GB/T 9987 established in this standard applies.

4 Requirements

4.1 Instrument requirement is to ensure that the bottom of the glass containers can be measured horizontally finish with vertical axis deviation. 4.2 Instrument of measure depends on the type of use. a) by measurements with foot level; b) or dial indicator reading microscope; c) an enlarged projection scale. 4.3 Instrument with the self-centering clamping device and swivel base with a vertical column or horizontal ruler or dial indicator readings microscope Composition, or be accompanied by a V-shaped bottom and a block with a horizontal or vertical ruler or dial indicator reading microscope column composition. Dial indicator, reading Number microscope or horizontal ruler should be able to adjust the height and horizontal position. You can also use non-contact optical scanning device. 4.4 Deviation tools should be placed on the outside edge of the bottle. 4.5 non-circular glass containers should be able to make use of instruments to measure the rotation of the holder in the center of the floor. Note. You can also use other types achieve precision instruments.

5 Sample

Should a predetermined quantity of glass containers tested. Samples should meet the requirements, severe deformation of the bottom glass containers should be removed. Step 6 6.1 Bolipingguan held horizontal rotation on the chassis, swivel base 360 \u200b\u200b°. Such as when used with the V-shaped bottom block, then the sample is close to the V On-block, 45 ° in the horizontal direction exerts a downward pressure on the sample measurement, the rotation Bolipingguan 360 °. Under the outer edge of the bottle and 6.2 recorded maximum and minimum distance between the fixed points, vertical axis deviation is the difference between the measured maximum and minimum values \u200b\u200bof half. 6.3 Measurement accuracy is 0.1mm. 6.4 amended by precision obtained from the measured vertical axis deviation.
