Foreword

This standard is identical with ISO 7458.2004 "in a glass container pressure resistance test method" (in English). This standard is based on ISO 7458.2004 re-drafted. This standard and ISO 7458.2004 for the difference. --- Remove the ISO 7458.2004 Preamble. --- Increasing the preface of this standard. This standard replaces 4546-1998 "Glass containers - Internal pressure resistance test method" GB/T . This standard and GB/T 4546-1998 difference is. --- Increased this standard directory. Pressurization rate --- Method B from 0.4MPa/s ± 0.1MPa/s (4bar/s ± 1bar/s) up to 0.58MPa/s ± 0.1MPa/s (5.8bar/s ± 1bar/s). --- Increase the safety device requirements. 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, Sang Yi, Zhang . This standard replaces the standards previously issued as follows. --- GB/T 4546-1984; GB/T 4546-1998. GB/T 4546-2008/ISO 7458.2004 Internal pressure resistance - Test method for glass containers

1 Scope

This standard specifies two test methods for the determination of pressure-resistant glass container. A method of applying a constant internal pressure is within a predetermined time Test Method B is to increase the force of internal pressure at a predetermined constant rate tests. This standard applies to pressure resistant glass container in the test.

2 Sampling

Shall predetermined number of glass test vessel. Can not withstand the inner pressure resistance test results of any other test mechanical and thermal properties of glass container test before the test.

3 Test Method

Test medium is water. 3.1 Method A 3.1.1 Overview Test constant internal pressure is applied within a predetermined period of time. 3.1.2 Equipment This equipment should meet the following requirements. a) test should be clamped glass container finish and hung tested. b) at the time of the test, in order to keep the pressurized medium, should be flexible seal between the indenter and the sealing surface. c) there should be means reaches a predetermined fluid pressure value, the initial pressurization rate of 1.0MPa/s ± 0.2MPa/s (10bar/s ± 2bar/s) and to keep the pressure constant during the test. 3.1.3 Step 3.1.3.1 the sample to reach room temperature and then poured into the room temperature difference of ± 5 ℃ water, prior to testing in order to avoid the introduction of additional pressure. 3.1.3.2 use any of the following test methods for the purposes of the test. a) by test Test the internal pressure reaches a predetermined value, and to maintain constant pressure 60s ± 2s or different durations, but the device should be corrected pressure The method of equivalent value can be obtained 60s constant test results. b) incremental test Following the a) test, in increasing the amount of 0.1MPa or 0.2MPa (1bar or 2bar) supercharging pressure value until the glass Container glass breakage rate of 50% or 100%. 3.1.3.3 Test Report The test report shall include the following. a) the implementation of standards. b) sample size and sampling methods. c) the number of samples taken from each mold only. d) the type of test methods, namely through tests 5.1.3.2a) or incremental test 5.1.3.2b). e) Test results. 1) Press 5.1.3.2a) carried out by the test. Pressure vessels and the number of glass used in the experiment and the corresponding burst pressure of the rupture. GB/T 4546-2008/ISO 7458.2004
