Foreword

All the technical contents of this standard are mandatory. This standard replaces GB 14193-1993 “Rules for filling of liquefied gas cylinders”. As compared with GB 14193-1993, the main differences of this standard are as follows. - MODIFY the standard structures in accordance with GB/T 1.1-2000; - ADD the filling factor of some liquefied gas (including high pressure liquefied gas and low pressure liquefied gas); - ADD that this standard does not apply to the filling of liquefied petroleum gas cylinders for motor vehicles. Appendix A to this standard is an informative appendix. This standard was proposed by AND shall be under the jurisdiction of the National Gas Standardization Technical Committee (SAC/TC 31). The drafting organizations of this standard. Capital University of Economics and Environmental Engineering, Beijing Praxair Practical Gas Co., Ltd. The main drafters of this standard. Wu Yueqian, Hao Cheng, Song Lansheng. This Standard replaces the standard previously issued as follows. - GB 14193-1993. Rules for filling of liquefied gas cylinders

1 Scope

This standard specifies the basic principles and safety technical requirements for the filling of liquefied gas cylinders (hereinafter referred to as cylinders). This standard applies to the filling of the high pressure liquefied gas cylinders and the low pressure liquefied gas cylinders for which the saturated vapor pressure at the maximum using temperature is not less than 0.1 MPa (gauge pressure, same as below). This standard does not apply to the filling of liquefied petroleum gas cylinders for motor vehicles.

2 Normative references

The provisions in following documents become the provisions of this Standard through reference in this Standard. For the dated references, the subsequent amendments (excluding corrections) or revisions do not apply to this Standard; however, parties who reach an agreement based on this Standard are encouraged to study if the latest versions of these documents are applicable. For undated references, the latest edition of the referenced document applies. GB 7144 Colored cylinder mark for gases GB/T 13005 Terminology of gas cylinders GB 15383 Connection types and dimensions for gas cylinder valve outlets

3 Terms and definitions

The terms and definitions as established in GB/T 13005 AND the following terms and definitions apply to this standard. 3.1 Filling ratio It refers to the mass of the liquefied gas which is filled in the unit volume of the cylinder.

4 Inspection and handling before filling

4.1 The filling operator shall be familiar with the characteristics of the filled media (inflammability, poison and corrosion), safety precautions and their compatibility with the cylinder material (including cylinders and such accessories as cylinder valves). 4.2 The characteristics of commonly used liquefied gas and its compatibility with metal materials can refer to Appendix A. 4.3 The gas cylinder shall be under the custody of the special person before being filled, checked one by one, AND the checking items include at least the followings. 4.4 The gas cylinders with one of the following conditions are prohibited from filling. 4.5 As for the gas cylinders for which the color or other markings and the cylinder valve outlet thread are inconsistent with those as specified for the filled gas, except for rejecting filling, it shall also check out the reasons AND report to the higher authorities and local quality supervision departments, for handling. 4.6 As for the gas cylinders which have no residual pressure, it shall remove the valve before filling to perform internal inspection to ensure that there is no foreign matter in the cylinder; AND it can only be filled after being treated in accordance with the requirements of clause 4.7. 4.9 As for the gas cylinders imported AND the gas cylinder used on the foreign aircraft, trains and ships, if they are required to be filled in our country, it shall be inspected by the inspection institute as approved or designated by the quality supervision institute. 4.10 The gas cylinders failing to pass the inspection (including those to be treated) shall be separated from the qualified gas cylinders AND clearly identified, in order to avoid misuse.

5 Filling

5.1 The filling metering device shall be kept accurate AND its maximum weighing value shall neither exceed 3 times of the actual mass of the gas cylinder (including the mass of the cylinder and the filling liquid) nor less than 1.5 times. 5.2 It is prohibited for filling when the oxygen content in the inflammable liquefied gas is more than 2% (volume fraction). 5.3 When the gas cylinder is being filled with the liquefied gases, it must strictly follow the requirements below. 5.4 Low pressure liquefied gas filling factor shall be determined in accordance with the following principles. 5.5 The filling factor of commonly used low pressure liquefied gas shall not be greater than those as specified in Table 1. The filling factor of other low pressure liquefied gas shall not be greater than the value determined by formula (1). 5.8 The liquefied gas filling volume must be accurately measured, AND checked one by one in accordance with the following requirements. 5.9 It is forbidden to determine the filling amount in the following ways. 5.10 The liquefied gas filling amount must be strictly controlled, AND if any cylinders are found of over-filling, it must appropriately drain out the over-filled liquid. 5.11 After filling the cylinder, the filling unit must attach the warning sign and the filling sign which comply with the requirements of the national standard GB 16804 onto the gas cylinders in accordance with the requirements.

6 Filling records

6.1 The filling unit shall arrange a special person to be responsible for filling the cylinder filling records. The contents of the record shall include at least the filling date, cylinder number, room temperature, cylinder indicated volume, mass, total mass after filling, presence or absence of abnormal conditions, filling operator, and inspector code.
