This standard is equivalent to the properties of borosilicate glass 3.3 of IS03585-1991. All performance indicators and test methods are equivalent to the provisions of this international standard, and this standard has not made any deletions or changes. According to the provisions of GB/T1.1-1993, only editorial changes were made. For ISO standards cited in the standards that have been formulated into Chinese standards, the numbers and names of Chinese standards shall be adopted. If the referenced standard has not been formulated as a national standard, the original standard shall be directly quoted according to relevant regulations. This standard is equivalent to the international standard. Appendix A of the referenced standard is a reminder. This standard is drafted by China National Chemical Equipment Corporation. This standard is drafted by the National Non-metallic Chemical Equipment Corporation. The main organizers of this standard are: Shen Changzhi, Chengdu Hongliu Jiajun, He Xiang. HG/T3115—1998 ISO (International Organization for Standardization) is a worldwide organization of national standards associations (ISO member bodies). The work of preparing International Standards is carried out through ISO technical committees. Any member body interested in a subject for which a technical committee has been established has the right to serve on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC). Draft International Standards adopted by the technical committees are circulated to the member bodies for publication. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Drafted by the International Standards Committee.
