GB/T 3163-2024Vacuum technology - Vocabulary (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document replaces GB/T 3163-2007 "Vacuum Technology Terminology". Compared with GB/T 3163-2007, except for structural adjustment and editing, in addition to the changes in performance, the main technical changes are as follows.

--- Changed the scope of application of this document (see Chapter 1, Chapter 1 of the 2007 edition);

--- Added 70 terms such as "ultra-clean vacuum", "volume velocity" and "gas temperature" (see Chapter 3);

--- Changed 28 terms such as "vacuum area", "pressure" and "unsaturated steam" (see Chapter 3, Chapter 2, Chapter 3, 2007 Edition) Chapters 4, 5 and 6);

--- Deleted 21 terms such as "standard environmental conditions", "standard gas state" and "Pascal" (see Chapter 2 and Chapter 3 of the 2007 edition) Chapter 1, Chapter 4, Chapter 6 and Chapter 7);

--- Deleted the terms related to vacuum drying and freeze drying (see Chapter 8 of the 2007 edition);

--- Deleted the terms related to surface analysis technology (see Chapter 9 of the 2007 edition);

--- Changed the "Symbol" (see Chapter 4, Appendix B of the 2007 edition);

--- Deleted the appendix "Pressure units and conversion factors used before the adoption of the International System of Units (SI)" (see Appendix.2007 Edition).

Record A).

This document is modified to adopt ISO 3529-1:2019 "Vacuum technology vocabulary Part 1: Basic terms", ISO 3529-2:2020 "Vacuum ISO 3529-3:2014 "Vacuum technology vocabulary Part 3: Total pressure and partial pressure vacuum gauge".

Compared with ISO 3529-1:2019, ISO 3529-2:2020 and ISO 3529-3:2014, this document has many structural adjustments.

See Appendix A for a comparison of the structural number changes between the files.

This document has many technical differences compared with ISO 3529-1:2019, ISO 3529-2:2020 and ISO 3529-3:2014.

The outer margins of the clauses involved are marked with a single vertical line (|). A list of these technical differences and their reasons is given in Appendix B.

The following editorial changes were made to this document.

--- In order to coordinate with the existing standards, the name of the standard is changed to "Vacuum Technology Terminology";

--- In order to facilitate users to query the source of terms, the full text of GB/T 40344.1-2021 replaces ISO 21360-1:2012;

--- Added Appendix A (informative) "This document is combined with ISO 3529-1:2019, ISO 3529-2:2020 and ISO 3529-3:2014 "Comparison of structure numbers";

--- Added Appendix B (informative) "This document is consistent with ISO 3529-1:2019, ISO 3529-2:2020 and ISO 3529-3:2014 Technical Technical differences and reasons";

---Added index for easy reference.
