This section GB/T 15670 Part 23.
This section drafted in accordance with GB/T 1.1-2009 given rules.
Part of this section instead of GB/T 15670-1995 "pesticide registration toxicology test methods."
This section and GB/T 15670-1995 teratogenic test section compared to the main changes are as follows.
--- Modify and adjust the standard of the overall structure and layout format;
--- Added some sections (see Chapter 1, Chapter 2, Chapter 3, Chapter 5, Chapter 6, 7.1 and Chapter 9);
--- Modify the requirements of experimental animals (see 7.2,.1995 edition of 15.3);
--- Modified dose and grouping (see 7.3,.1995 version 15.5);
--- In the body surface, visceral and skeletal items, the examination item list is deleted (see 7.4.4.2, 7.4.4.3 and 7.4.4.4.1995
Version 15.9.3 and 15.9.4);
--- Visceral and skeletal observation, an increase of the observation program, bone staining methods and rabbit visceral observation and bone observation content (see
7.4.4.3 and 7.4.4.4.4,.1995 edition 15.9.4).

The following terms and definitions apply to this document.
3.1
Teratogenicity
The characteristics of chemicals that cause permanent structural and functional abnormalities in offspring during embryonic development.
3.2
Maternal toxicity
Cause direct or indirect effects of health damage on the parent female pregnancy animal.
