Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009 "Guidelines for Standardization Work_Part 1. Structure and Preparation of Standards"
This standard replaces JY 190-1985 "Technical Conditions for Plant Cell Models". In addition to editorial changes, the main technical changes are as follows.
-Appearance size has increased allowable tolerances;
-Added the requirement that the main parts of the model should be affixed with name or number tags;
-Specifies the materials that should and should not be used for the model;
-Specify the limit of heavy metal content in the paint of the model.
Please note that some elements of this standard may involve patents. The issuer of this standard is not responsible for identifying these patents.
This standard was proposed by the National Technical Committee for Standardization of Teaching Instruments (SAC/TC125).
This standard is under the jurisdiction of the National Technical Committee for Standardization of Teaching Instruments (SAC/TC125).
The main drafters of this standard are. Zhejiang Educational Technology Center, Ministry of Education Teaching Instrument Research Institute, Wenzhou Wuxing Industrial Co., Ltd.
The main drafters of this standard. Jiang Hui, Song Meilun, Huang Ruiqing.
This standard replaces JY 190-1985.
The standard JY 190 was first released in 1985.
