In accordance with the requirements of the State Administration of Quality and Technical Supervision’s “Notice on the Abolition of Professional Standards and National Standards to be Transformed after Cleaning Up and Rectification” (No. 216, 1998), the Ministry of Construction has cleaned up, rectified and reviewed the national standards approved by the State Administration of Technical Supervision in 1992 for transformation into industry standards and the product standards approved and issued by the Ministry of Construction before 1992. The Ministry of Construction confirmed and issued the standard JJ83-91 "Types and dimensions of concrete conveying pipes" with the document No. 154 of Jianbiao (1999) "Notice on the Announcement of the Results of the Cleaning and Rectification of the Product Standards of the Ministry of Construction", and the new number is JG/T95-1999. In order to facilitate the implementation of the standard, only the cover, first page, and the above-margin statement of the original standard are modified accordingly, and this explanation is added and reprinted, and the original standard version is abolished at the same time.
