Foreword

This document was drafted in accordance with the rules given in GB/T 1.1-2020 "Directives for standardization - Part 1.Rules for the structure and drafting of standardizing documents". This document is Part 3 of GB/T 1844 "Plastics - Symbols and abbreviated terms". The following parts of GB/T 1844 have been issued. - Part 1.Basic polymers and their special characteristics; - Part 2.Fillers and reinforcing materials; - Part 3.Plasticizers; - Part 4.Tables of hardness values. This document replaces GB/T 1844.3-2008 "Plastics - Symbols and abbreviated terms - Part 3.Plasticizers". Compared with GB/T 1844.3-2008, in addition to the structural adjustments and editorial modifications, the main technical changes in this document are as follows. a) Change "Annex A provides the symbols for the various components of the abbreviated term" to " Annex A specifies the symbols for the various components of the abbreviated term" (see 4.4 of this Edition; 2.4 of Edition version); b) Add abbreviated terms ATBC, ATEC, ATEHC, DBTP, DINCH and DPHP (see Table 1 of this Edition); c) Add the abbreviated terms DPGDB and ODTM to CAS-RN (see Table 1 of this Edition); d) Change CAS-RN of abbreviated terms DOZ, TCEF, and TOTM (see Table 1 of this Edition; Table 1 of Edition 2008); e) Add DPCP as an abbreviated term for diphenyloctyl phosphate, DPOP for diphenyloctyl phosphate, ATBC for acetyl tributyl citrate, TCEP for trichloroethyl phosphate, TCP for tricresyl phosphate, ATEC for acetyl triethyl citrate, TOP for trioctyl phosphate, and TXP for trixylyl phosphate (see Table 1 of this Edition); f) Change the abbreviated term of epoxidized soybean oil from ESO to ESBO (see Table 1 of this Edition; Table 1 of Edition 2008); g) Change the IUPAC name of ODP. Add 119-07-3 as its CAS-RN (see Table 1 of this Edition; Table 1 of Edition 2008); h) Change the IUPAC names of TBAC and TEAC (see Table 1 of this Edition; Table 1 of Edition 2008); i) Change the symbol for soybeans from "S" to "SB" (see Annex A of this Edition; Annex A of Edition 2008); j) Delete the symbol "PM" (see Annex A of Edition 2008); k) Add "F" as the symbol for phosphate esters (see Annex A of this Edition). The modification of this document uses ISO 1043-3.2016 "Plastics - Symbols and abbreviated terms - Part 3.Plasticizers". The technical differences between this document and ISO 1043-3.2016 and their reasons are as follows. a) In Clause 1, add the content of "applicable limits" to comply with the provisions of GB/T 1.1-2020; b) Replace ISO 1043-1 (see Clause 3) with GB/T 1844.1, which modified ISO 1043- 1, to adapt to the technical conditions in China; c) Replace ISO 472 (see Clause 3) with GB/T 2035, which is equivalent to ISO 472, to adapt to the technical conditions in China; d) Add CAS-RN of BNP and PPA to Table 1 to adapt to the technical conditions in China.
