Foreword
This standard is identical with ISO 171. 1980 "Determination of the plastic molding material --- coefficient of volume" (in English).
This standard is equivalent translation ISO 171. 1980, the same technical content.
To facilitate the use of ISO 171. 1980 made the following editorial changes.
--- The "this International Standard" by "this standard";
--- Remove the ISO 171 foreword, preface to increase the national standards;
--- The "normative references" in a chapter of an international standard with the national standards adopted in place of the file, delete the ISO 554.
1976 "for conditioning and/or testing standards of environmental norms";
--- Chapter 4, "the apparent density and density calculations required volume factor should be measured at the same temperature ISO 554 stipulated" to
"The apparent density and the density coefficient to calculate the volume required to be measured at the same temperature";
--- Chapter 6 plus "test results taken two significant figures."
This standard replaces GB/T 8324-1987 "Test Method for molding plastic volume factor."
This standard and GB/T 8324-1987 The main differences are as follows.
--- Change the standard name, increasing the foreword;
--- Increase the scope, normative references, test temperature.
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee of plastic products and plastic resins General Methods Chapter (SAC/TC15/SC4) centralized.
This standard is drafted by. National Quality Supervision and Inspection Center of synthetic resin.
Participated in the drafting of this standard. Beijing Yanshan Petrochemical resin, Sinopec hospital north of the National Chemical Building Materials Testing Center (Materials Testing
Section), National Plastic Products Quality Inspection Center (Fuzhou), blond Technology Co., Ltd. in Guangzhou.
The main drafters of this standard. Song Guirong, Wang Jiandong, Chen is willing, Ningkai Jun, Ding Jinhai, Ho Bo.
This standard was first published in 1987.
GB/T 8324-2008/ISO 171. 1980
Determination of the plastic molding material volume factor
1 Scope
This standard specifies the method for the determination of density and apparent density of molding the molding material when not molded after volume factor.
Molding material volume factor is to calculate the minimum volume of the mold cavity design basic data.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
1033.1-2008 non-plastic foam density measurement GB/T Part 1. Immersion method, liquid pyknometer method and titration method
(ISO 1183.1.2004, IDT)
1977 Determination of the plastic material flowing from the provisions of the funnel Apparent density. ISO 60
1977 Determination of the plastic can not flow from the provisions of the funnel material apparent density. ISO 61
3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Volume ratio of volume after its molding quantification of the molding material.
Note. The ratio of the density of the apparent density of molding material and molding it is also not the time of molding after.
4 test temperature
Apparent density and density calculations required volume factor should be measured at the same temperature.
5 steps
5.1 according to ISO 60. 1977 or ISO 61. 1977 Determination of apparent density of molding material is not.
5.2 according to GB/T 1033.1-2008 Determination of density after molding material.
6 The results are shown
According to equation (1) to calculate the volume coefficient of plastic molding.
ρu
(1)
Where.
--- PM density of material after molding, in grams per milliliter (g/mL);
Ρu --- No apparent density of the molding material, in grams per milliliter (g/mL).
Test results take two significant figures.
Note. In calculating the volume factor, after molding density would be its relative density (water as reference material) agree on the value.
