ASTM D6150-24

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope*
1.1 This test method describes a procedure for the determination of the relative volatility of polyvinyl chloride plastisols and
organosols at elevated temperatures.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes,
excluding those in tables and figures, shall not be considered as requirements of this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and healthsafety, health, and environmental practices and determine
the applicability of regulatory limitations prior to use.
NOTE 1—There is no known ISO equivalent to this standard.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions—The terms used in this test method are in accordance with Terminology D883 and abbreviations are in accordance
with Terminology D1600, unless otherwise indicated.
3.2 For terms relating to precision and bias and associated issues, the terms used in this test method are in accordance with the
definitions in Terminology E456.
4. Summary of Test Method
4.1 Plastisols or organosols are weighed in aluminum dishes and heated in a circulating air oven at 177°C (350°F) for 10 min.
The specimens are removed from the oven, cooled, and reweighed. The weight loss is determined and reported as either percent
weight loss or weight loss per unit area of exposed surface.
5. Significance and Use
5.1 The volatile components of a plastisol or organosol influence the weight loss during processing. It is possible that this
information will be useful to the producer and user and to environmental interests for estimating the volatiles emitted by the
plastisol or organosol during processing.
5.2 Results obtained by this test method are not strictly equivalent to those experienced during product processing wherein
conditions of temperature, air flow, coating mass, and configuration are potentially quite different.
5.3 This test method is not necessarily applicable to all types of plastisol and organosol applications. Any change in the specified
testing time or temperature to accommodate unique applications shall be included in the report (see 7.3).
6. Apparatus
6.1 Oven, forced–ventilation laboratory oven, Type II, Grade A, with 100 to 200 air exchanges/h as specified in Specification
E145.
6.1.1 It is acceptable to use a rotating turntable drive at a rate of 1 to 6.
6.1.2 It is acceptable to use a tray to fit the turntable to minimize the temperature drop in the oven.
6.2 Aluminum Foil Dishes, 57 mm in diameter by 18 mm high with a smooth (planar) bottom surface.
7. Procedure
7.1 Ensure the plastisol or organosol is homogeneous. If necessary, mix the sample by hand or mechanical stirrer until
homogeneous and deaerate.
7.2 Tare three aluminum dishes to the nearest 0.1 mg.
7.3 Add the plastisol or organosol specimen in such a manner as to entirely cover the bottom of the dish. The weight added to
each dish shall vary by only 60.1 g of the selected weight. If the thickness of the final product cannot be accurately determined,
add 6.0 6 0.1 g to each dish.
NOTE 2—A more representative measurement of weight loss is possible if the thickness of the sample in the aluminum dish approaches the thickness of
the material during processing. The weight of the specimens added to the dish is allowed to vary according to the application.
7.4 Reweigh the dishes to the nearest 0.1 mg.
7.5 Place only three dishes from a single specimen in the oven on a shelf or turntable, or both, perpendicular to the airflow.
7.5.1 If a rotating turntable is used, place the dishes on the turntable equally spaced from the center.
D6150 − 24
7.5.2 Due to the short heating time, place the specimens into the oven as quickly as possible to minimize the temperature drop
in the oven.
7.6 Heat the aluminum foil dishes containing the specimens in the forced draft oven (6.1) for 10 min 6 20 s at 177°C (350°F).
7.7 Remove the dishes from the oven, place immediately in a desiccator, cool for 15 min to ambient temperature, and weigh to
0.1 mg.
8. Calculation
8.1 Calculate the percent volatile matter, V, in the plastisol or organosol as follows:
V 5 @~~W 2 W !2 ~W 2 W !!/~W 2 W !# ×100 (1)
2 1 3 1 2 1
where:
W = weight of aluminum foil dish,
W = weight of dish plus specimen, and
W = weight of dish plus specimen after heating.
8.2 Calculate the weight loss relative to unit area of exposed surface as follows:
2 2 2
weight loss, g/mm 5 @~W 2 W !2 ~W 2 W !#/~πd /4!5 1.273@~W 2 W !2 ~W 2 W !#/d (2)
2 1 3 1 3 1 2 1
where:
W = weight of aluminum foil dish,
W = weight of dish plus specimen,
W = weight of dish plus specimen after heating, and
d = external diameter of specimen after heating in mm.
