ISO Views Total views. They shall be of a convenient size to give adequate clearance between the specimen and the immersion vessel and should preferably have a mass of at least 1 g. For improved accuracy, the dependence of the density of air on pressure and temperature can be taken into account:

It is the responsibility of the user of this part of ISO to establish appropriate health and safety practices and to determine the applicability of any regulatory limitations prior to use. Method A: Immersion method, for solid plastics except for powders in void-free form. Method B: Liquid pyknometer method, for particles, powders, flakes, granules or small pieces of finished parts.

Method C: Titration method, for plastics in any void-free form. Density is frequently used to follow variations in physical structure or composition of plastic materials. Density may also be useful in assessing the uniformity of samples or specimens. Often the density of plastic materials will depend upon the choice of specimen preparation method.

When this is the case, precise details of the specimen preparation method will have to be included in the appropriate material specification. This note is applicable to all three methods. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies.

ISO , Quantities and units — Part 3: Mechanics ISO In general, conditioning specimens to constant temperature is not required, because the determination itself brings the specimen to the constant temperature of the test. Specimens which change in density during the test to such an extent that the change is greater than the required accuracy shall be conditioned prior to measurement in accordance with the applicable material specification.

When changes in density with time or atmospheric conditions are the primary purpose of the measurements, the specimens shall be conditioned as described in the material specification and, if no material specification exists, then as agreed upon by the interested parties. NOTE An automatically operating instrument may be used. The calculation of density may be done automatically using a computer.

The liquid or solution with which the specimen comes into contact during the measurement shall have no effect on the specimen.

The density of immersion liquids other than distilled water need not be measured provided they are obtained from an accredited source and are accompanied by certificate. They shall be of a convenient size to give adequate clearance between the specimen and the immersion vessel and should preferably have a mass of at least 1 g. When cutting specimens from larger samples, proper equipment shall be used to ensure that the characteristics of the material do not change.

The surface of the specimen shall be smooth and free from cavities to minimize the entrapment of air bubbles upon immersion in the liquid, otherwise errors will be introduced. Weigh specimens of mass less than or equal to 10 g to the nearest 0,1 mg.

Weigh those of mass greater than 10 g to the nearest 1 mg. Record the mass of the specimen. Remove any adhering air bubbles with a fine wire. Weigh the immersed specimen to the nearest 0,1 mg. Weigh the pyknometer 5. Use the liquid bath 5. For specimens having a density less than that of the immersion liquid, the test may be performed in exactly the same way as described above, with the following exception: The sinker may be considered as a part of the suspension wire.

In this case, the upthrust exerted by the immersion liquid on the sinker shall be allowed for by using the following equation, rather than Equation 2 , to calculate the density of the specimen: Perform the test on a minimum of three specimens and calculate the mean result to three decimal 5.
