Arti dan Tujuan
5.1 Kepadatan adalah berat per satuan volume. Ini adalah properti kunci untuk identifikasi, characterization and quality control of various materials. Density measurements expressed in weight per gallon are commonly used to check paint quality. If the density is not within the specification, there is a high probability of mischarging or other serious problems.

5.2 The test method is suitable for determining the density of paint and related products and components in liquid form. It is particularly applicable when the fluid viscosity is too high or the components are too volatile to determine the density equilibrium.

5.3 This test method provides the maximum accuracy required to determine the hiding power. It is equally suitable for jobs requiring lower accuracy, ignoring recalibration directions and considering temperature differences, and using “weight per gallon” cups as containers.

5.4 Several manufacturers offer automatic equipment for measuring density (see Test Method D4052). Such devices have been used for resins and latex as well as oils and solvents. The results need to be examined very carefully before such devices can be used for a given product. Especially for paints, tinta, and resins, bonding, scaling, and other interference with operation may occur.

Ruang lingkup
1.1 This test method covers the density measurement of paints, tinta, pernis, varnishes and their constituents (except pigments) in liquid form.

1.2 Test method D1963 can be used to determine specific gravity and density in order to obtain higher accuracy when dealing with non-tinted materials (dry oils, varnishments, resins and related materials).

1.3 Nilai yang dinyatakan dalam satuan SI harus dianggap sebagai standar. Nilai yang diberikan dalam tanda kurung hanya untuk referensi.

1.3.1 Exception-Density values are expressed in inch-pounds.

1.4 Standar ini tidak dimaksudkan untuk mengatasi semua masalah keselamatan, jika ada, terkait dengan penggunaannya. Pengguna standar ini bertanggung jawab untuk menetapkan keselamatan yang sesuai, praktik kesehatan dan lingkungan dan untuk menentukan penerapan pembatasan peraturan sebelum digunakan. Specific precautions are given in 8.1.1.1.

1.5 Standar internasional ini telah dikembangkan sesuai dengan prinsip-prinsip standardisasi yang diakui secara internasional yang ditetapkan dalam Keputusan Prinsip-Prinsip Pengembangan Standar Internasional, Pedoman dan Rekomendasi yang dikeluarkan oleh Komite Hambatan Teknis Perdagangan Organisasi Perdagangan Dunia.
