ISO 2811-1:2016 specifies a method for determining the density of paints, varnishes and related products using a metal or Gay-Lussac pycnometer.

The method is limited to materials of low or medium viscosity at the temperature of test. The Hubbard pycnometer (see ISO 3507) can be used for highly viscous materials.

ISO 6953-1:2015 applies to

- manually controlled direct operated types (with or without relieving mechanism),

- manually controlled internal pilot operating types (e.g. nozzle flapper), and

- external pilot operated types.

In addition, it specifies the product marking requirements for pressure regulators and filter-regulators.

This part of ISO 6953 is applicable to compressed air pressure regulators with a rated inlet pressure of up to 2 500 kPa (25 bar) and an outlet adjustment pressure of up to 1 600 kPa (16 bar); and to filter-regulators with rated inlet and outlet pressures of up to 1 600 kPa (16 bar), in which the major contaminants are removed by mechanical means.

NOTE 1 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

The rated pressure should be selected from the preferred pressures listed in ISO 2944.

NOTE 2 The main characteristics to be included in the supplier's literature related to electrically modulated pneumatic continuous pressure control valves are specified in ISO 10094‑1.
