Voorbeeldzinnen

1. porosity
2. pore space volume (including porosity distribution);
3. Filter paper, medium porosity, of diameter about 15 cm
4. The hydrogen components must not show evidence of porosity.
5. Extraction thimbles, free of matter soluble in light petroleum and having a porosity consistent with the requirements of point 4.1.
6. If exact data are not available, default values of 1,4 tonnes/m3 for the dry bulk density and 0,5 m3/m3 for the porosity should be used.
7. mineralisation typology, their chemistry and mineralogy, including physical properties such as density, porosity, particle size distribution, water content, covering worked minerals, gangue minerals, hydrothermal newly-formed minerals,
8. P average porosity of the sedimented tailings (m3/m3) defined as the ratio of the volume of voids to the total volume of sedimented tailings
9. External leakage test: the purpose of the test is to provide evidence that the hydrogen components are free from external leakage. The hydrogen components must not show evidence of porosity.
10. Instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes
11. A component shall be free from leakage through stem or body seals or other joints, and shall not show evidence of porosity in casting when tested as described in paragraph 5.3. at any aerostatic pressure between 0 and the pressure shown in Table 3. The above prescriptions are deemed to be satisfied, if the provisions of paragraph 5.4. are met.
12. A component shall be free from leakage through stem or body seals or other joints, and shall not show evidence of porosity in casting when tested as described in paragraph 5.3. at any aerostatic pressure between 0 and the pressure shown in Table 3.
13. Demand-side substitutability therefore is limited, since the grades of wet laid fibre materials need to match very strict requirements in order to ensure compatibility with the converting machines and specific product requirements of the end application (e.g. porosity, thickness, flexibility, compliance with regulatory standards).
14. Instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity, porosity, expansion, surface tension or the like; instruments and apparatus for measuring or checking quantities of heat, sound or light (including exposure meters); microtomes:
