Voorbeeldzinnen

1. porosity
2. Filter paper, medium porosity, of diameter about 15 cm
3. The hydrogen components must not show evidence of porosity.
4. 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
5. 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.
6. 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.
7. 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).
8. 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:
