Sampling procedures for inspection by attributes — Part 4: Procedures for assessment of declared qua...
This document establishes single sampling plans for conformance testing, i.e., for assessing whether the quality level of a relevant audit population (lot, process, inventory, file etc) conforms to a declared value. Sampling plans are provided corresponding to four levels of discriminatory ability. The limiting quality ratio (LQR) (see Clause 4) of each sampling plan is given for reference. For…

Textile floor coverings — Installation practices — General
This document sets out the requirements for installing textile floor coverings (carpets). It gives details of the work necessary in preparing subfloor surfaces together with the procedures that are to be adopted where textile floor coverings are laid over various types of subfloors and underlays and where subfloor heating units are installed.
NOTE This document addresses needle insertion…
Vacuum technology — Standard methods for measuring vacuum-pump performance — Part 2: Positive displa...
This document specifies methods for measuring the volume flow rate, base pressure, water vapour tolerance, power consumption, and the lowest start-up temperature of positive displacement vacuum pumps, which discharge gas against atmospheric pressure and with a usual base pressure <10 kPa.
In this document, it is necessary to use the determinations of volume flow rate and base pressure…
Vacuum technology — Standard methods for measuring vacuum-pump performance — Part 1: General descrip...
This document specifies three methods for measuring the volume flow rate and one method each for measuring the base pressure, the compression ratio, and the critical backing pressure of a vacuum pump.
The first method for measuring the volume flow rate (the throughput method) is the basic concept, in which a steady gas flow is injected into the pump while the inlet pressure is measured. In…
