Part 18: Detection and enumeration of moulds — Sampling by impaction
TECHNICAL CORRIGENDUM 1
Technical Corrigendum 1 to ISO 16000-18:2011 was prepared by Technical Committee ISO/TC 146, Air quality, Subcommittee SC 6, Indoor air.
Page 8, 9.1, paragraph 2
Delete “2 %” and “±2 %”, insert “5 %” and “±5 %”, respectively, so that the paragraph reads as follows.
The usual verification of the flow rate (function control) depends on the stability of the apparatus. A complete calibration shall be carried out prior to starting a new measurement campaign or following significant changes, e.g. when new or repaired equipment is used or after pump servicing. If the flow rate determined using the transfer standard deviates by more than 5 % from the value required for correct operation of the inlet, the flow controller shall be adjusted according to the manufacturer's instructions. Make sure that the air flow does not fluctuate by more than ±5 % during sampling and that the time to reach the desired sampling velocity in the beginning of the sampling process is kept as short as possible to minimize the influence on the sample volume.
