Testing methods for collection efficiency of airborne microbe samplers (Amendment 1)
This guide is intended for use in a biotechnology laboratory when the need arises to identify a preparation containing M13 bacteriophage or DNA.1.1 This guide covers the identification of bacteriophage M13 used in biotechnology.1.2 There are many variants of M13 that have been developed specifically for cloning technology. These variants have foreign DNA inserted into the M13 genome, causing the M13 to differ in size and genotype.1.3 If the M13 is to be used to construct a recombinant molecule, then the criteria described in Section 6 should be used to characterize the newly made DNA.

ISO 21528-2:2004 specifies a method, without pre-enrichment, for the enumeration of Enterobacteriaceae. It is applicable to products intended for human consumption and the feeding of animals, and environmental samples in the area of food production and food handling. Enumeration is carried out by counting colonies in a solid medium after incubation at 37 °C. This technique is recommended when the number of colonies sought is expected to be more than 100 per millilitre or per gram of the test sample.

1.1 This test method describes the procedures for determining the mass concentration of particulate matter in gaseous streams using an automated, in-stack test method. This method, an in-situ, inertial microbalance, is based on inertial mass measurement using a hollow tube oscillator. This method is describes the design of the apparatus, operating procedure, and the quality control procedures required to obtain the levels of precision and accuracy stated.1.2 This method is suitable for collecting and measuring filterable particulate matter concentrations in the ranges 0.2 mg/m3 and above taken in effluent ducts and stacks.1.3 This test method may be used for calibration of automated monitoring systems (AMS). If the emission gas contains unstable, reactive, or semi-volatile substances, the measurement will depend on the filtration temperature, and this method (and other in-stack methods) may be more applicable than out-stack methods for the calibration of automated monitoring systems.1.4 This test method can be employed in sources having gas temperature up to 200176;C and having gas velocities from 3 to 27 m/s.1.5 This test method includes a description of equipment and methods to be used for obtaining and analyzing samples and a description of the procedure used for calculating the results.1.6 Stack temperatures limitation for this test method is approximately 200176;C (392176;F).1.7 This test method may be also be limited from use in sampling gas streams that contain fluoride, or other reactive species having the potential to react with or within the sample train.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
