ISO 14644-5:2004 specifies basic requirements for cleanroom operations. It is intended for those planning to use and operate a cleanroom. Aspects of safety that have no direct bearing on contamination control are not considered in this part of ISO 14644 and national and local safety regulations must be observed. This document considers all classes of cleanrooms used to produce all types of products. Therefore, it is broad in application and does not address specific requirements for individual industries. Methods and programmes for routine monitoring within cleanrooms are not covered in detail in this part of ISO 14644 but reference should be made to ISO 14644-2 and ISO 14644-3 for monitoring particles, and ISO 14698-1 and ISO 14698-2 for monitoring micro-organisms.

This document specifies the rotating drum test apparatus and associated test method for the reproducible production of dust from a bulk material under standard conditions, and the measurement of the inhalable, thoracic and respirable dustiness mass fractions, with reference to existing European Standards, where relevant (see Clause 6). This method is suitable for general bulk material handling processes, including all those processes where the bulk material is dropped, or can be dropped. It differs from the continuous drop method presented in EN 15051 3 [4]. In EN 15051 2, the same bulk material is repeatedly dropped, whilst in EN 15051 3, the bulk material is dropped only once, but continuously. Furthermore, this document specifies the environmental conditions, the sample handling and analytical procedures, and the method of calculating and presenting the results. A categorization scheme for dustiness is specified, to provide a standardized way to express and communicate the results to users of the bulk materials. This document is applicable to powdered, granular or pelletized bulk materials. A standard sample volume is used. This document is not applicable to test the dust released when solid bulk materials are mechanically reduced (e.g. cut, crushed).

This document describes the methodology for measuring and characterizing the dustiness of bulk materials that contain or release respirable NOAA or other respirable particles, under standard and reproducible conditions and specifies for that purpose the vortex shaker method. This document specifies the selection of instruments and devices and the procedures for calculating and presenting the results. It also gives guidelines on the evaluation and reporting of the data. The methodology described in this document enables: a) the measurement of the respirable dustiness mass fraction; b) the measurement of the number-based dustiness index of respirable particles in the particle size range from about 10 nm to about 1 µm; c) the measurement of the number-based emission rate of respirable particles in the particle size range from about 10 nm to about 1 µm; d) the measurement of the number-based particle size distribution of the released respirable aerosol in the particle size range from about 10 nm to 10 µm; e) the collection of released airborne particles in the respirable fraction for subsequent observations and analysis by electron microscopy. This document is applicable to the testing of a wide range of bulk materials including nanomaterials in powder form. NOTE 1 With slightly different configurations of the method specified in this document, dustiness of a series of carbon nanotubes has been investigated ([5] to [10]). On the basis of this published work, the vortex shaker method is also applicable to nanofibres and nanoplates. This document is not applicable to millimetre-sized granules or pellets containing nano-objects in either unbound, bound uncoated and coated forms. NOTE 2 The restrictions with regard to the application of the vortex shaker method on different kinds of nanomaterials result from the configuration of the vortex shaker apparatus as well as from the small size of the test sample required. Eventually, if future work will be able to provide accurate and repeatable data demonstrating that an extension of the method applicability is possible, the intention is to revise this document and to introduce further cases of method application. NOTE 3 As observed in the pre-normative research project [4], the vortex shaker method specified in this document provides a more energetic aerosolization than the rotating drum, the continuous drop and the small rotating drum methods specified in EN 17199 2 [1], EN 17199 3 [2] and EN 17199 4 [3], respectively. The vortex shaker method can better simulate high energy dust dispersion operations or processes where vibration or shaking is applied or even describe a worst case scenario in a workplace, including the (non-recommended) practice of cleaning contaminated worker coveralls and dry work surfaces with compressed air. NOTE 4 Currently no classification scheme in terms of dustiness indices or emission rates has been established according to the vortex shaker method. Eventually, when a large number of measurement data has been obtained, the intention is to revise the document and to introduce such a classification scheme, if applicable.

This dcoument specifies a method for the determination of fluoro-, chloro-, bromo- and iodo-organic compounds (AOF, AOCl, AOBr, AOI). Due to the high solubility of AgF in water the scope of ISO 9562 is restricted to Cl-, Br- and I-organic compounds (AOX, calculated as chlorine) because of the applied argentometric detection. The PN follows the proven AOX ISO 9562 method: adsorption of organohalogen compounds on activated carbon, oxidative combustion at 1000 °C with following alterations: constant water feed during combustion (hydropyrolysis), absorption of combustion gases in water, halide specific detection using ionchromatography. The method is applicable for the determination of 2 µg/l AOF, expressed as F 10 µg/l AOCl, expressed as Cl 1 µg/l AOBr, expressed as Br 1 µg/l AOI, expressed as I. Samples for determination of AOF are treated differently than samples for the determination of AOCl, AOBr and AOI. - Samples for determination of AOF are not acidified. The adsorption takes place under unchanged pH conditions. Washing is also performed with a neutral washing solution. - Samples for the determination of AOCl, AOBr and AOI are adjusted to a pH value 2 with nitric acid, the adsorption and washing take place in a nitric acid environment.

This standard will specify a large-scale fire test method for measuring the heat release rates (HRR) and the smoke-production rates (SPR) of wall systems. The fire scenario covered in this document is representative of severe fires originating in near wall or corner locations of an exterior or interior wall construction. Severe fire exposure to wall systems, on the order of 100 kW/m2 heat flux, are targeted in this test method. For this standard, the test setup is placed under an ISO 24473 compliant large-scale calorimeter of a minimum 3.5 MW chemical HRR capacity. An existing large-scale fire test, viz. the 16-ft parallel panel test (16-ft PPT) of the consensus ASNI/FM 4880 standard, is submitted to be used as the basis of the proposed ISO standard. The test method is not applicable for scenarios where a fire initiates within an air cavity, if present, of an exterior wall system. The test method does not incorporate a window structure and hence cannot cover the hazard from inadequately protected window openings in a post-flashover fire scenario.

This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s) specified e.g. in regulations. NOTE      Many national and international regulations classify liquids as presenting a flammable hazard based on their flash point, as determined by a recognized method. Some of these regulations allow a derogation if the substance cannot “sustain combustion” at some specified temperature(s). The procedure is applicable to paints (including water-borne paints), varnishes, paint binders, solvents, petroleum or related products and adhesives, that have a flash point. It is not applicable to painted surfaces in respect of assessing their potential fire hazards. This test method is applicable, in addition to test methods for flash point, for assessing the fire hazard of a product.
