4.1 Inorganic fibrous thermal insulation can contain varying amounts of non-fibrous material. Non-fibrous material does not contribute to the insulating value of the insulation and therefore a procedure for determining that amount is desirable. Several specifications refer to shot content and percent (%) retained on various screen sizes determined by this test method.1.1 This test method covers a procedure for determining the non-fibrous content (shot) of man-made rock and slag mineral fiber insulation. The procedure covers a dry sieve analysis method to distinguish between fiberized and non-fiberized (shot) portions of a specimen of man-made rock and slag mineral fiber insulation specimen.1.2 This test method does not apply to rock or slag materials containing any components other than rock and slag mineral fiber, oil, and organic thermal setting binders. Products containing other types of fibers, inorganic binders, or refractory clays are excluded.NOTE 1: Industrial oils such as mineral or synthetic can be used to enhance the hydrophobic qualities and dust suppression.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This test method uses a ratio turbidimetric optical system to measure the turbidity of insulating oils relative to turbidity standards. Cloudiness or turbidity is attributed to matter whose diameter is approximately 20 % of the wavelength of the incident light. Increasing turbidity signifies increasing transformer fluid contamination, either from external sources or internal chemical reactions (such as oxidation) that produce fine particulate matter. Other turbidity sources, such as water droplets or gas bubbles, are not of interest in this evaluation of insulating oils. The elimination of these interferences is described in 6.2 and 6.6. This test method quantifies changes which may not be apparent to the unaided human eye.1.1 This test method covers the laboratory procedure that ascertains the quantity of suspensions in insulating oils of petroleum origin using a nephelometric measurement technique to determine the fluid's turbidity. This test method is designed to reveal changes that may occur to these oils.1.2 This test method is applicable for turbidities in the range of 0.1 to 500 Nephelometric Turbidity Units (NTU).1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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.

4.1 Blown density is used to develop loose-fill coverage charts. Data for blown density vs thickness is used in the development of a variable blown density presentation for loose-fill insulation.4.2 Thermal resistance (and conductivity) of loose-fill mineral fiber insulation depends on density and thickness. The resulting blown density data is useful in developing an expression for apparent thermal conductivity as a function of density. This will in turn aid the manufacturer in developing coverage information for packages of loose-fill insulation.4.3 The blown density obtained in this method is for the thickness of the test only. The relationship of blown density with thickness can be determined by repeating the procedures outlined here using different thicknesses.4.4 These procedures are not the same as the test method described in Test Method C1374. Depending on the test conditions utilized, the blown density may, or may not, represent the installed density values obtained by using Test Method C1374.4.5 This guide can be used to develop appropriate blowing machine settings to achieve a target blown density at a predetermined thickness.1.1 This guide describes two alternate procedures for determining blown density at a predetermined thickness or a range of thicknesses expected in field applications of mineral fiber loose-fill insulation.1.2 This guide involves blowing a sample of loose-fill insulation into a test frame of known volume, measuring the weight of the insulation captured and calculating the blown density.1.3 This guide is intended for pneumatically-applied loose-fill mineral fiber insulation designed for use in horizontal open attic spaces.1.4 This guide is intended for product design and product auditing by manufacturers of loose-fill insulation. This guide is adaptable as a plant quality control procedure.1.5 This guide does not predict the aged density of the mineral fiber loose-fill insulation.1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
