5.1 Stress is applied as pressure over the area of the flatjack. In the case of multi-wythe masonry, stress is estimated only in the wythe in which the flatjack is inserted. Stress in other wythes may be different.1.1 This test method covers the determination of the average compressive stress in existing unreinforced solid-unit masonry (see Note 1). This test method concerns the measurement of in-situ compressive stress in existing masonry by use of thin, bladder-like flatjack devices that are installed in cut mortar joints in the masonry wall. This test method provides a relatively non-destructive means of determining masonry properties in place.NOTE 1: Solid-unit masonry is that built with stone, concrete, or clay units whose net area is equal to or greater than 75 % of the gross area.1.2 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.1.3 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.1.4 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.

It is intended that this practice be used to provide a sample representative of the coal from which it is collected. Because of the variability of coal and the wide variety of mechanical sampling equipment available, caution should be used in all stages of the sample collection process, the design of sampling system specifications, the equipment procurement and the acceptance testing of installed equipment.After removal from the sampling system and further preparation (Practice D 2013), the sample may be analyzed for a number of different parameters. These parameters may define the lot's value, its ability to meet specifications, its environmental impact, as well as other properties.1.1 This practice covers procedures for the mechanical collection of a sample under Classification I-B-1 and I-B-2 (Practice D 2234/D 2234M) and the within-system preparation (reduction and division) of gross samples utilizing various components of the mechanical sampling system.1.2 This practice describes mechanical sampling procedures for coals (1) by size and condition of preparation (for example, mechanically cleaned coal or raw coal) and (2) by sampling characteristics.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, use each system independently of the other. Combining values from the two systems may result in nonconformance with the standard.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.

5.1 The practice can be used to evaluate coupon materials of any composition, insofar as the coupon can be prepared small enough to fit inside a 50-ml conical tube.5.2 This practice defines procedures that are quantitative, scalable, rapid, sensitive, safe, reduces consumables, minimizes labor and addresses statistical confidence (1, 2, 4).5.2.1 Quantitative—The total number of spores per coupon is determined by dilution-plating, and all spores remaining on the coupon are assayed for activity in the extraction tube to provide confidence that 100 % of spores were assayed.5.2.2 Statistical Confidence—The use of five independent preparations of spore inoculum for a statistical N of 5.5.2.3 Sensitivity—Allows for complete detection of all viable spores inoculated on a coupon, including the spores that remain attached to the coupon.5.2.4 Safety—Inoculated coupons are contained within 0.2 µm filter-capped 50-ml conical tubes. The 0.2 µm filter allows vaporous decontaminants to pass through while preventing escape of spores, thereby providing an important level of containment when working with pathogenic strains.5.2.5 Simplicity of Testing—Tests and extractions are performed in the same 50-ml conical tube to minimize handling steps.5.2.6 Scalable and Rapid—A maximum of 36 samples can be processed in 1 h by two technicians; a total of 300 samples have been processed by six technicians in 5 h (1-3).5.2.7 Wide application for numerous Bacillus species and strains.NOTE 1: This practice differs from similar quantitative methods (E2111, E2197 and E2414) in the size and variety of coupon materials available for testing, in the practical confidence of the statistics, the application of the decontaminant, scalability and sensitivity.1.1 This practice is used to quantify the efficacy of vaporous decontaminants on Bacillus spores dried on the surface of coupons made from porous and non-porous materials and contained within 0.2µm filter-capped tubes.1.2 This practice should be performed only by those trained in microbiological techniques, are familiar with antimicrobial (sporicidal) agents and with the end use of such products.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.
