5.1 Although there is little information available concerning the toxicological significance of aluminum in man, the American Water Works Association has established a water quality guideline or goal of a maximum of 0.05 mg/L. Under the National Pollution Discharge Elimination System (NPDES), some permits may set aluminum discharge limits. Some evidence does exist to indicate that low levels (5 mg/L) will interfere with activated sludge processes. For the above reasons monitoring of aluminum may be desirable.5.2 Aluminum is monitored in boiler make-up water, where alum has been used, to determine whether aluminum is present after pretreatment. Residual aluminum may consume ion exchange capacity or consume boiler water treatment chemicals added to stoichiometrically chelate hardness ions (that is, calcium and magnesium) in boiler feed water.5.3 Aluminum is monitored in cooling water make-up, since its presence may result in deactivation of anionic substances in scale or corrosion inhibitor treatment chemicals, or both. Deactivation may result in decreased performance of inhibitors.5.4 ICP-MS may also be appropriate but at a higher instrument cost. See Test Method D5673.1.1 This test method covers the direct flame atomic absorption determination of aluminum in the nitrous oxide-acetylene flame.1.2 This test method is applicable to waters containing dissolved and total recoverable aluminum in the range from 0.5 to 5.0 mg/L. Aluminum concentrations as high as approximately 50 mg/L can be determined using this test method without dilution. However, no precision and bias data are available for concentrations greater than 5.0 mg/L.1.3 This test method was tested on reagent, natural, and potable waters. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.1.4 The same digestion procedure may be used to determine total recoverable nickel (Test Methods D1886), chromium (Test Methods D1687), cobalt (Test Methods D3558), copper (Test Methods D1688), iron (Test Methods D1068), lead (Test Methods D3559), manganese (Test Methods D858), and zinc (Test Methods D1691).1.5 Precision and bias data have been obtained on reagent, natural, and potable waters. It is the responsibility of the user to ensure the validity of this test method on untested matrices.1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 7.5, 8.4, and Note 2.1.8 Former Test Methods A (Fluorometric) and B and C (Spectrophotometric) were discontinued. Refer to Appendix X1 for historical information.1.9 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.

5.1 This test method is intended solely for the shear testing of rivets and cold-heading wire and rod, and is not generally recommended for the determination of the shear strength of other products. For rivets, this test method is limited to rivets having a shank length equal to or greater than 2d.NOTE 2: The results of shear tests of specimens machined from products other than wire, rod, and rivets may be greatly dependent upon the orientation of the specimen within the original test material, and the direction in which the force is applied relative to the grain flow in the specimen.4 It is recommended that shear strengths of other products be determined by Test Method B769 for products greater than 0.250 in. (6.4 mm) and Test Method B831 for products less than 0.250 in. (6.4 mm). Shear strengths developed by this test method have been shown to vary from those developed by other methods.4 If this test method is used for shear testing of other products, variables such as those described in Test Method B769 should be identified and controlled.5.2 The results of shear tests are dependent upon the relative and absolute lengths of specimen which are sheared out, and those which are supported.4 The results of this test method should not be directly compared with those determined in other types of tests in which the methods of loading and supporting the specimen are different.5.3 The presence of a lubricant on the surfaces of the specimen and device may result in shear strengths up to 3 % lower than those determined in the absence of lubrication.NOTE 3: In order to be able to test rivets having shanks as short as 2d, the supported lengths of the specimen are 1/2 d (Fig. 1), although it is recognized that higher values of shear strength would be obtained if the supporting lengths were longer.Note—The tolerance applicable to the diameter of the specimen being shear tested must be recognized in drilling the hole in the device. It is recommended that the drilled hole size be equal to 1.02d plus 0.005 in. (0.12 mm) less the minus tolerance applicable to the specimen.S3   =   1/4 in. (6 mm) for d = 1/16 in. (1.5 mm) to 5/32 in. (4 mm), and   =   1/2 in. (12 mm) for d = 3/16 in. (5 mm) to 3/8 in. (10 mm).5.4 Investigations have determined that the shear strength decreases slightly as the clearance between the specimen diameter and the diameter of the test hole in the device increases, and that the effect of the clearance decreases with increasing specimen diameter. This test method (refer to Fig. 1) permits clearances for production testing which should affect shear strengths by no more than 2 %. For referee testing, the maximum clearance shall be 0.001 in. (0.03 mm).51.1 This test method covers the double shear testing of aluminum and aluminum alloy rivets with round, solid shanks and cold-heading wire and rod.2NOTE 1: Exceptions to this test method may be necessary in individual specifications or methods for tests for a particular material.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.
