5.1 Protection of a species requires prevention of unacceptable effects on the number, health, and uses of individuals of that species. A life-cycle toxicity test is conducted to determine changes in the numbers of individuals and offspring of a test species resulting from effects of the test material on survival, growth, gender ratios, endocrine function, genetic expression, fertility and reproduction (1-3).3 Information might also be obtained on effects of the material on the health (4) and uses of the species. 5.2 Published information about the sensitivities of several meiobenthic copepods to several common metals and organic toxicants have been reviewed (5). For most compounds tested/published to date, A. tenuiremis is acutely less sensitive than mysid and penaeid shrimp, similarly sensitive as amphipods, and often more sensitive than cladocerans (daphniids, specifically). Reference 96-h aqueous toxicity tests with cadmium at 30 g/kg salinity showed an LC50 for A. tenuiremis adults of 213 to 234 μg/L (Chandler, unpub.). Reference toxicant tests with sodium dodecyl sulfate showed a 96-h LC50 of 13.3 to 15.5 mg/L (Chandler,unpubl.). A. tenuiremis is a comparatively new toxicity test organism, and an extensive database of species sensitivity to multiple aqueous test compounds is not yet available. Relative to other harpacticoid copepod studies in the literature, A. tenuiremis is more chronically sensitive than all other species published to date where there is comparative data (5). 5.3 Results of life-cycle tests with A. tenuiremis can be used to predict long-term effects at the individual and population levels likely to occur on copepods in field situations as a result of exposure under comparable conditions (1,2). 5.4 Results of life-cycle tests with A. tenuiremis might be used to compare the chronic sensitivities of different species and the chronic toxicities of different materials, and also study the effects of various environmental factors such as temperature, pH, and ultraviolet light on results of such tests. 5.5 Results of life-cycle tests with A. tenuiremis might be an important consideration when assessing the hazards of materials to aquatic organisms (see Guide E1023) or when deriving water quality criteria for aquatic organisms (6). 5.6 Results of a life-cycle test with A. tenuiremis might be useful for predicting the results of chronic tests on the same test material with the same species in another water or with another species in the same or a different water. Most such predictions take into account results of acute toxicity tests, and so the usefulness of the results from a life-cycle toxicity test with A. tenuiremis is greatly increased by also reporting the results of an acute toxicity test (see Guide E729) conducted under the same environmental conditions. 5.7 Results of life-cycle tests with A. tenuiremis might be useful for studying the biological availability of, and structure-activity relationships between, test materials. 5.8 Results of life-cycle tests with A. tenuiremis will depend on temperature, quality of food, composition of seawater, condition of test organisms, and other factors. 5.9 Life-cycle tests with A. tenuiremis are conducted on copepods reared individually in microwells of 96-well microplates. Thus they can be useful for studying endocrine, pre-zygotic and gender-specific toxicities of test materials (1-3). 1.1 This guide describes procedures for obtaining laboratory data concerning the adverse effects of a test material added to seawater, but not to food, on the marine copepod Amphiascus tenuiremis , during continuous exposures of individuals, from immediately after birth, until after the beginning of reproduction using a 200 μL renewal microplate-culturing technique. The following data are checked and recorded during the test period: stage-specific survival, number of days it takes for development from a first stage nauplius to a reproductively mature copepod, gender ratios, number of days for a female to extrude first and subsequent broods, number of days between first (and subsequent) brood extrusion(s) and hatching of first-generation nauplii, number of hatched and surviving nauplii, number of unhatched or necrotic eggs and aborted unhatching eggsacs, and the total number of females able to produce viable offspring over the entire mating period. This microplate-based full life-cycle toxicity test has a duration of approximately 17 days for toxicants that do not delay development. These procedures probably will be useful for conducting life-cycle toxicity tests with other species of copepods, although modifications might be necessary. 1.2 These procedures are applicable to most chemicals, either individually, or in formulations, commercial products, or known mixtures, that can be measured accurately at the necessary concentration in water. With appropriate modifications these procedures can be used to conduct tests on temperature, dissolved oxygen, and pH and on such materials as aqueous effluents (see also Guide E1192), sediment pore waters, and surface waters. Renewal microplate tests might not be applicable to materials that have a high oxygen demand, are highly volatile, are rapidly transformed (biologically or chemically) in aqueous solutions, or are removed from test solutions in substantial quantities by the test chambers or organisms during the test. If the concentration of dissolved oxygen falls below 50 % of saturation, or the concentration of test material in the test solution decreases by more than 20 % between renewals, it might be desirable to renew the solutions more often. 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 and health practices and determine the applicability of regulatory requirements prior to use.

4.1 The sound absorption of a material that covers a flat surface depends not only on the physical properties of the material but also on the way in which the material is mounted over the surface. The mountings specified in these practices are intended to simulate in the laboratory conditions that exist in normal use.4.2 Some of the specified mountings require special fixtures or minor deviations from normal practice. These fixtures or deviations are to be used only during laboratory tests and should not be specified for practical installations. They are noted in the specifications for the mountings in question by the phrase “for laboratory testing only.”4.3 Test reports may refer to these mountings by type designation instead of providing a detailed description of the mounting used.1.1 These practices cover test specimen mountings to be used during sound absorption tests performed in accordance with Test Method C423.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.3 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 Protection of a species requires prevention of unacceptable effects on the number, weight, health, and uses of the individuals of that species. A life-cycle toxicity test is conducted to determine what changes in the numbers and weights of individuals of the test species result from effects of the test material on survival, growth, and reproduction. Information might also be obtained on effects of the material on the health and uses of the species.5.2 Results of life-cycle tests with mysids might be used to predict long-term effects likely to occur on mysids in field situations as a result of exposure under comparable conditions.5.3 Results of life-cycle tests with mysids might be used to compare the chronic sensitivities of different species and the chronic toxicities of different materials, and also to study the effects of various environmental factors on results of such tests.5.4 Results of life-cycle tests with mysids might be an important consideration when assessing the hazards of materials to aquatic organisms (see Guide E1023) or when deriving water quality criteria for aquatic organisms (1).45.5 Results of a life-cycle test with mysids might be useful for predicting the results of chronic tests on the same test material with the same species in another water or with another species in the same or a different water (2).

These procedures will probably be useful for conducting life-cycle toxicity tests with other species of mysids, although modifications might be necessary.1.2 Other modifications of these procedures might be justified by special needs or circumstances. Although using appropriate procedures is more important than following prescribed procedures, results of tests conducted using unusual procedures are not likely to be comparable to results of many other tests. Comparison of results obtained using modified and unmodified versions of these procedures might provide useful information on new concepts and procedures for conducting life-cycle toxicity tests with saltwater mysids.1.3 These procedures are applicable to all chemicals, either individually or in formulations, commercial products, or known mixtures, that can be measured accurately at the necessary concentrations in water. With appropriate modifications, these procedures can be used to conduct tests on temperature, dissolved oxygen, and pH and on such materials as aqueous effluents (see also Guide E1192), leachates, oils, particulate matter, sediments, and surface waters.1.4 This guide is arranged as follows:  Section Referenced Documents 2Terminology 3Summary of Guide 4 5Hazards 7Apparatus 6 Facilities 6.1 Construction Materials 6.2 Metering System 6.3 Test Chambers 6.4 Cleaning 6.5 Acceptability 6.6Dilution Water 8 Requirements 8.1 Source 8.2 Treatment 8.3 Characterization 8.4Test Material 9 General 9.1 Stock Solution 9.2 Test Concentration(s) 9.3Test Organisms 10 Species 10.1 Age 10.2 Source 10.3 Brood Stock 10.4 Food 10.5 Handling 10.6 Harvesting Young 10.7 Quality 10.8Procedure 11 Experimental Design 11.1 Dissolved Oxygen 11.2 Temperature 11.3 Beginning the Test 11.4 Feeding 11.5 Cleaning 11.6 Duration of Test 11.7 Biological Data 11.8 Other Measurements 11.9Analytical Methodology 12Acceptability of Test 13Calculation 14Documentation 15Keywords 16Appendix    X1.

4.1 The axial force fatigue test is used to determine the effect of variations in material, geometry, surface condition, stress, and so forth, on the fatigue resistance of metallic materials subjected to direct stress for relatively large numbers of cycles. The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress.4.2 In order to verify that such basic fatigue data generated using this practice is comparable, reproducible, and correlated among laboratories, it may be advantageous to conduct a round-robin-type test program from a statistician's point of view. To do so would require the control or balance of what are often deemed nuisance variables; for example, hardness, cleanliness, grain size, composition, directionality, surface residual stress, surface finish, and so forth. Thus, when embarking on a program of this nature it is essential to define and maintain consistency a priori, as many variables as reasonably possible, with as much economy as prudent. All material variables, testing information, and procedures used should be reported so that correlation and reproducibility of results may be attempted in a fashion that is considered reasonably good current test practice.4.3 The results of the axial force fatigue test are suitable for application to design only when the specimen test conditions realistically simulate service conditions or some methodology of accounting for service conditions is available and clearly defined.1.1 This practice covers the procedure for the performance of axial force controlled fatigue tests to obtain the fatigue strength of metallic materials in the fatigue regime where the strains are predominately elastic, both upon initial loading and throughout the test. This practice is limited to the fatigue testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature.1.2 The use of this test method is limited to specimens and does not cover testing of full-scale components, structures, or consumer products.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 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.NOTE 1: The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice:E739 Practice for Statistical Analysis of Linear or Linearized Stress-Life (S-N) and Strain-Life (ε-N) Fatigue DataSTP 566 Handbook of Fatigue Testing2STP 588 Manual on Statistical Planning and Analysis for Fatigue Experiments3STP 731 Tables for Estimating Median Fatigue Limits41.5 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.

5.1 The severity of abrasive wear in any system will depend upon the abrasive particle size, shape and hardness, the magnitude of the stress imposed by the particle, and the frequency of contact of the abrasive particle. In this test method these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion (1 and 2). Since the test method does not attempt to duplicate all of the process conditions (abrasive size, shape, pressure, impact or corrosive elements), it should not be used to predict the exact resistance of a given material in a specific environment. The value of the test method lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Volume loss data obtained from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with test data obtained from a material whose life is known in the same environment. The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials.1.1 This test method covers laboratory procedures for determining the resistance of metallic materials to scratching abrasion by means of the wet sand/rubber wheel test. It is the intent of this procedure to provide data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.1.2 Abrasion test results are reported as volume loss in cubic millimetres. Materials of higher abrasion resistance will have a lower volume loss.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units 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.
