Method of eye irritation test in vitro for hair dye cosmetic products-Bovine cornel opacity and permeability test
Turbidity is undesirable in drinking water, plant effluent waters, water for food and beverage processing, and for a large number of other water-dependent manufacturing processes. Removal is often accomplished by coagulation, settling, and filtration. Measurement of turbidity provides a rapid means of process control for when, how, and to what extent the water must be treated to meet specifications. This test method is suitable to turbidity such as that found in drinking water, process water, and high purity industrial water. When reporting the measured result, appropriate units should also be reported. The units are reflective of the technology used to generate the result, and if necessary, provide more adequate comparison to historical data sets. Table 1 describes technologies and reporting results (see also Refs (1),(2),(3)). Those technologies listed are appropriate for the range of measurement prescribed in this method. Others may come available in the future. Fig. X5.1 provides a flow chart to aid in selection of the appropriate technology for low-level static turbidity applications. If a design that falls outside of the criteria listed in Table 1 is used, the turbidity should be reported in turbidity units (TU) with a subscripted wavelength value to characterize the light source that was used. TABLE 1 Applicable Technologies Available for Performing Static Turbidity Measurements Below 5 NTU1.1 This test method covers the static determination of turbidity in water (see 4.1). 1.2 This test method is applicable to the measurement of turbidities under 5.0 nephelometric turbidity units (NTU). 1.3 This test method was tested on municipal drinking water, ultra-pure water and low turbidity samples. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices. 1.4 This test method uses calibration standards are defined in NTU values, but other assigned turbidity units are assumed to be equivalent. 1.5 This test method assigns traceable reporting units to the type of respective technology that was used to perform the measurement. Units are numerically equivalent with respect to the calibration standard. For example, a 1.0 NTU formazin standard is also equal to a 1.0 FNU standard, a 1.0 FNRU standard and so forth. 1.6 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. Refer to the MSDSs for all chemicals used in this procedure.

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.

This International Standard specifies four methods for the determinations of turbidity of water. Section 2 specifies semiquantitative methods, employed for example in field work: a) method using the transparency testing tube (suitable for pure and lightly polluted water); b) method using the transparency testing disk (especially suitable for surface water). Section 3 specifies quantitative methods using optical turbi-dimeters: a) method by measuring diffused radiation, applicable to water of low turbidity (for example drinking water). Depen-ding on the instrument design, it may also be used for waters of higher turbidity; b) method by measuring the attenuation of a radiant flux, more suitable for highly turbid waters (for example waste or polluted waters). Measurements of turbidity can be affected by the presence of dissolved light-absorbing substances (substances imparting colour). Such effects can be minimized, however, by perform-ing measurements at wavelengths greater than 800 nm. Only a blue colour, which may be found in certain polluted waters, slightly affects measurements of turbidity in this region of the spectrum. Air bubbles may also interfere with measurements but such interference may be minimized by careful handling of the samples.

This International Standard specifies a test method for the measurement of exhaust gas opacity from compression-ignition (diesel-)engined vehicles. It describes the measurement of exhaust opacity under quasi-steady conditions at a single speed at full load, and is designed to ensure a correlation with measurement under steady-state conditions. NOTE — This method is most suitable as an inspection station test but the test may also be carried out on the road. The lug-down test specrfied in ISO 7644 is only suited to an inspection station test
