5.1 This guide is designed to help identify and integrate affected stakeholder interests and to include relevant scientific and technical information when developing occupational safety and health standards that include or are proposed to include an OEG.5.2 This guide shall be used when updating an occupational safety and health standard containing an OEG.5.3 While use of the CBSD process is required for occupational safety and health standards that include an OEG, it may also be used to improve stakeholder involvement and technical input for other occupational safety and health standards.5.4 The CBSD process is intended:(1) To obtain representation on the committee or subcommittee from sectors that are substantially impacted by a specific standard project; and(2) To obtain adequate input when the project requires review and analysis of information that is highly technical, very specialized, or not widely available.1.1 This guide presents a framework for a stakeholder-focused, consensus-based decision-making process for occupational safety and health standard development activities that include adoption or development of occupational exposure guidelines (OEGs) as a part of occupational health and safety standards.1.2 This guide applies to safety and health standard development activities in which an occupational exposure guideline will be included as one element of a comprehensive standard that addresses safety and health management strategies such as communication, monitoring, and controls. It is not meant to be used to develop an OEG apart from the context of such management strategies. In cases where other occupational exposure limit (OEL) establishing bodies have developed OELs, those may be reviewed, assimilated, or adapted rather than recreated ab initio.1.3 This guide does not replace existing consensus-based decision-making or committee participation processes that are used to develop safety and health standards. It is intended to be used in conjunction with such processes to improve scientific and technical input and stakeholder involvement in occupational safety and health decision-making for such standards.1.4 Limitations—This guide does not prescribe specific methods for generating or evaluating scientific and technical data related to assessing a particular occupational safety and health issue. Occupational safety and health standards apply to a wide variety of substances and occupational exposure circumstances. It is not possible to anticipate all situations where an OEG may be useful for a standard. This guide will be helpful in promoting appropriate balance and input, but the consensus process must deal with real-world complexities that individual standards may involve.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.

3.1 The provisions of this guide are intended to control and maintain the quality of recorded industrial electronic data from radioscopy and unrecorded magnetic and optical media only, and are not intended to control the acceptability of the materials or products examined. It is further intended that this guide be used as an adjunct to Guide E1000 and Practice E1255.3.2 The necessity for applying specific control procedures such as those described in this guide is dependent to a certain extent, on the degree to which the user adheres to good recording and storage practices as a matter of routine procedure. Such practices should follow the best-usage practices outlined by both the mechanism and media datasheets.3.3 This guide has been updated to provide guidance on the LTO and IBM 3592 families of data storage tape formats. The LTO and 3592 family of tape formats are the only remaining actively developed data tape formats.53.4 While the above indicated media are the only active digital tape formats on the market, archives of older media, including those with analog data, remain under retention requirements. The changes made here are conservative and do not negatively impact the storage of older media formats.3.5 The longevity in which the recorded data, either analog or digital, maintains its integrity on magnetic media varies greatly from one media to another. As such, it is considered best practice to duplicate the media at the manufacturer’s suggested interval to prevent loss of the recorded data through degradation. On average, this is every five years.1.1 This guide may be used for the control and maintenance of recorded and unrecorded magnetic and optical media of analog or digital electronic data from industrial radioscopy.1.2 Units—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. For specific precautionary statements, see Section 6.1.4 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.

4.1 Significance: 4.1.1 When conducting exposures in devices that use laboratory light sources, it is important to consider how well the accelerated test conditions will reproduce property changes and failure modes associated with end-use environments for the materials being tested. In addition, it is essential to consider the effects of variability in both the accelerated test and outdoor exposures when setting up exposure experiments and when interpreting the results from accelerated exposure tests.4.1.2 No laboratory exposure test can be specified as a total simulation of actual use conditions in outdoor environments. Results obtained from these laboratory accelerated exposures can be considered as representative of actual use exposures only when the degree of rank correlation has been established for the specific materials being tested and when the type of degradation is the same. The relative durability of materials in actual use conditions can be very different in different locations because of differences in UV radiation, time of wetness, relative humidity, temperature, pollutants, and other factors. Therefore, even if results from a specific exposure test conducted according to this practice are found to be useful for comparing the relative durability of materials exposed in a particular exterior environment, it cannot be assumed that they will be useful for determining relative durability of the same materials for a different environment.4.1.3 Even though it is very tempting, calculation of an acceleration factor relating x h or megajoules of radiant exposure in a laboratory accelerated test to y months or years of exterior exposure is not recommended. These acceleration factors are not valid for several reasons.4.1.3.1 Acceleration factors are material dependent and can be significantly different for each material and for different formulations of the same material.4.1.3.2 Variability in the rate of degradation in both actual use and laboratory accelerated exposure test can have a significant effect on the calculated acceleration factor.4.1.3.3 Acceleration factors calculated based on the ratio of irradiance between a laboratory light source and solar radiation, even when identical bandpasses are used, do not take into consideration the effects on a material of irradiance, temperature, moisture, and differences in spectral power distribution between the laboratory light source and solar radiation.NOTE 4: If use of an acceleration factor is desired in spite of the warnings given in this practice, such acceleration factors for a particular material are only valid if they are based on data from a sufficient number of separate exterior and laboratory accelerated exposures so that results used to relate times to failure in each exposure can be analyzed using statistical methods. An example of a statistical analysis using multiple laboratory and exterior exposures to calculate an acceleration factor is described by J. A. Simms (1).94.1.4 There are a number of factors that may decrease the degree of correlation between accelerated tests using laboratory light sources and exterior exposures. More specific information on how each factor may alter stability ranking of materials is given in Appendix X1.4.1.4.1 Differences in the spectral distribution between the laboratory light source and solar radiation.4.1.4.2 Light intensities higher than those experienced in actual use conditions.4.1.4.3 Test conditions where specimens are exposed continuously to light when actual use conditions provide alternate periods of light and dark.4.1.4.4 Specimen temperatures higher than those in actual conditions.4.1.4.5 Exposure conditions that produce unrealistic temperature differences between light and dark colored specimens.4.1.4.6 Exposure conditions that do not have any temperature cycling or that produce temperature cycling, or thermal shock, or both, that is not representative of use conditions.4.1.4.7 Unrealistically high or low levels of moisture.4.1.4.8 Absence of biological agents or pollutants.4.2 Use of Accelerated Tests with Laboratory Light Sources: 4.2.1 Results from accelerated exposure tests conducted according to this standard are best used to compare the relative performance of materials. A common application is conducting a test to establish that the level of quality of different batches does not vary from a control material with known performance. Comparisons between materials are best made when they are tested at the same time in the same exposure device. Results can be expressed by comparing the exposure time or radiant exposure necessary to change a characteristic property to some specified level.4.2.1.1 Reproducibility of test results between laboratories has been shown to be good when the stability of materials is evaluated in terms of performance ranking compared to other materials or to a control (2, 3); therefore, exposure of a similar material of known performance (a control) at the same time as the test materials is strongly recommended.4.2.2 In some applications, weathering reference materials are used to establish consistency of the operating conditions in an exposure test.4.2.3 Reference materials, for example, blue wool test fabric, also may be used for the purpose of timing exposures. In some cases, a reference material is exposed at the same time as a test material and the exposure is conducted until there is a defined change in property of the reference material. The test material then is evaluated. In some cases, the results for the test material are compared to those for the reference material. These are inappropriate uses of reference materials when they are not sensitive to exposure stresses that produce failure in the test material or when the reference material is very sensitive to an exposure stress that has very little effect on the test material.NOTE 5: Definitions for control and reference material that are appropriate to weathering tests are found in Terminology G113.NOTE 6: Practice G156 describes procedures for selecting and characterizing weathering reference materials used to establish consistency of operating conditions in a laboratory accelerated test.NOTE 7: Results from accelerated exposure tests should only be used to establish a pass/fail approval of materials after a specific time of exposure to a prescribed set of conditions when the variability in the exposure and property measurement procedure has been quantified so that statistically significant pass/fail judgments can be made.1.1 This practice covers general procedures to be used when exposing nonmetallic materials in accelerated test devices that use laboratory light sources. Detailed information regarding procedures to be used for specific devices are found in standards describing the particular device being used. For example, detailed information covering exposures in devices that use open flame carbon arc, enclosed carbon arc, xenon arc, and fluorescent UV light source are found in Practices G152, G153, G154, and G155 respectively.NOTE 1: Carbon-arc, xenon arc, and fluorescent UV exposures were also described in Practices G23, G26, and G53 which referred to very specific equipment designs. Practices G152, G153, and G154, and G155 are performance based standards that replace Practices G23, G26, and G53.1.2 This practice also describes general performance requirements for devices used for exposing nonmetallic materials to laboratory light sources. This information is intended primarily for producers of laboratory accelerated exposure devices.1.3 This practice provides information on the use and interpretation of data from accelerated exposure tests. Specific information about methods for determining the property of a nonmetallic material before and after exposure are found in standards describing the method used to measure each property. Information regarding the reporting of results from exposure testing of plastic materials is described in Practice D5870.NOTE 2: Guide G141 provides information for addressing variability in exposure testing of nonmetallic materials. Guide G169 provides information for application of statistics to exposure test results.NOTE 3: This standard is technically equivalent to ISO 4892, Part 1.1.4 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.
