4.1 This guide establishes the minimum requirements for training SWFT-Basic personnel. A person trained to this guide is considered to be a SWFT-Basic.4.2 Every person who is identified as a SWFT-Basic shall have met the requirements or equivalent of this guide.4.3 This guide is to be used by the individuals and Authorities Having Jurisdiction (AHJs) that wish to identify the minimum training required for SWFT-Basic. No advanced skills are included or implied.4.4 This guide was developed specifically for use in the United States, but may be used in other countries as needed.4.5 This guide should be used in conjunction with established and authorized guidelines and procedures mandated by the AHJ.4.6 Nothing in this guide precludes an AHJ from adding additional requirements for its own members.4.7 The AHJ shall determine that personnel, agencies, and organizations are qualified and authorized to participate in swiftwater/flood search and rescue operations.4.8 The AHJ shall determine the evaluation process used to assess the extent to which the requirements of this guide are met.4.9 Swiftwater personnel should only perform activities in the swiftwater environment after a thorough risk assessment and appropriate risk mitigation efforts (such as the use of personal protective equipment (PPE), restricting efforts to shore-based techniques, or delaying a recovery until more favorable water conditions exist) have been performed. At the very least, personnel should follow the appropriate national, federal, state, tribal, provincial, and local safety standards as they apply to activities in swiftwater environments. SWFT-Basic personnel should be supervised by a Swiftwater/Flood Rescue Technician-Intermediate (SWFT-Intermediate) or Swiftwater/Flood Rescue Technician-Advanced (SWFT-Advanced) for in-water rescue operations. Shore-based rescue does not necessarily require SWFT-Intermediate or SWFT-Advanced supervision, but any rescue requires appropriate command and control, determined by the level of complexity. Rescue shall be done using the appropriate safety precautions.1.1 This guide establishes the areas of expertise that Search and Rescue (SAR) Swiftwater/Flood Rescue Technician Basic (SWFT-Basic) personnel shall demonstrate in order to perform in, on, or around a swiftwater environment.1.1.1 Specifically, this guide defines the recommended training required to prepare SWFT-Basic personnel, or equivalent, for responding to or conducting shore-based swiftwater and flood rescue operations.1.1.2 This guide establishes the general areas of expertise that SWFT-Basic personnel shall demonstrate. This guide does not cover specialized types of swiftwater/flood SAR, such as helicopter and boat-based rescues.1.1.3 This guide also establishes the minimum training requirements.1.2 This is the entry-level position for swiftwater/flood responders.1.3 SWFT-Basic personnel shall be able to recognize, reduce, eliminate, or mitigate, within the scope of their training, the hazards and risks in a swiftwater or flood situation or environment and be able to request appropriate additional resources.1.4 This guide identifies types of rescues, tactics, and systems that are typically used by SWFT-Basic personnel, such as shore-based rescues using talking, reaching, throwing, and wading methods.1.5 SWFT-Basic personnel who have met the minimum qualifications and experience within this guide are capable of performing shore-based rescues and assisting with in-water rescues from the shore under qualified supervision.1.6 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 gauge is intended to provide a means for measuring image or detector unsharpness and basic spatial resolution of the image or detector as independently as practicable from the imaging system and contrast sensitivity limitations. When the duplex gauge is positioned directly on the film or the digital detector and not on the test object, then the determined unsharpness corresponds to the inherent film or detector unsharpness (Udetector) and the determined basic spatial resolution corresponds to the basic spatial detector resolution SRbdetector.NOTE 1: The gauge, described in ISO 19232-5, is equivalent to this standard in the dimensions and the evaluation procedure.5.2 Basis of Application 5.2.1 The following items are subject to contractual agreement between the parties using or referencing this practice.5.2.1.1 Personnel Qualification—Personnel performing examinations to this practice shall be qualified in accordance with NAS410, EN 4179, ANSI/ASNT CP 189, ISO 9712, or SNT-TC-1A and certified by the employer or certifying agency as applicable.

4.1 This practice provides approaches for characterizing a sample of n observations that arrive in the form of a data set. Large data sets from organizations, businesses, and governmental agencies exist in the form of records and other empirical observations. Research institutions and laboratories at universities, government agencies, and the private sector also generate considerable amounts of empirical data.4.1.1 A data set containing a single variable usually consists of a column of numbers. Each row is a separate observation or instance of measurement of the variable. The numbers themselves are the result of applying the measurement process to the variable being studied or observed. We may refer to each observation of a variable as an item in the data set. In many situations, there may be several variables defined for study.4.1.2 The sample is selected from a larger set called the population. The population can be a finite set of items, a very large or essentially unlimited set of items, or a process. In a process, the items originate over time and the population is dynamic, continuing to emerge and possibly change over time. Sample data serve as representatives of the population from which the sample originates. It is the population that is of primary interest in any particular study.4.2 The data (measurements and observations) may be of the variable type or the simple attribute type. In the case of attributes, the data may be either binary trials or a count of a defined event over some interval (time, space, volume, weight, or area). Binary trials consist of a sequence of 0s and 1s in which a “1” indicates that the inspected item exhibited the attribute being studied and a “0” indicates the item did not exhibit the attribute. Each inspection item is assigned either a “0” or a “1.” Such data are often governed by the binomial distribution. For a count of events over some interval, the number of times the event is observed on the inspection interval is recorded for each of n inspection intervals. The Poisson distribution often governs counting events over an interval.4.3 For sample data to be used to draw conclusions about the population, the process of sampling and data collection must be considered, at least potentially, repeatable. Descriptive statistics are calculated using real sample data that will vary in repeating the sampling process. As such, a statistic is a random variable subject to variation in its own right. The sample statistic usually has a corresponding parameter in the population that is unknown (see Section 5). The point of using a statistic is to summarize the data set and estimate a corresponding population characteristic or parameter, or to test a hypothesis.4.4 Descriptive statistics consider numerical, tabular, and graphical methods for summarizing a set of data. The methods considered in this practice are used for summarizing the observations from a single variable. The descriptive statistics described in this practice are: mean, median, min, max, range, mid range, order statistic, quartile, empirical percentile, quantile, interquartile range, variance, standard deviation, Z-score, coefficient of variation, and skewness and kurtosis.4.5 Statistical inference is drawing conclusions about the population or its parameters. Methods for statistical inference described in this practice are: degrees of freedom, standard error, confidence intervals, prediction intervals, tolerance intervals, and statistical hypothesis tests.4.6 Tabular methods described in this practice are: frequency distribution, relative frequency distribution, cumulative frequency distribution, and cumulative relative frequency distribution.4.7 Graphical methods described in this practice are: histogram, ogive, boxplot, dotplot, normal probability plot, and q-q plot.4.8 While the methods described in this practice may be used to summarize any set of observations, the results obtained by using them may be of little value from the standpoint of interpretation unless the data quality is acceptable and satisfies certain requirements. To be useful for inductive generalization, any sample of observations that is treated as a single group for presentation purposes must represent a series of measurements, all made under essentially the same test conditions, on a material or product, all of which have been produced under essentially the same conditions. When these criteria are met, we are minimizing the danger of mixing two or more distinctly different sets of data.4.8.1 If a given collection of data consists of two or more samples collected under different test conditions or representing material produced under different conditions (that is, different populations), it should be considered as two or more separate subgroups of observations, each to be treated independently in a data analysis program. Merging of such subgroups, representing significantly different conditions, may lead to a presentation that will be of little practical value. Briefly, any sample of observations to which these methods are applied should be homogeneous or, in the case of a process, have originated from a process in a state of statistical control.4.9 The methods developed in Sections 6, 7, 8, and 9 apply to the sample data. There will be no misunderstanding when, for example, the term “mean” is indicated, that the meaning is sample mean, not population mean, unless indicated otherwise. It is understood that there is a data set containing n observations. The data set may be denoted as:4.9.1 There is no order of magnitude implied by the subscript notation unless subscripts are contained in parenthesis (see 6.7).AbstractThis practice covers methods and equations for computing and presenting basic statistics. This practice includes simple descriptive statistics for variable and attribute data, elementary methods of statistical inference, and tabular and graphical methods for variable data. Some interpretation and guidance for use is also included.This practice provides approaches for characterizing a sample of n observations that arrive in the form of a data set.
