5.1 Despite child-resistant packaging requirements for most potentially harmful liquid consumer products, each year tens of thousands of young children are evaluated in emergency departments for potential poisoning from liquid consumer products. Products that use reclosable safety packaging rely on users to resecure the child-resistant closure fully after each use. If the closure is not fully secured or a child opens the closure, the entirety of the product contents is immediately accessible. Restricted delivery systems are a type of packaging for medications and other liquid consumer products designed to limit the amount of product that is accessible even after the primary closure is removed.5.2 This test method can be used to provide quantitative assessment of restricted delivery systems for liquid consumer products. This test method outlines three types of mechanical test procedures to simulate methods young children may use when attempting to access liquid contents from a container. To evaluate the efficacy of restricted delivery systems, tests are conducted with the primary closure removed and under conditions approximating intended use of the products. Instruction for use for the intended product should be used when preparing the samples for testing; for example, storage temperature, shaking of product, and use of associated dispensing devices when applicable.1.1 This test method covers assessment of non-metered restricted delivery system characteristics so that they can be evaluated to a standard that signifies efficacy in limiting accessibility of liquid contents to young children.1.2 This test method provides general test conditions for the determination of flow control of liquids by restricted delivery systems using mechanical testing to simulate methods that may be used to access liquid consumer products by young children.1.3 The test parameters provided within this test method are estimates based on existing literature and experience. The estimated values are intended to allow comparison of performance characteristics across different restricted delivery systems.1.4 This test method applies to liquids packaged in reclosable containers.NOTE 1: Since there are many variables that may affect release of liquid (for example, rigidity of container, viscosity of liquid contents, or variation in test equipment), it is important that the entire restricted delivery system is tested together as intended for use while using the same or similar testing equipment. This test method does not address other product characteristics that might be affected by use of restricted delivery systems (for example, uniformity of active ingredient throughout duration of use).1.5 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 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 for testing cotton for non-lint content is considered satisfactory for acceptance testing of commercial shipments since it is the best available procedure for obtaining objective data.5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, ensure the test samples to be used are as homogeneous as possible, are drawn from the material from which the disparate test results were obtained, and are randomly assigned in equal numbers to each laboratory for testing. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.5.2 This test method gives data on the non-lint content of raw cotton which can be used as a basis for: (1) estimating the net amount of manufactured textile product obtainable from raw cotton; (2) predicting the quality of cotton textile products, particularly their aesthetic properties; (3) assembling and blending bales in a mix on a non-lint content basis; (4) adjusting ginning and textile processing machines for maximum efficiency in cleaning lint; and (5) relating non-lint content of cotton to end-product quality and processing efficiency.1.1 This test method covers the determination of the non-lint content of cotton using the Shirley Analyzer. The cotton may be in the form of (1) raw stock, that is, cotton fiber that has been separated from the seed by ginning; (2) partially processed cotton, such as picker lap or sliver; or (3) ginning or processing waste, such as obtained from ginning, opening and cleaning, picking, carding, or combing machines.1.2 This test method is especially adapted for determining non-lint content of cotton by use of the Shirley Analyser.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. 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 hazard statements, see Section 7.1.5 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.
