This consumer safety specification establishes the design requirements for the corner post extensions of full-size and non-full-size baby cribs to minimize the potential for strangulation of infants and young children who may attempt to climb out of the crib. It also provides the required information to be included in the instructions furnished with these cribs regarding the potential hazards to children wearing pacifiers, necklaces, or any other items around their necks.1.1 This consumer safety specification establishes design requirements for corner posts of full-size and non-full-size baby cribs (Note 1) to minimize the potential for strangulation of infants and young children who may attempt to climb out of the crib. It also provides information in the instructions furnished with cribs of the potential hazard to children wearing pacifiers, necklaces, or any other items around their necks.Note 1-The terms "full-size" and "non-full-size" cribs are those used in the mandatory requirements for these products that were promulgated by the U.S. Consumer Product Safety Commission and published in the Code of Federal Regulations as 16 CFR Parts 1508 and 1509.

5.1 Due to hydraulic pressure that may be present on some applications, engineers need to understand the capability of these products to resist this pressure. This test allows engineers to compare products and verify pullout strength.5.2 Hydraulic pullout resistance is a function of locking extension dimensions, locking extension geometry, locking extensions per area, locking extension polymer composition, and the properties of the concrete in which the locking extensions are embedded.5.3 The data from this test method provides comparative information for rating hydraulic pullout resistance of different geomembranes with locking extensions embedded in concrete. Hydraulic pullout resistance, while partly dependent on locking extension dimensions, has no simple correlation to locking extension dimensions and geometry. Hence, hydraulic pullout resistance cannot be determined with a small sample without potentially producing misleading data to the actual hydraulic pullout resistance of the material. Therefore, the hydraulic pullout resistance is expressed in kPa (lb/ft2).5.4 The apparatus can be circular or square in nature and must have a test area of 0.36 m2 (558 in.2).5.5 Fig. 1 shows an example of a circular test apparatus that can be used in the performance of this test. The apparatus requires a pressure vessel rated to a minimum 690 kPa (14 410 lb/ft2). The vessel test diameter should be a minimum of 677.04 mm (26.655 in.) as shown in Fig. 1.FIG. 1 Picture of Circular Test ApparatusNOTE 1: Larger vessels may be used but it is up to user to establish correlation to the standard size vessel. The use of a smaller diameter vessel than denoted in this standard may contribute to higher pullout resistance due to thickness or stiffness of some products.5.6 Test Pedestal—The base of the testing apparatus which holds the test specimen.5.7 Upper Flange—Is the flange that is bolted down on top of specimen to create a seal.5.8 Form—Is an aluminum ring used to form test specimen as shown in Fig. 2.FIG. 2 Bottom of Form with Studs Facing Up and Cylinder Spacer5.9 Specimen Ring—The solid ring that is placed around test specimen to contain leakage through the concrete.5.10 The vessel will have a system to measure pressure.5.10.1 The system for measuring pressure shall be capable of being read to an accuracy of 3.5 kPa (0.5 psi).5.11 Concrete shall be a ready-mixed concrete per Specification C94/C94M with a minimum cured compressive strength of 34 473.8 kPa (5 000 psi).NOTE 2: Alternate concrete or grout mixtures may be used for project-specific applications with the approval of the owner or engineer.5.12 All tests shall be conducted at standard laboratory temperatures of 23 ± 2 °C (73.4 ± 3.6 °F).1.1 This test method covers the determination of the hydraulic pullout resistance of a geomembrane with locking extensions embedded in concrete by determining the pressure required for locking extensions of the embedded specimen to pullout of the concrete.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses 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.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.
