This document modifies and adopts ISO 7171.2019 Furniture - Storage Units - Test Methods for the Determination of Stability. In comparison with ISO 7171.2019, this document makes the following structural adjustments. ---The content of 6.1 in ISO 7171.2019 is integrated into 4.1 of this document; ---The content of Appendix A in ISO 7171.2019 is divided into Appendix A and Appendix B of this document; ---Appendix C corresponds to Appendix B of ISO 7171.2019. The technical differences between this document and ISO 7171.2019, and the causes for these differences are as follows. ---The expression of the Scope is modified to comply with the compilation regulations of Chinese Standards (see Chapter 1; Chapter 1 of ISO 7171.2019); ---The terms and definitions of overturn, TV-furniture and bracket are added for the newly added related test items (see 3.1; 3.3 and 3.4); ---The terms and definitions of extension element, flap, free standing unit, interlock, leveling device, unit, clear height, locking mechanism, worst case, suspended filing pockets, wall attachment device and component are deleted, because they have been included in GB/T 10357.5 (see Chapter 2 of ISO 7171.2019); ---The pre-treatment requirements are modified, and the provisions for connecting walls and failing to satisfy test conditions are added. The test items of the product are clarified, and deviation assessment is proposed, which is more operable (see 4.1; 4.1 of ISO 7171.2019); ---The requirements for dimensional tolerances are modified. dimensions smaller than 200 mm are distinguished from the requirements for other dimensional tolerances, and the requirements for dimensional tolerances of the spherical curvature of a radius of 300 mm on the loading pad are added. Different tolerance requirements are proposed for different dimensions, which is more scientific (see 4.3; 4.3 of ISO 7171.2019); ---The loading provisions for storage components / volumes of heavy equipment (such as. refrigerators and washing machines) are added. More storage situations for storage units are covered, which is more complete (see Table 1 of 4.5); ---The requirements for test facilities, such as. wall surfaces, spherical objects and TV formworks, etc. are added, which are required for the newly added test items (see 5.3, 5.7 and 5.9); ---Partial loading test of storage components is added, and the content of this part is added to Appendix C, so as to ensure the stability of this type of products (see 6.4.4); ---Additional stability test for TV-furniture is added, so as to ensure the stability of this type of products (see 6.8); ---Appendix A is modified, so as to facilitate the understanding of the principle of applied force selection (see Appendix A); ---The load and force of the stability test of storage units are modified and divided into two recommended levels for household and non-household purposes; the recommended levels of some tests in different service environments are also sub-divided, and the content of this part is adjusted to be normative, which is more reasonable (see Appendix B; Appendix B of ISO 7171.2019). This document makes the following editorial modification. ---The title of the Standard is modified, so as to maintain consistency with the titles of other parts of GB/T 10357.
