1.1 本试验方法包括液态水乳液地板抛光剂的贮存稳定性。 1.2 52℃储存30天 °C（125 °F），但不能保证在21 °C（70 °F），被认为是比持续时间更短的类似试验更可靠的储存稳定性指标。 注1: 通过试验方法测定的黑色玻璃60°镜面光泽度 第1455页 ，可用于确认该观察结果。老化和未老化样品之间光泽的显著差异表明不稳定。如果重复样品在52℃下保持30天不变，则可合理预期所述材料的货架稳定性为一年 °C±1.1 °C（125 °F±2 °F）。如果一个或两个副本显示粘度增加或轻微奶油化，则必须寻求其他稳定性证据。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 该试验方法不是绝对的，但确实表明了液态水乳液地板上光剂的有效保质期。将指示抛光剂在产品的预期储存期内是否会凝胶或保持可用液体。应注意，在相同的储存条件下，不同成分类型的抛光剂的有效储存寿命会有所不同。

1.1 This test method covers the storage stability of liquid water-emulsion floor polishes. 1.2 Storage for 30 days at 52 °C (125 °F), while not a guarantee of one year stability at 21 °C (70 °F), is believed to be a more reliable indicator of storage stability than similar tests of shorter duration. Note 1: The 60° specular gloss on black glass determined by Test Method D1455 , may be used to confirm this observation. A substantial difference in gloss between aged and unaged samples is an indication of instability. A shelf stability of one year can be reasonably expected of the material in question if duplicate samples remain unchanged for 30 days at 52 °C ± 1.1 °C (125 °F ± 2 °F). If one or both duplicates show more than slight viscosity increases or slight creaming, other evidence of stability must be sought. 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. ====== Significance And Use ====== 3.1 This test method is not absolute but does give an indication of the useful shelf-life of a liquid water-emulsion floor polish. Will indicate whether a polish will gel or remain a usable liquid over the desired storage life of the product. It should be noted that polishes of different composition types will vary in useful storage life under identical storage conditions.
