1.1 本规范涵盖了用于覆盖水硬性水泥混凝土表面的片状材料，以抑制养护期间的水分损失，对于白色反射型材料，还可减少暴露在太阳辐射下的混凝土的温升。包括以下类型: 1.1.1 固化纸: 1.1.1.1 有规律的 1.1.1.2 白色 1.1.2 聚乙烯薄膜: 1.1.2.1 清楚的 1.1.2.2 白色不透明。 1.1.3 白色粗麻布聚乙烯板。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 注1: 本规范不包括用于额外加水以保持水分的粗麻布、棉垫或地毯等材料- 此类表面上的饱和环境。具有额外特性（例如绝缘性能和将额外水输送到固化区域的能力）的板材可在市场上买到，但本规范目前未涉及。 1.3 本标准的文本引用了提供解释材料的注释和脚注。这些注释和脚注不应视为本标准的要求。 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers materials in sheet form used for covering the surfaces of hydraulic cement concrete to inhibit moisture loss during the curing period and, in the case of the white reflective type materials, to also reduce temperature rise in concrete exposed to radiation from the sun. The following types are included: 1.1.1 Curing Paper: 1.1.1.1 Regular. 1.1.1.2 White. 1.1.2 Polyethylene Film: 1.1.2.1 Clear. 1.1.2.2 White Opaque. 1.1.3 White-Burlap-Polyethylene Sheet. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Note 1: This specification does not cover materials such as burlap, cotton mats, or rugs used with additional applications of water to maintain a water-saturated environment on such surfaces. Sheet materials having additional characteristics such as insulating properties and the ability to carry additional water to the curing region are commercially available but are not currently addressed in this specification. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard. 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.
