Answer :
Final answer:
The ASTM D4727 industry standard divides fiberboard into corrugated and solid fiberboard, specifying guidelines for these materials. Corrugated fiberboard is commonly used in packaging, while solid fiberboard is used in various applications such as construction.
Explanation:
The ASTM D4727 industry standard classifies fiberboard into two main categories: corrugated and solid fiberboard. Corrugated fiberboard is a material consisting of a fluted corrugated sheet and one or two flat linerboards. It is widely used in the packaging industry due to its lightweight and sturdy nature. Solid fiberboard, on the other hand, is a versatile material made from compressed layers of paper or paperboard and is used for a variety of applications, including construction and furniture making. The ASTM standards provide guidelines on quality and specifications for materials used in different industries.
Fiberboard materials can also include other fibers such as boron, carbon, silicon carbide, and alumina, which are covered under different subsections of the ASTM standards, depending on their specific properties and uses. These advanced materials are commonly utilized in high-performance applications where strength, durability, and light weight are crucial. It is important to note that each type of fiber has its own unique characteristics and applications, and the ASTM standards are there to ensure consistency and quality across materials used in industry.
Final Answer:
The ASTM D4727 standard does not classify fiberboard into corrugated and non-corrugated categories; it focuses on dynamic water resistance testing for fabrics. Corrugated fiberboard is often associated with other ASTM standards, but D4727 is not one of them.
Explanation:
The ASTM D4727 standard pertains to the dynamic water resistance testing of fabrics and does not provide classification for fiberboard into corrugated and non-corrugated categories. This standard is specific to evaluating the ability of fabrics to resist water under dynamic conditions, and its scope does not extend to fiberboard characterization.
Corrugated fiberboard, commonly used in packaging, involves a structural design with a corrugated inner layer flanked by flat outer layers. While ASTM standards play a crucial role in defining and assessing the properties of various materials, including fiberboard, D4727 is not directly related to this specific classification.
For standards related to fiberboard, ASTM D4729 and ASTM D4728 are more pertinent. ASTM D4729 addresses the performance of fiberboard containers and ASTM D4728 focuses on the testing of fiberboard properties, such as thickness, density, and moisture content. These standards contribute to ensuring the quality and suitability of fiberboard for diverse applications beyond the scope of the ASTM D4727 fabric water resistance test.
