JIS A 5362:2010 PDF Download

JIS A 5362:2010 standard specifies the required performance of precast concrete products and the methods to verify their performance. The standard does not apply to individual concrete products for buildings, as they are covered by separate Japanese Industrial Standards. The standard includes a comparison table of revisions between the previous and current editions.

The focus of the standard is primarily on specifying the performance of the products themselves. However, due to the nature of their usage, the performance of the structures for which the products are intended is also discussed in some sections of the standard. The relationship between products and structures can vary, as a product can be used as a standalone structure, as a part of a structure, or as a combination of several products to form a structure.

When designing the structure, the recommended sequence is first developing the structure design to meet certain requirements, and then designing and manufacturing the related products based on this structure design. The purchaser presents the performance requirements for both the structure and the product, and the producer designs and verifies the performance of the product and the structure before manufacturing them.

In practice, producers may design the products beforehand based on the general anticipation of how the structure and the product will be used. The producers then sell the manufactured products by identifying the recommended specification or organization standard by which the product's performance has been verified. In this case, the purchaser selects the product that satisfies the required performance of the structure from multiple choices of products.
