Standard sieve (standard sieve)

Japanese: 標準ふるい(標準篩) - ひょうじゅんふるい(英語表記)standard sieve
Standard sieve (standard sieve)
Among sieves made of metal mesh or metal perforated plates for measuring particle size distribution, those that comply with the standards prescribed in the Japanese Industrial Standards (JIS Z 8801). For mesh sieves, the mesh size is specified to be from 125 mm to 22 μm in nominal dimensions, following the R40/3 sequence, and for perforated plates (plate sieves), the mesh size is specified to be from 125 mm to 5 mm in nominal dimensions, following the R20 sequence. As JIS Z 8801 is called Test Sieves in English, this standard sieve is mainly intended for testing purposes, and there are several standards for Test Sieves both internationally and at the International Organization for Standardization (ISO), and industrial standards in each country are generally set along these lines.

Japanese:
金属網,あるいは金属多孔板でつくられた粒度分布測定用のふるいのうち,日本工業規格〈JIS Z 8801〉で規定された基準に従ったものをいう。ふるいの目開きは,網ふるいについては呼び寸法で125mmから22μmまで,R40/3数列に従った目開きが,多孔板(板ふるい)については呼び寸法が125mmから5mmまでR20の数列に従った目開きが規定されている。JIS Z 8801は英文ではTest Sieves(試験用ふるい)としているように,この標準ふるいは主として試験用を目的とするものであって,国際的にも国際標準化機構(ISO)でもTest Sievesに関する数種の規格があり,各国の工業規格もほぼその線に沿って定められている。
