ASTM C – 00 Standard Specification for Aggregate for Job-Mixed Portland Cement-Based Plasters
The fineness modulus, friable particles, light constituents, organic impurities, material soundness, and sieve analysis of the aggregate shall be tested to meet the requirements prescribed. We astj users of early versions of Internet Explorer to update to Version 10 or later. ASTM C is currently being specified a lot for interior basecoat plaster in Federal government work.
The values given in parentheses are zstm conversions to SI ast that are provided for information only and are not considered standard. Aggregate subjected to five cycles of the soundness test shall show a loss, when weighed in accordance with the grading of a sampling complying with the limitations set forth.
Aggregate subjected to five cycles of the soundness test shall show a loss, when weighed in accordance with the grading of a sampling complying with the limitations set forth.
This chart is completely ambiguous if you do the math, but the idea is that the sand is graded from coarse down to fine powder.
This specification covers d897 or manufactured aggregate for use in job-mixed base and finish-coat full thickness Portland cement, Portland cement-lime and modified Portland cement plasters.
These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the specification. Distribution of the PDF is not permitted. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

The reason is that the smaller grains fill in the voids when the mortar is packed down. This specification covers natural or manufactured aggregate for use in job-mixed base and finish-coat full thickness Portland cement, Portland cement-lime and modified Portland cement plasters.

What this means in human readable terms: I know somebody out west who plasters boats. Number two is all mediumand number 1 is all fine.
The breaking strength of these boats was well over 10, PSI. The main difference is that number 3 is all the same size about 3 mm.
The fineness modulus, friable particles, light constituents, organic impurities, material soundness, and sieve analysis of asfm aggregate shall be tested to c87 the requirements prescribed.
