In many countries, the labeling is altogether different. In the UK, for example, 'grades' might be called 'years' as in Year 1, Year 2, and so on. So, the following list of ages by grade levels is based on the United States but should roughly apply to the formal education system for most countries.

Report Highlights: Vietnam's coffee sector is in the midst of trying to apply new grading standards. Although the new system was developed for use in the 2002/2003 coffee crop, few Vietnamese exporters or foreign importers seem interested in using the new standards. Vietnam's 2001 and 2002 production by province data area also provided.
Characteristics. Anthracite contains a high amount of fixed carbon—80 to 95 percent—and very low sulfur and nitrogen—less than 1 percent each. Volatile matter is low at approximately 5 percent, with 10 to 20 percent ash possible. Moisture content is roughly 5 to 15 percent. The coal is slow-burning and difficult to ignite because of its ...
Anthracite is the highest rank of coal. Unlike other types of coal, it is usually considered to be a metamorphic rock. It has a carbon content of over 87% on a dry ash-free basis. Anthracite coal generally has the highest heating value per ton on a mineral-matter-free basis. It is often subdivided into semi-anthracite, anthracite, and meta ...
Anthracite is the final stage of coal, meaning it's the hardest and has the highest energy density of them all. Due to anthracite being the final stage of coal, it means that it has the lowest moisture content of around 4% and the highest carbon content of <90%. This results in a slow combustion process, giving off a significant heating value.

Ans. Anthracite coal can mainly be classified into three separate grades depending on its quality and carbon content. These 3 grades are – Ultra-High Grade, High Grade and Standard Grade. The Ultra-High and High-Grade Anthracite coal is the purest variety of coal available and they find extensive use in metallurgy and steel making.
Anthracite coal is categorized into three types of grades. These are (i) semi-anthracite or standard grade, (ii) anthracite or high grade, and (iii) meta-anthracite or ultra-high …

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, …
