Amount of water in a material determined under prescribed conditions, and expressed as a percentage of the mass of the moist specimen, that is, the mass of the dry substance plus the water present.
the percentage of water in pulp, paper or paperboard
MC is the weight of the water within a piece of lumber measured as a percentage of the weight of the dry wood. Most hardwoods manufactured in the United States are produced to standards developed by the National Hardwood Lumber Association (NHLA). Moisture content in wood prepared for interior use in North America is typically 6-9%.
This is the amount of a liquid eg water, oil, solvent, etc, that is contained within a dry solid material, usually expressed in percent.
the measure of relative humidity in paper - this affects the stability of the paper.

The amount of moisture in paper, normally ranging from 5% to 8%. Paper easily picks up or emits moisture to and from the surrounding environment.
The amount of moisture in wood expressed as a percentage of the weight of the oven dry wood. National Oak Flooring Manufacturers Association hardwood flooring is manufactured at 6% to 9% moisture content, with a 5% allowance for pieces up to 12% moisture content. American Parquet Association parquet flooring is to be 7% to 11% moisture content at time of shipment. 5% of the flooring may be outside of this range.
The amount of moisture trapped in the cells of the wood. Moisture levels for air-dried wood vary according to region. In Arizona, air-dried hardwood may reach 6 percent, in New England about 12 to 15 percent. Generally, hardwoods in the U.S. are dried to 7 to 9 percent moisture content.
The amount of water a lubricant can absorb. It is measured in part per million (ppm).
The amount of moisture in paper, pulp, pulpboard, chips, etc., that varies according to atmospheric conditions.
The amount of water within tobacco leaves. High moisture content gives the leaves elasticity, whereas low moisture content makes the leaves brittle. For this reason, the moisture content of tobacco is carefully controlled so that handling, storing, and manufacturing does not detract from the tobacco's quality or cause it to break into smaller, less desirable pieces. Moisture content is essential to the fermentation process.

Weight of the water within a piece of lumber measured as a percentage of the weight of the dry wood. Typical moisture content for kiln dried construction lumber is 15%. Wood absorbs or gives off moisture depending on the ambient moisture in the air. The percentage of wood that is not moisture is referred to as "dry solids," that is, dried construction lumber would be 85% dry solids. Product standards for lumber manufactured in the United States are developed under the jurisdiction of the U.S. Department of Commerce and administered by the American Lumber Standards Committee (ALSC). Members of the ALSC are representatives of various softwood lumber trade associations. As specified in the ALSC American Softwood Lumber Standard, softwood lumber is sold as "dry" if at a moisture content of 19% or less. Most hardwoods manufactured in the United States are produced to standards developed by the National Hardwood Lumber Association (NHLA). No single moisture content, however, is specified for hardwoods because the uses are more specialized. The moisture content must be specified by the buyer and agreed to by the seller; a 10% moisture content specification is common.
The amount of water in food.
The weight gain percent of a composite when exposed to saturated water vapor for extended periods.
The amount of water in the material, expressed as a percentage of the dry weight.
How much water or humidity is absorbed into the flooring.
The percent of moisture found in paper or pulp.
The amount of moisture an object possesses.
The amount of water contained within wood, most commonly as the percentage weight of water relative to the over-dry weight of the wood. Water contained within the wood may be ‘free water’ found between wood cells or ‘bound water’ found within the cell walls. Drying of wood does not result in significant shrinkage until all free water has been removed. The point at which no free water remains and shrinkage begins is known as the fiber saturation point (FSP), which occurs at about 28 percent moisture content.
The level of moisture (usually expressed as the percentage of moisture in the total sheet) in containerboard affects such properties as printability, shrinkage, dimensional stability (warp) and physical strength.
The percent by weight of moisture in a sheet of paper; varies in paper according to atmospheric relative humidity conditions, because the paper may either absorb or emit moisture, in an attempt to reach equilibrium.

This is the measure of the amount of water in a piece of wood. Green wood (see above), has a much higher moisture content than older dead wood.
The weight of the water in wood expressed in percentage of the weight of the oven-dry wood.
The fraction or percentage of a substrate comprised of water.
The amount of moisture in a printed sheet, which may range from 4% to 8%. Paper may emit or absorb moisture, and this can affect paper curl, static build-up and runnability in copier and printer papers.
(MC) The weight of the water contained in wood, usually expressed as a percentage of weight, either oven-dry or as received.

The amount of moisture in paper. It is expressed as a percentage of its weight. Typically, a moisture content of around 7-8% is recommended for printing on paper.
This is the total amount of water contained in a piece of wood. In timber technology, moisture content is expressed as a percentage of the oven dry weight. Moisture content determinations with the oven drying method give an average moisture content for the piece; actual moisture contents at different locations within this piece may vary quite considerably depending on the moisture gradient and drying characteristics of the particular timber species.
Refers to the amount of moisture found in a sheet of paper. Average amount ranges from 4-7%. This figure varies from sheet to sheet since paper will emit or absorb moisture according to the condition of the surrounding atmosphere. It is affected by both the drying conditions when made and the relative humidity environment in which it is used. The amount of water in a sheet of paper affects basis weight, printability, physical strength, and runnability. Moisture loss is realized in the form of shrinkage, which begins at the edges of paper and moves across the grain causing the sheet to tighten, wrinkle and curl.
The moisture content in wood or other biomass fuels is commonly expressed on a "wet basis." Moisture content on a wet basis (or MCWB) refers to the proportion of the total weight of a given quantity of wood that is actually water. For example, if green wood has a moisture content of 45 percent MCWB, then 45 percent of the total weight is water and 55 percent of the total weight is wood.
The weight of moisture contained in a piece of timber expressed as a percentage of the oven dry weight
The percentage by weight of water contained in the pore space of soil, sand or base, with respect to the weight of the solid material.
The amount of water contained in wood, expressed as a percentage that indicates the relative weight of the water in the piece compared to the oven dry weight. The optimum moisture content of wood for interior use is between 5-13% depending on the part of the country.
Sometimes abbreviated as MC. This is the amount of water contained in wood, usually expressed as a percentage of the weight of the oven dry wood.
The amount of water contained at the time of sampling expressed as a percentage of the total absorption.
The amount of moisture in wood expressed as a percentage of the weight of the oven dry wood. The nationally accepted standard for hardwood flooring is 6% to 8% moisture content, and up to 12% moisture allowed in 5% of the wood. Parquet flooring tile is to be 7% to 11% moisture content at time of shipment. 5% of the flooring may be outside of this range.
Percentage by weight of water in wood.
A measure of the amount of water in a piece of lumber.
Refers to the amount of moisture found in a sheet of paper. Average amount ranges from 5 to 8%. This figure varies from sheet to sheet since paper will emit or absorb moisture according to the condition of the surrounding atmosphere. Moisture loss is realized in the form of shrinkage which begins at the edges of paper and moves across the grain causing the sheet to tighten and curl. For explanation of the test to determine the moisture content of paper, see Chapter 6.
