100

The temperature at which a liquid changes its phase to a vapor or gas.

What is Boiling Point.

100

The range of gas or vapor concentration (percentage by volume in air) that will burn or explode if an ignition source is present.

What is Flammable (Explosive) Range.

100
Materials that react with water and release a flammable gas or present a health hazard. Some materials may also react explosively.
What is Water Reactivity.
100
Compound that forms hydrogen ions in water. These compounds have a pH <7.
What is an Acid.
100

The temperature at which a solid changes its phase to a liquid.

What is Melting Point.

200

The ability of a solid, liquid, gas, or vapor to dissolve in water or other specified medium.

What is Solubility.

200
Below this a mixture of gas or vapor is too lean to burn.
What is Lower Flammable Limit.
200
This is added to products to control their chemical reaction with other products.
What is an Inhibitor.
200
Compound that forms hydroxide ions in water. These compounds have a pH >7.
What is a Caustic (Base, Alkaline).
200
The ability of materials to dissolve into a uniform mixture.
What is Miscibility.
300
Measurement of the thickness of a liquid and its ability to flow.
What is Viscosity.
300

The minimum temperature required to ignite gas or vapor without a spark or flame being present.

What is Ignition (Autoignition) Temperature.

300
Materials that ignite spontaneously in air without an ignition source.
What is Pyrophoric Materials (Air Reactivity)
300
The degree to which a corrosive ionizes in water.
What is Strength.
300
The ability of a substance to change from the solid to the vapor phase without passing through the liquid phase.
What is Sublimation.
400

The weight of a solid or liquid material as compared with the weight of an equal volume of water.

What is Specific Gravity.

400

The minimum temperature at which a liquid gives off sufficient vapors the will ignite and sustain combustion.

What is Fire Point.

400
Used to control the rate of a chemical reaction by either speeding it up or slowing it down.
What is a Catalyst.
400
The percentage of an acid or base dissolved in water.
What is Concentration.
400
The weight of a pure vapor or gas compared with the weight of an equal volume of dry air at the same temperature and pressure.
What is Vapor Density.
500
The ease with which a liquid or solid can pass into the vapor state.
What is Volatility.
500

The minimum temperature at which a liquid gives off sufficient vapors that will ignite and flash over but will not continue to burn without the addition of more heat.

What is Flash Point.

500

A reaction during which a monomer is induced to polymerize by the addition of a catalyst or other unintentional influences, such as excessive heat, friction, contamination. If reaction is not controlled, it is possible to have an excessive amount of energy released become a violent reaction.

What is Polymerization.

500
The measurement of the hydrogen ion concentration in solution.
What is pH.
500
The pressure exerted by the vapor within the container against the sides of the container.
What is Vapor Pressure.
