Pulse amplitude modulated.

A state of matter in which similar or dissimilar solid or liquid substances exist in the form of aggregated molecules or particles. Airborne particulate matter is typically in the size range of 0.01 to 100 micrometers (micron).

A suspension of fine solid or liquid particles in air, such as dust, fog, fume, mist, smoke, or sprays. Particulate matter suspended in air is commonly known as an aerosol.

A form of business ownership made up of two or more people. Partners share an agreed upon percentage in the responsibility, profits, and/or losses of their business.

Any microorganism capable of causing disease.

Having the ability to produce or cause a disease.

These are the conditions you negotiate for payment of your invoices, such as "net 30" (or payment due in 30 days).

Personal computer or programmable controller.

Printed Circuit Board.

Pulse code modulation.

Pulse duration modulation.

Protocol data unit.

When a foreign contract is signed, a guarantee for good fulfilment could be requested by the exporter. Your financial institution or the supporting agency for exports expansion can help you to finance it.

Obligation from the bank or from the supplier's insurance company for guaranteeing to the purchaser the good execution of the contract by the supplier according to the contract's terms and conditions. This procedure will compensate the purchaser if the supplier does not fulfil his obligations. It usually corresponds to 10% of the value of the contract. 

An exposure limit is published and enforced by OSHA as legal standard.

A guarantee to the lender that you will take personal responsibility for repaying the loan or any other debt obligation.

Process flow diagram.

Means used to express the degree of acidity or alkalinity of a solution with neutrality indicated as seven.

An indication of the acidity or alkalinity of a solution. Units range from 0 (most acidic), to 7 (neutral), to 14 (most alkaline).

The number of individual voltages applied to an AC motor. A single-phase motor has one voltage in the shape of a sine wave applied to it. A three-phase motor has three individual voltages applied to it. The three phases are at 120 degrees with respect to each other so that peaks of voltage occur at even time intervals to balance the power received and delivered by the motor throughout its 360 degrees of rotation.

A class of resins produced as the condensation product of phenol or substituted phenol and formaldehyde or other aldehydes.

Certificate issued by the Department of Agriculture in order to meet the regulation on foreign products importation. The goods are examined and certified that they don't contain harmful insects or plant diseases.

Peripheral interface adaptor.

Robbery of part of a parcel contents.

A detector for transmitting the static and dynamic pressure of a moving fluid stream. The difference in the measured pressures is used to determine the velocity of the fluid.

A device used to measure total and static pressures in an airstream.

A device consisting of two concentric tubes, one serving to measure the total or impact pressure existing in the airstream, the other to measure the static pressure only.

Programmable logic controller.

Programmable logic device.

A supply system of ventilation that provides air at a positive pressure.

A method of braking a motor that involves applying partial or full voltage in reverse in order to bring the motor to zero speed.

Preventive maintenance.

A measure of total suspended particulate that is less than 10 microns in diameter.

As applied to electric circuits, polarity indicates which terminal is positive and which is negative. As applied to magnets, it indicates which pole is North and which pole is South.

A class of chemicals usually with four or more chlorine atoms per molecule and regulated under TSCA (Toxic Substance Control Act).

A class of chlorinated organic chemicals found at very low levels in combustion sources.

A class of chlorinated organic chemicals found at very low levels in combustion sources.

The interconnected facilities of an electrical utility. A power system includes the generation, transmission, distribution, transformation, and protective components necessary to provide service.

Programmed peripheral interface.

Parts per million.

A coil used to raise the outside air temperature above freezing, generally to 35°F.

Process of raising the temperature.

The normal force exerted by a homogeneous liquid or gas, per unit of area, on the wall of its container.

Force exerted per unit area.

Pressure loss in fluid pressure, as from one end of a duct to the other, due to friction, dynamic losses, and changes in velocity pressure.

The term used in the register industry to indicate how much total pressure is required to move air through a register.

A device, when installed in a fluid line, providing an analog output (4-20mA or 0-10V) proportional to the pressure being measured.

Ventilation achieved by overpressurising the building with exfiltration/natural exhaust. (used for very large buildings)

A method of testing for air leakage of a building or component by installing a powerful fan in the building envelope, e.g. through a door or window, and creating a static pressure excess inside the building. The flow rate through the fan and pressure difference across the envelope are measured and air leakage assessed.

Primary air fans (PA fans) are used for controlling airflow into a pulverizer (used to grind coal). The air amount and velocity will help in the combustion of fuel for the steam-generating boiler. The air drawn from the air heater is usually in a temperature range between 400 degrees and 700 degrees F, depending upon the size of the boiler. The operating temperatures of the PA fans will require thermal insulation for heat conservation and may also require acoustical sound and noise protection.

Invoice issued by the supplier before goods shipment, in which the purchaser is informed about the nature, the quantity, the commercial value and other details (such as weight, dimensions, etc.)

Temporary invoice established by the exporter before goods shipment indicating the products to be delivered, its value and other details.

The first temporary invoice issued by the exporter and addressed to the importer before shipping. This document informs the importer about the nature and the quantity of the goods, their estimated price plus other characteristics (weight, size, etc…). On the basis of these information, the importer will decide whether he wants to confirm or not his order.

A device for measuring airflow usually having about 8 flat inclined slightly after the manner of an airscrew, mounted on a horizontal axis.

Pounds per square inch.

Pounds per square inch, absolute.

A graphical representation of the thermodynamic properties of moist air.

An organism that grows optimally within the temperature range of 32°F to 68°F (0°C to 20°C).
