Divisions. Class 3: Flammable Liquids. A flammable liquid is a liquid having a flash point of not more than 60 °C (140 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging.
A flammable liquid is a liquid which can be easily ignited in air at ambient temperatures, i.e. it has a flash point at or below nominal threshold temperatures defined by a number of national and international standards organisations.
Combustibility and flammability. A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures.
This division includes compressed gas, liquefied gas, pressurized cryogenic gas, compressed gas in solution, asphyxiant gas and oxidizing gas. A non-flammable, nonpoisonous compressed gas (Division 2.2) means any material (or mixture) which:
In the study of combustion, the adiabatic flame temperature is the temperature reached by a flame under ideal conditions. It is an upper bound of the temperature that is reached in actual processes. There are two types of adiabatic flame temperature: constant volume and constant pressure, depending on how the process is completed.
GHS hazard statements Hazard statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). They are intended to form a set of standardized phrases about the hazards of chemical substances and mixtures that can be translated into different languages. [1] [2] As such, they serve the same purpose as the well-known R-phrases, which they are intended to ...
Hazard pictograms are one of the key elements for the labelling of containers under the GHS, along with: [2] an identification of the product; a signal word – either Danger or Warning – where necessary. hazard statements, indicating the nature and degree of the risks posed by the product. precautionary statements, indicating how the product ...
Description. Temperature-relative humidity chart - PMV method.pdf. English: This chart represents the acceptable combination of air temperature and humidity values, according to the PMV/PPD method in the ASHRAE 55-2010 Standard. The representation is made on a temperature-relative humidity, instead of a standard psychrometric chart.
