What is BS EN 1747-11– Methods for Measurement of air pollution about?
BS EN 1747-11 specifies a method for measuring the black smoke index of an ambient air sample. The method is based on the staining effect of particles which is produced when a sample of air is drawn through a filter paper.
The method described in BS EN 1747-11 is intended for the measurement of a black smoke index in the range 6 to 375 in the ambient atmosphere. It is based on the measurement of reflectance. The method does not measure the mass concentration of particles Directly.
Who is BS EN 1747-11– Methods for Measurement of air pollution for?
BS EN 1747-11 on measurement of air pollution is relevant to:
- Manufacturers of air quality controlling devices such as diffusers
- Researchers and scientists
- Environmentalists
Why should you use BS EN 1747-11– Methods for Measurement of air pollution?
Black smoke is the strongly light-absorbing, particulate material suspended in the ambient atmosphere.
BS EN 1747-11 specifies requirements and test methods for the determination black smoke index in ambient air atmospheres.
BS EN 1747-11 describes the performance characteristics and sets the relevant minimum criteria required for determining the black smoke index in gases and vapour.
In BS EN 1747-11, performance criteria and test procedures for measuring air quality are provided to test and manufacture air quality measuring diffusers. This helps create an improved solution to deal with harmful gasses emitted by stationary sources, which are very toxic.
As a whole, BS EN 1747-11 is a best practice guidance standard that provides complete requirements and test procedures for determining the black smoke index of vapor and gases using a diffuser and controlling their quality, which will reduce pollution, increase efficiency, and ease health concerns.
