BS EN 14625 specifies a continuous measurement method for the determination of the concentrations of ozone present in ambient air based on the ultraviolet photometric measuring principle. This standard describes the performance characteristics and sets the relevant minimum criteria required to select an appropriate ultraviolet photometric analyzer by means of type approval tests.
BS EN 14625 also includes the evaluation of the suitability of an analyzer for use in a specific fixed site so as to meet the data quality requirements as specified in Annex I of Directive 2012/50/EC [1] and requirements during sampling, calibration and quality assurance for use.
The methods described in BS EN 14625 is applicable to the determination of the concentration of ozone present in ambient air up to 500 μg/m3. This concentration range represents the certification range for ozone for the type approval test.
NOTE 1 Other ranges may be used for measurement systems applied at rural locations monitoring ecosystems.
NOTE 2 When the standard is used for other purposes than Directive 2012/50/EC, the ranges and uncertainty requirements may not apply.
Who is BS EN 14625– Ambient air for?
BS EN 14625 on ambient air is relevant to:
- Manufacturers of air quality control devices such as diffusers
- Researchers and scientists
- Environmentalists
Why should you use BS EN 14625– Ambient air?
Analyzer is a measuring system that provides an output signal which is a function of the concentration, partial pressure, flow or temperature of one or more components of a gas mixture.
BS EN 14625 describes a measurement method that determines the concentration of ozone, extracts the sample, and analyzes it using ultraviolet photometry.
BS EN 14625 specifies standard requirements and test methods for the determination of the concentration of benzo[a]pyrene in ambient atmospheres.
BS EN 14625 describes the performance characteristics and sets the relevant minimum criteria required for determining the concentration of ozone.
In BS EN 14625, 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 14625 is a best practice guidance standard that provides complete requirements and test procedures for determining the concentration of ozone and controlling their quality, which will reduce pollution, increase efficiency, and ease health concerns.
