BS 8494:2007 PDF

Scope: This British Standard specifies requirements for the construction, testing and performance of electronic portable and transportable apparatus for the detection and measurement of carbon dioxide (CO2) in indoor ambient air, which includes air entering mechanical ventilation systems in dwellings, commercial premises and industrial premises. This standard covers equipment to indicate up to typically 20 000 ppm (2%) CO2 in air. NOTE 1 The CO2 measuring capabilities of indoor air quality apparatus are covered by this standard. NOTE 2 The measurement capabilities of electronic portable and transportable apparatus that are additional to the measurement of CO2 are not covered in this standard. Other standards that cover these additional measurement capabilities include BS EN 50379 for electronic portable combustion gas analysers and BS EN 45544 for toxic gas detection apparatus having an alarm function for alerting an operator to an unsafe workplace atmosphere.
