ASTM D7164 Nitrate and Nitrite Determination in Water by UV Absorption

ASTM D7164 Nitrate and Nitrite Determination in Water by UV Absorption: Eurolabs Laboratory Testing Service

ASTM D7164 is a widely recognized standard for the determination of nitrate and nitrite ions in water using ultraviolet absorption spectroscopy. This standard is developed and maintained by ASTM International, one of the leading standards development organizations globally.

The standard provides detailed procedures for sample preparation, instrument calibration, and data analysis to ensure accurate and reliable results. The scope of the standard includes water samples from various sources, including drinking water, wastewater, and industrial effluents.

Standard Development Organizations (SDOs) and Their Role

ASTM International is one of the many SDOs that develop standards for various industries and sectors. Other notable SDOs include ISO (International Organization for Standardization), EN (European Committee for Electrotechnical Standardization), TSE (Turkish Standards Institution), and others.

The role of SDOs is to provide a platform for experts from various fields to collaborate, discuss, and agree on the requirements and specifications for specific products, services, or processes. These standards are developed through a consensus-based process, ensuring that they meet the needs of all stakeholders involved.

Legal and Regulatory Framework

ASTM D7164 is widely adopted by regulatory bodies around the world as a reference standard for nitrate and nitrite determination in water. The standard is also recognized by various industries and sectors, including drinking water treatment plants, wastewater treatment facilities, and industrial processes.

In the European Union, for example, the standard is referenced in the Drinking Water Directive (98/83/EC) and the Urban Wastewater Treatment Directive (91/271/EEC). Similarly, in the United States, the standard is recognized by the Environmental Protection Agency (EPA) under the Safe Drinking Water Act (SDWA).

ASTM D7164 is a critical test for ensuring the quality of water supplies. Nitrate and nitrite ions can have adverse effects on human health, particularly in infants and pregnant women.
