This standard specifies the methods for the determination of phosphorus in non-alloyed steel and irons by the molybdenum blue spectrophotometric method.
ČSN EN is a set of standards created by the Czech Technical Standardization Institute (ČSN) in collaboration with the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO).
Like other standard norms, ČSN EN standards cover a wide range of industries and provide guidelines for ensuring quality, safety, and environmental protection. Adherence to ČSN EN standards can benefit organizations by improving their efficiency, reducing costs, increasing customer confidence, and enhancing their reputation.
Some examples of ČSN EN standards include those related to energy management systems, environmental management systems, and medical devices. These standards provide guidance for businesses and organizations to ensure that their products and services meet certain quality and safety requirements and are compatible with international standards.
