What is BS EN 203-2-9-2005 ?

Title: Understanding EN 50634-2010: The New Technical Standard for Terrestrial Digital Broadcasting

fire safety regulations have come a long way since the inception of BS476-22 in the 1980s. Over the years, advancements in materials, technology, and testing methods have necessitated updates to existing standards. The primary goal has always been to enhance life safety by preventing the uncontrolled spread of fire and smoke in buildings. Today, many countries have adopted updated standards, such as EN 1634-1, which provides a unified approach to fire resistance testing across Europe. These newer standards often take into account the latest scientific knowledge and technological advancements, offering a more comprehensive framework for evaluating the performance of door and shutter assemblies.

While BS476-22 may be considered outdated in some aspects, it still holds value in certain contexts. For instance, in regions where it is mandated by local building codes or specified in contractual agreements, compliance with BS476-22 is necessary. Additionally, some manufacturers may choose to test their products against this standard to cater to specific markets or maintain compatibility with existing installations.

However, architects, specifiers, and regulatory bodies are increasingly turning towards newer standards that offer a more comprehensive and internationally recognized approach to fire resistance testing. These updated standards provide a broader scope, including the evaluation of factors like heat insulation, integrity, and radiation.

EN 50634-2010: The New Technical Standard for Terrestrial Digital Broadcasting

EN 50634-2010 is a technical standard that regulates the production and performance of digital broadcasting equipment in Europe. Specifically, it focuses on the requirements for receivers used in terrestrial digital broadcasting, also known as DVB-T2.

The main purpose of EN 50634-2010 is to ensure interoperability and compatibility among different manufacturers' devices. This means that users can have confidence that their DVB-T2 receivers will work seamlessly with any television or audio system. It also guarantees that broadcasters can rely on uniform broadcast quality across various devices.

Key Requirements of EN 50634-2010

EN 50634-2010 has several key requirements that manufacturers must meet to ensure compliance with the standard. These requirements include:

Compliance with the essential safety requirements outlined in EN 62476-1-1.

The receiver should be capable of operating in the presence of both audio and video signals.

The receiver should have a maximum allowable output power of 100 dBm.

The receiver should have a maximum allowable input power of 100 mW.

The receiver should have a maximum allowable output current of 50 mA.

The receiver should have a maximum allowable input current of 50 mA.

The receiver should have a maximum allowable output voltage of 3.3 V.

The receiver should have a maximum allowable input voltage of 5 V.

The receiver should have a maximum allowable output current of 50 mA.

Conclusion:

EN 50634-2010 is a technical standard designed to ensure the interoperability and compatibility of digital broadcasting equipment in Europe. It is important for manufacturers to meet the key requirements outlined in the standard to ensure compliance and ensure that their products are qualified for the relevant markets.
