Certification

EMC Certification and CE marking have been required by the European Commission since January 1st, 1996 in order for electrical and electronic products to be sold in the European Economic Community. Because industrial environments are often hazardous, different to the standard specification EN55032/24 for commercial data transmission use, EN61000-6-4/2 is specially set.

Heavy Industrial CE EN61000-6-4, EN61000-6-2
EMC Certification and CE marking have been required by the European Commission since January 1st, 1996 in order for electrical and electronic products to be sold in the European Economic Community. Because industrial environments are often hazardous, different to the standard specification EN55032/24 for commercial data transmission use, EN61000-6-4/2 is specially set for hazardous industrial application use to avoid EMI-induced malfunction. Therefore, industrial EMC plays a crucial role in industrial environments. Leonton's industrial products all have EMC Certification EN61000-6-4/2 to ensure they work reliably in hazardous environments.

It offers a series of inspection, advisory, education and training, testing, auditing and analytics services for ensuring that products meet safety standards based on probable hazards associated with the product. UL’s reputation for integrity and confidence in safety and its UL mark, as the most recognized and trusted symbol of safety, both reflect great credits in its profession. In the field of industrial safety, UL 508, UL 61010 and ANSI/ISA 12.12.01 are the standards specifically required for various industrial applications and applied to industrial network devices. These standards ensure that the devices will not be the cause of danger under normal operating conditions and even in explosive environments. Through vigorous and complex testing processes, Leonton’s industrial Ethernet switches are not just compliant with UL safety requirements, but also UL-certified Nonincendive Electrical Equipment for Use in Class I Division 2 to carry the UL Listed mark.

Corrosion Protection

Corrosion Protection
Corrosion Protection
In the environments that contain corrosive substances, it is necessary to give electronic devices adequate protection to prolong the products' lifespan. Take corrosion protection for instance, if the field equipments are not corrosion proof, they will be vulnerable to the harsh environmental conditions, accelerating the depreciation of the devices. In order to improve the tolerance of electronic devices and even prevent them from corrosion, Leonton Technologies offers Corrosion Protection Product Series made by and from unique and rigorous process, selected materials, and product testing, including IEC60068-2-60 gas corrosion test, IEC60068-2-11 salt spray test and IEC60068-2-52 salt spray cyclic test, to protect the PCB and its components in the units from corrosion-causing conditions, such as moisture, salt spray, chemicals, dust, corrosive gases, and biological influences, to provide and ensure the anti-corrosion capability of the units. Therefore, Leonton provides its Corrosion Protection Product Series to reduce end-users’ replacement costs by greatly alleviating the deterioration that is caused by harshly corrosive environments.

EN50155

EN50155
EN50155
EN50155 is the verification criteria for the low-voltage electronics installed on railway vehicles. This standard provides system integrators the lists of EN50155-certified electronics that are suitable for railroad environment uses and have passed the complete specification test required by the railway industry. The complete specification test for EN50155 includes tests for extreme operating temperatures, shock, vibration and EMC/EMI/EMS, which verifies that in any railway vehicle the equipments can operate stably and do not interfere with the operation of other equipments. Trains usually face the challenge of unstable voltage caused by the frequent vibration and are involved with passengers’ safety. Therefore, the systems operating on them must be designed to prevent natural and man-made interference. That is why all the electronic equipments for railway use must be able to adapt to the various levels of altitude, humidity, shock, vibration, temperature and electric properties to provide utmost performance and satisfy the requirements of railway traffic safety.

EN50121-4

EN50121-4
EN50121-4
EN50121-4 is the verification criteria specifically for equipment used near railways. Due to the many Control Communications Systems and traffic control signals around the railway, EMC is crucial for avoiding traffic accidents caused by Electromagnetic Interference. Therefore, all equipment installed around the railway must be certified by EN50121-4 before being used in the application.

E-Mark

E-Mark
E-Mark
E-Mark is widely recognized in the automobile industry, covering the safety requirements of automobile vehicles and vehicle-mounted ESAs (electronic subassemblies) to be in compliance with Economic Commission of Europe (ECE) Regulation and European Union (EU) Directives across Europe. All vehicles and components entering the EU market should obtain E-Mark certification issued by the Transportation Department of each country. In addition, the value of an E-mark can extend beyond Europe, since many countries model their own compliance requirements to those of the European Union and accept E-Mark reports as suitable proof of compliance.

NEMA TS2

NEMA TS2
NEMA TS2
NEMA TS2 is a standard for traffic control assemblies, such as traffic lights, emergency road condition signs and walk/don't walk signs. The standard is designed for manufacturers to meet or exceed a set of minimum requirements, and it is also recognized as a guarantee of safe and reliable operation. To ensure high network reliability in your Intelligent Transportation System (ITS), Leonton offers both Ethernet switch and media converter that are compliant with NEMA TS2.

DNV

DNV
DNV
DNV(Det Norske Veritas), a Norwegian Classification society pioneer, set the standard for all the equipments used in marine applications. As long as equipments are to be used in these environments, they must comply to the DNV certification to ensure the safety of the crew and other onboard systems. To enhance navigation safety, maritime nations around the world established their national institutes of marine surveying to perform statutory inspections and strict ship inspections to ensure they satisfy the requirements of the shipping, insurance and shipbuilding industry. In marine applications, marine-specific safety regulations such as DNV are essential to the industry due to the unique environments such as frequent vibration, shock, shaking, EMI, radiation interference, high humidity, high temperature, saline matter and other hazards.

ISA 12.12.01

ISA 12.12.01
ISA 12.12.01
ISA 12.12.01 is an American standard for all equipment intended for use in Hazardous Locations. The purpose of this standard is to provide minimum requirements for the design, construction, and marking of electrical equipment or parts of such equipment for use in hazardous locations which are classified into Class and Division. The equipment, in normal operation, is not capable of causing ignition of the surrounding atmosphere under the conditions prescribed in this standard, although the equipment may contain electronic components that operate at incendive levels and may also have field wiring that is incendive. Requirements for Class I, Division 2(C1D2) equipment is to ensure that under normal operating conditions equipment is not capable of igniting the specified flammable gas or vapor-in-air mixture.

ATEX

ATEX
ATEX
ATEX directives classify areas where hazardous explosive atmospheres may occur in zones. The classification given to a particular zone, plus its size and location, depends on the likelihood of an explosive atmosphere occurring and its persistence if it does. All organizations in the European Union must follow ATEX directives. It applies minimum Essential Health and Safety Requirements (EHSRs) to help protect employees from explosion risks in areas with an explosive atmosphere.

IECEx

IECEx
IECEx
The IECEx System is an international IEC system for Certification to Standards relating to the safety of equipment installed in a potentially explosive atmosphere. These hazardous areas include places where flammable liquids, vapours, gases or combustible dusts could present a fire or explosion hazard. IECEx covers products, personnel competencies and services such as equipment design, selection, installation, inspection, maintenance, repair, overhaul, and reclamation. IECEx certification can therefore involve a whole enterprise, so IECEx can be said to be a standard that combines product design and industrial safety, which is why the EU enforces it strongly.
