Approvals

Underwriter’s Laboratories is one of the world’s premier safety testing and certification sources. Many applications require UL approval for insurance and/or other compliance purposes. There are several areas of interest, but the most applicable is UL 508, the Standard for Industrial Control Equipment. For more information on UL, check their Web site at www.ul.com.

Madison Company offers many sensors with UL 508 approval via file E54633. Those product approvals are to a specific design. Some modifications to an approved design may cause the approval to be invalid. Should that be a critical issue for you, contact us to determine what course of action would be best.

Canadian Standards Association (CSA) tests products for compliance to national and international standards and issues certification marks for qualified products. Certification marks tell potential users that a product has been evaluated by a formal process involving examination, testing and follow-up inspection, and that it complies with applicable standards for safety and performance. CSA is recognized throughout Canada as the premier certification organization for electrical products. For more information on CSA, visit their Web site at www.csagroup.org.

As with UL approval, CSA certification is design-specific. Therefore, modifications to a certified design may cause the certification to be invalid. Please confer with Madison Company if this certification is crucial for your application.

The liquid level switch product is normally approved as a Class 2258 02 Process Control Equipment for hazardous locations classified as Class A, B, C and D; Class II, Groups E, F and G; Class III. For more information on CSA, visit their Web site at www.csagroup.org.

The 15 member nations of the European Union (EU) have created a set of product-specific regulations with which those companies doing business in those nations must comply. The EU’s "New Approach Directives" constitute its unified set of health and safety regulations, symbolized by the CE mark. The mark is required for a broad range of products, including machinery, medical devices and electrical/electronic products. Madison Company self-certifies many of its liquid level float switches to CE specifications EN60730-1 and EN60730-2, and Low Voltage Directive (72/73/EEC).  View the individual sensor or float switch product pages for specific approvals. 

NSF International sets standards for products and systems related to public health, safety and the environment with focus on the essential elements of water, food environment and air. The NSF Certification programs are accepted and frequently mandated by public health regulators throughout the United States, as well as internationally. Madison company offers over 30 NSF approved sensors which meet NSF/ANSI Standard 169 - Special Purpose Food Equipment and Devices.

Madison Company knows the obligations inherent to the REACH European regulation and will comply as required. Madison Company does not manufacture and/or import preparations or articles containing chemical substances according to REACH.

Madison's Standard level switches and sensors – under codes I0571136, High level sensor and I0571137, Low level sensor – do not contain SVHCs in concentrations greater than 0.1% by weight.

Other Madison products can be reviewed for compliance by requesting, by part number, such a REACH compliance review. Please contact us by phone at (203) 488-4477 or by email at info@madisonco.com.

Madison Company wants to assure our customers that all of our products comply with the RoHS and WEEE directives released by the European Union (E.U.).  We are also concerned with keeping our materials free of conflict minerals.  You may view our Conflict Mineral Report here for more information.

Beginning July 1, 2006, the Restriction of Hazardous Substances, or RoHS, directive (2011/65/EC) will restrict the level of use of four metals, Hg-Mercury, Pb-Lead, Cr(VI) - Hexavalent Chromium and Cd - Cadmium, in electronic products sold in Europe. Two flame-retardants, PBB - Polybrominated biphenyls and PBDE - Polybrominated diphenyl ethers, will also be restricted in their level of use in these products. The directive on Waste Electrical and Electronic Equipment, or WEEE, which took effect on August 13, 2005, requires all producers, distributors and importers of electrical and electronic equipment to finance "end of life" arrangements, such as collection and recycling, for their products.

Madison's products are considered exempt from the requirements of the RoHS directive, since they are currently listed under Category 9 (Monitoring and Control Equipment).

One of our goals is to produce products that have minimal impact on the environment; we are making every effort to ensure that the majority of our products do not exceed the hazardous substance limits outlined in the RoHS directive (2011/65/EC). You can also be sure that, should any modifications to the two directives apply to our products, we will make whatever modifications are necessary to maintain our compliance.

We would be happy to answer any questions you may have concerning a specific Madison product and its RoHS compliance. Please contact us by phone at (203) 488-4477 or by email at info@madisonco.com.
