Winters Approvals / Certifying Agencies

3A

The objective of the 3A Sanitary Standards Committee is to formulate standards and accepted practices for equipment and systems used to process milk and milk products. Such standards are developed through all levels of sanitarians, equipment manufacturers and equipment users so those standards are acceptable to those involved in the sanitary aspects of dairy and related industries. The 3A Symbol Administrative Council authorizes manufacturers to display the 3A symbol on processing equipment that is in compliance with 3A Sanitary Standards.

CSA

The Canadian Standards Association (CSA) includes Canadian consumers, manufacturers, labour, government, and other regulatory agencies among its actively participating influences. The various groups work together to generate standard requirements (CSA standards) that demonstrate product quality, enhance market acceptability and improve quality and safety control procedures in manufacturing and construction for the Canadian marketplace. The standards generated by CSA are the cornerstones for determining a product’s eligibility for certification in hazardous locations in Canada. CSA also performs product evaluation, testing and ongoing inspection to these standards and also to American and European standards through new inter-laboratory agreements.

CE

Having a CE marking is a declaration that Winters’ product conforms to a specific Directive adopted by the EEA (European Economic Area), and is a requirement if the product is to be sold into any of the countries in this 18 member group. CE is an abbreviation for the “Conformité Européenne”, meaning European Conformance. Unlike dangerous location approvals, CE markings are granted to products that conform to Directives which were developed using IEC and Cenelec standards. The Directives that affect transmitters are the EMC (Electromagnetic Compatibility) and LVD (Low Voltage) Directives. These state that the products must meet specific electromagnetic emission and immunity, as well as electrostatic discharge standards.

RoHS

The Restriction of Hazardous Substances Directive restricts the use of six hazardous materials in the manufacturing of electronic and electrical equipment.  These materials are: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ether. Bring “RoHS compliant” is commonly interpreted as bring “lead-free”, or having under 0.1% of lead in the material.

ISO 9001:2008

Winters is a ISO 9001:2008 Corporation. ISO 9001:2008 requires an organization to demonstrate its ability to consistently provide products that meet customer and regulatory requirements, and enhance customer satisfaction through effective application of the system, including processes for continual improvement of the system and the assurance of conformity.

UL/ULC

Underwriters Laboratories and Underwriters Laboratories of Canada maintain a high commitment to public safety and dedication to exceed customer expectations through continual improvement in the delivery of quality services. The organizations develop and publish standards, classifications and specifications for products having a bearing on fire, accident or property hazards. If a product carries the UL mark, it means that UL found the product meeting UL’s safety requirements. These requirements are based primarily on UL’s own published Standards for Safety.

NACE

The National Association of Corrosion Engineers recommends practices such as methods of selection, design, installation, maintenance or operation of material or systems where corrosion is a factor. Some recommended practices focus on details of construction of a corrosion control system, methods of treating the surface of materials to reduce corrosion, requirements for using devices to reduce corrosion, and procedures for increasing the effectiveness, safety and economic benefits of an installation or system.

SIL 2

SIL, or Safety Integrity Level, defines the risk-reduction level or performance in a function. In general, there are four levels of SIL: 4 being the most dependable and 1 providing the least risk protection. SIL levels are determined based on quantitative as well as qualitative factors.

Ingress Protection (IP) Ratings

The IP Code indicates the degree of protection provided by enclosures for electrical equipment (i.e. IP65 = No dust entry and protected against low pressure jet of water).

The first numeral indicates protection of persons against access to dangerous parts and protection of internal equipment against the ingress of solid foreign objects.

X - Protection unspecified (untested)

0 - No special protection provided

1 - Protection of hand against accidental access to dangerous parts, and protection of equipment against objects larger than 50mm

2 - Protection of fingers against access to dangerous parts, and protection of equipment against objects larger than 12mm

3 - Protection against objects larger than 2.5mm (e.g. tools, wires)

4 - Protection against objects larger than 1mm (e.g. line tools, wires)

5 - Protection against entry of dust in sufficient quantity to interfere with satisfactory operation of equipment

6 - Complete protection against entry of dust

The second numeral indicates protection of internal equipment against harmful ingress of water.

X - Protection unspecified (untested)

0 - No special protection provided

1 - Protection against drops of water falling vertically

2 - Protection against drops of water falling vertically when the object is tilted by up to 15 degrees from its normal position (in any direction)

3 - Protection against spraying water at up to 60 degrees from the vertical

4 - Protection against splashing and spraying water from all practicable directions

5 - Protection against a low pressure jet of water from all practicable directions

6 - Protection against heavy seas or a strong jet of water from all practicable directions

6D - Protection against driving rain at angles down to horizontal

7 - Protection against immersion

8 - Protection against submersion (tests subject to agreement, but no less severe than numeral 7).

Hazardous Location Definitions

Class I - Locations in which flammable gases or vapours are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.

Class II - Locations which are hazardous because of the presence of combustible dust.

Class III - Locations which are hazardous because of the presence of easily ignitable fibers or flyings, but in which such fibers or flyings are not likely to be suspended in air in quantities sufficient to produce ignitable mixtures.

Division 1 - Locations in which hazardous concentrations in the air exist continuously, intermittently, or periodically under normal operating conditions.

Division 2 - Locations in which hazardous materials are handled, processed, or used, but where such materials are normally within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown.

Group A - Atmospheres containing acetylene.

Group B - Atmospheres containing hydrogen, or gases or vapours of equivalent hazard, such as manufactured gas.

Group C - Atmospheres containing ethyl-ether vapours, ethylene, or cyclo-propane.

Group D - Atmospheres containing gasoline, hexane, naphtha, benzine, butane, propane, alcohol, benzol, lacquer solvent vapours, or natural gas.

Group E - Atmospheres containing metal dust, including aluminum, magnesium and their commercial alloys and other metals of similar hazardous characteristics.

Group F - Atmospheres containing carbon black, coal or coke dust.

Group G - Atmospheres containing fl our, starch or grain dust.

Hazardous Location Definitions - International

The International Electrotechnical Commission (IEC) classifies hazardous locations by Zone and Group. Zone is similar to the term “Division” in that it defines the likelihood of hazard:

Zone 0 - An area in which an explosive gas/air mixture is constantly present or present for long periods of time.

Zone 1 - An area in which an explosive gas/air mixture is likely to occur during normal operation (Similar to Division 1).

Zone 2 - An area in which an explosive/air mixture is not likely to occur but if so, only for short periods of time (Similar to Division 2).

NEMA Enclosure Ratings

Certain Winters products (i.e. pressure transmitters and pressure switches) can be classified per the National Electrical Manufacturer’s Association Enclosure (NEMA) classifications. NEMA is a non-profit trade organization composed of manufacturers of electrical power apparatus. NEMA created voluntary standards for electrical enclosures. These classifications describe the environment in which the product can be used due to the protection the enclosure provides. (“Enclosure” includes electrical and mechanical connections and external adjustments). Among others, NEMA classifies enclosures based on the effects of external icing, corrosion and rusting, or contamination from oil and coolants.

Pressure switches, transmitters and other electronic products may also be classified according to the voluntary standards set by NEMA for electrical enclosures.

CRN (Canadian Registration Number)

The Canadian Registration Number (CRN) is a number issued by each province/territory in Canada to the design of boilers, pressure vessels or fittings. Industrial instrumentation such as pressure gauges, thermometers and related accessories all fall under this jurisdiction. The CRN identifies that the design has been accepted and registered for use in that province/territory. Please refer to the individual product pages to see if a series is CRN registered.
