– Improper Power Input
– Applications Outside of Product Labeling
– Specific Conditions and Environments that could result in
product failure or Hazards and Unsafe events
– User Limitations such as Age and other Demographics
– Improper Disposal
Products Must Be Accompanied By Sufficient Clear Instructions, Warnings and Labels to
mitigate the possibility to a reasonable level for unsafe occurances
318-595 Safety
Test Labs
• Test Products to key Safety Standards and authorize a product
to be marked with test lab label as well as key standard label
• Labs may need to be certified as part of standards process
• Some Test Labs also propose and harmonize Safety
Standards (UL, CSA, etc)
• Labs Often have their own label or marking that a product
shall bear to indicate passing this test labs regime

• Design Inputs
• Requirements, Constraints and other information which is needed to
formulate a set of design outputs for a given product.
• Design Inputs must include customer (user) level requirements as well
as product level and flow down to block level requirements
• Design Outputs
• All drawings, documents, procedures, instructions and other
information necessary to describe the constituent parts, assembly,
manufacturing process, service and disposal processes for a product.
• Design outputs from one team may sometimes become the design
inputs to another team.
318-595 Safety
Design Control Terms
• Verification
• Design analysis, simulation or prototype testing which provides
objective evidence that a design meets all of its block or product level
requirements
• Is performed at sub-block, block and system levels and usually requires
lab testing

CPSC Overview:
Sanctioned by the US Congress (No direct cabinet level tie)
The U.S. Consumer Product Safety Commission is charged with protecting the public from unreasonable
risks of serious injury or death from more than 15,000 types of consumer products under the agency's
jurisdiction. Deaths, injuries and property damage from consumer product incidents cost the nation more than
$700 billion annually. The CPSC is committed to protecting consumers and families from products that pose
a fire, electrical, chemical, or mechanical hazard or can injure children. The CPSC's work to ensure the safety
of consumer products - such as toys, cribs, power tools, cigarette lighters, and household chemicals contributed significantly to the 30 percent decline in the rate of deaths and injuries associated with consumer
products over the past 30 years.

What is the “CE” Mark?
CE Marking is the symbol “CE” as shown on the top of this page. The letters "CE" are the abbreviation of French
phrase "Conformité Européene" which means "European Conformity". The term initially used was "EC Mark" and
it was officially replaced by "CE Marking" in the Directive 93/68/EEC in 1993. "CE Marking" is now used in all EU
official documents.
CE Marking on a product is a manufacturer's declaration that the product complies with the essential
requirements of the relevant European health, safety and environmental protection legislations, in practice by
many of the so-called Product Directives
• “Essential Requirements" are the performance levels contained in harmonized standards
to which the products must conform.
• “Product Directives” are the legal directives and laws which specify the harmonized
standards for certain types and classes of products to conform. Ex; 95/94/EEC: Automotive
Products
• “Harmonized Standards” are the technical specifications (European Standards or
Harmonization Documents) which are established by several European standards agencies
(CEN, CENELEC, etc).
• CEN is the European Committee for Standardization.
• CENELEC is the European Committee for Electrotechnical Standardization.
318-595 Safety
Purpose of the CE Mark
• The CE Mark is a Manufacturer’s Declaration that the product placed onto the
EU market conforms with all the applicable essential requirements in the
harmonized standards. ie; The Product is Safe and Complies with all
Standards
• CE Marking on a product indicates to governmental officials that the product
may be legally placed on the market in their country.
• CE Marking on a product ensures the free movement of the product within
the EFTA & European Union (EU) single market (total 37 countries).
• CE Marking on a product permits the withdrawal of any non-conforming
products by customs and other enforcement authorities.
318-595 Safety
• CE Mark History
CE Mark
– 15 countries in original EU (European Union) established
harmonized standards
– EC/EEC (European Committee/European Economic
Community) is the body driving establishment of standards for
any product sold in or entering into the EU.
– Members may add additional more stringent standards but may
not contradict existing EC approved standards

www.iso.org
• ISO is a network of the national standards institutes of
148 countries, on the basis of one member per country.
• Central Secretariat in Geneva, Switzerland, coordinates
the system
• ISO is a non-governmental organization
• ISO occupies a special position between the public and
private sectors
• Many of its member institutes are part of the
governmental structure of their countries, or are mandated
by their government.
• Other members have their roots uniquely in the private
sector, having been set up by national partnerships of
industry associations.

• The ISO 9000 and ISO 14000 families are among ISO's most widely
known standards ever.
• ISO 9000 and ISO 14000 standards are implemented by some
610,000 organizations (companies & corporations) in 160 countries.
• The ISO 9000 family is primarily concerned with "quality
management“
• This means what the organization does to fulfill:
- the customer's quality requirements, and
- applicable regulatory requirements, while aiming to
- enhance customer satisfaction, and
- achieve continual improvement of its performance in pursuit of these
objectives.
