Not only do food blenders need to be safe in terms of function, they also need to be tested to ensure that the materials used inside are food-safe.  Some of the standards that we take under consideration when developing testing protocols and inspection procedures for blenders include:
 
NSF/ ANSI Standards
 
NSF/ ANSI ensure the following standards are used during the production stage of the blender:
 

• NSF/ANSI Standard 2:
• NSF/ANSI Standard 8:
• NSF/ANSI Standard 169:

International Electrotechnical Commission
The IEC 60335-1 standard is used for safety inspections of electrical blenders for household purposes. The rated voltage of a blender cannot exceed more than 250 volts.
 

CE Marking

CE marking is required to be visible on household product that will be circulated throughout Europe

 
Underwriters Laboratories

• The Underwriters Laboratories or UL standard 197 is used for commercial electric blenders rated at 600 volts or less.
• The Underwriters Laboratories Standard 763 is used for commercial motor-operated blenders

American Standards for Testing and Materials

• The American Standards for Testing and Materials or ASTM F1568-08 Standard Blender Specification is used for commercial food blenders.
• The ASTM F952-08 Standard Specification for Electric Blenders covers commercial food blenders that contains a manual-feed.
