You may also look to gain insight into companies by searching current patent information to learn which companies in the industry are filing for patents and releasing new ideas.

Depending on your research need, you can look for patents and patent information by narrowing your search using the following criteria:

Information about Technical Standards

Standards are a vital industry component because they enhance safety and improve the quality of consumer and industrial products. You can research which standards are prominent in the ice cream industry and which determine safety and other regulations. Knowing standard specifications for certain equipment in the ice cream industry is also critical information for franchisees and entrepreneurs. 

The IHS Market Standards Store External will provide the most recent identifying number, title, description, and abstract for any given standard. You can search for standards by keyword, publisher, or industry. Publishers include (but are not limited to) ASTM International Standards and UL Standards, as well as military and foreign standard publishers. Once you determine which standard you are looking for, you can contact the Library of Congress Technical Reports Division to determine if we have the standard you need.

The ASTM International Standards are available in the Science, Technology, and Business collection, with the most recent standards located in our self-serve reference collection.
