Why This is Different
UNIX certification and the UNIX brand is part of The Open Group internationally recognized portfolio of open systems certification programs which represent the three primary ingredients required for open systems:

Widely accepted and available specifications describing the software interfaces between components of a computer system such as the operating system, networks, and applications.
Computer systems developed to meet The Open Group specifications and marketed by vendors.
The assurance that products meet agreed specifications and conformance requirements by passing the rigorous tests developed by The Open Group

The UNIX trademark, also known as the brand has created an opportunity for more choice in the market for computer system buyers. It enables cost and time savings for suppliers and stimulates competition in a larger, unified market for UNIX system products clearly identified by the UNIX brand.

From February 1995, computer systems have carried the UNIX brand if:

They guarantee to support the services specified in the Single UNIX Specification.

Customers can identify UNIX certified products by the Open Brand logo and the mandatory attribution declaring to which version of the specification the product complies:

UNIX 93 applies to UNIX system products which pre-date the Single UNIX Specification.

UNIX 95 applies to UNIX system products which conform to the Single UNIX Specification.

UNIX 98 applies to UNIX system products which conform to the Single UNIX Specification , Version 2.

UNIX 03 applies to UNIX system products which conform to the Single UNIX Specification , Version 3.

UNIX V4 applies to UNIX system products which conform to the Single UNIX Specification , Version 4.

See the platform pages for the latest information.

In licensing the UNIX brand a vendor warrants and represents that every certified product:

Conforms to the specification.
Meets The Open Group's test and certification requirements.
Will continue to conform to the specification.
Will be rectified within an agreed time should it be found to be non-conformant.

UNIX certification is widely recognized as the international symbol of assurance in open systems. By the end of 2001, the value of procurements of open systems referencing the brand had exceeded $25 billion.

A Specification of Value

The Single UNIX Specification benefits the whole IT industry. For users, products that support the Single UNIX Specification provide a powerful open platform for the development, implementation and management of mission-critical computer systems. The specification will facilitate freedom of choice across the widest possible range of systems therefore protecting investment in existing software and data. 

For software vendows, the Single UNIX Specification offers an opportunity to cut significantly the cost of developing and maintaining their products. It also expands the market opportunity by expanding the market, cutting time-to-market and reducing product development costs.

For system vendors, the Single UNIX Specification unifies a previously fragmented market and offers the chance for all to compete on equal terms, while reducing the investment required to maintain technical incompatibilities.

From now on, system vendors have a standard specification and a branding program underpinning a widely recognized brand through which they can bring to market their UNIX system products.

Under the UNIX certification program, products that implement the services as specified in the Single UNIX Specification are able to carry the UNIX trade mark.

As a result, customers will be assured that, by asking for a UNIX certified system, they will derive the associated business benefits of the guarantee. The development and quality assurance of UNIX certified systems is aided by the availability of a suite of software testing tools. These have been developed to cover all aspects of the Single UNIX Specification: core system calls; commands and utilities; UNIX extensions; and networking interfaces.
