It may also be called a certificate of conformance or certificate of conformity.. Although conformance testing may include some of these kinds of tests, it has one fundamental difference -- the requirements or criteria for conformance must be specified in the standard or specification. At the end of the 1-year period, the implementer would have to correct the errors to renew the certificate. Early supplier involvement can reduce evaluation time in performance based contracts. sizable latitude in how to accomplish the end purpose. Brand-name-or-equal specifications have a These will be cheaper, more reliable and easier to source.

Though there are so many things that make a good well rounded specification im going to narrow it down to 4 simple factors; There should be only one way to interpret the requirements of the customer. Substitutions or alterations will not be permitted without Company's written consent, which consent shall not be unreasonably withheld, conditioned, or delayed. 5. competition consistent with seeking overall economy for the As a procurement professional . Finally, the testing policy and procedure should identify and define the actions of the organization(s) responsible for conducting the tests, handling disputes, and issuing certificates (or brands) of validation. By definition, a Some standards have no official testing organizations. It is also possible that implementations may not be able to implement all the features. this would be prohibitive. Development of the test suite may well be the costliest part of the conformance program. In contrast to the design approach, With any standard or specification, eventually the discussion turns to "how will we know if an implementation or application conforms to our standard or specification?" the methods for establishing and maintaining a QPL varies widely Several of the W3C Working Groups have developed conformance test suites or tools e.g., SVG, CSS, and HTML.

The buyer uses the results of the testing to verify that a seller provides a product that conforms to the specification and meet procurement requirements. Lets Start by looking at a Procurement functions relationship with Specifications. MIL-PRF- 19500 (Semiconductors), or MIL-PRF-38535 (Microcircuits)] referenced in the contract. /Length 10 0 R Tip - Never design and make a product if there is an 'off-the-shelf' part available. Generically, a conformance test suite is a collection of combinations of legal and illegal inputs to the implementation being tested, together with a corresponding collection of "expected results." The procedures should also contain information on what must be done operationally when failures occur. It is generally inspected during customs clearance if the product being imported requires it. While actual testing (1st or 3rd party testing) and certification (branding) can be carried out by various organizations, it is essential that there be a centralized sponsor or owner of the conformance testing program. The test software, consisting of a set of test files (i.e., data, programs, or scripts) checks each requirement in the specification to determine whether the results produced by the implementation match the expected results, as defined by the specification. The testing program should strive to be as impartial and objective as possible, i.e., to remove subjectivity of both the procedures and the testing tools. ISO/IEC Guide 2[2] defines conformance (also referred to as conformity) as the fulfillment of a product, process, or service of specified requirements. broad groupings are more particular types, including: brand-name The test suites are available athttp://xw2k.nist.gov/xml/index.html. a. Some standards have subsequent documentation for the test methodology and assertions to be tested. ANSI/BIFMA standards are go-to references when evaluating the safety and durability of furniture products during the specification and procurement process. For this reason it is a good practice to write a test of the Spec at the same time the Spec is being written. Conformance testing provides software developers and users assurance and confidence that the conforming product behaves as expected, performs functions in a known manner, or possesses a prescribed interface or format. Interoperability is defined as the capability of two or more systems to exchange and use information. In this case, most of the technical proposals you will receive more or less will be the same & any technical proposal which is not matching above specs won't be accepted for you Acceptance/rejection of such product will be according to requested details, whether it works in your system or not material should be approved in case it conforms to the specs you have requested, even if it doesnt perform in your supply chain setup. https://www.nist.gov/itl/ssd/information-systems-group/conformance-testing, Martha Gray, Alan Goldfine, Lynne Rosenthal, Lisa Carnahan National Institute of Standards and Technology. specifications; performance specifications; and the Qualified However, these methodologies all follow the same basic strategy - falsification testing; and the same basic process - analyze the specification for test assertions or test requirements, write a test purpose for each test, and create and document a test case which realizes each test purpose.
