Approved material list

Approved Material List (AML) A list of approved suppliers and materials. Some companies seek to expand the AML to increase options for product design and to avoid single-source or end-of-hfe componenets. 

Pressure vessels and appurtenances should be constructed of stainless steel or other corrosion-resistant materials. Ideally, these steam generators should receive hot demineralized FW to minimize chemical treatment requirements. Alternatively, where a main boiler plant is installed, 100% steam condensate provides a good source of FW. In practice, it is very difficult to accurately control the correct amount of chemical feed. Chemicals are typically restricted to potable grade, deposit control agents such as polyacrylates, and other materials listed under the Code of Federal Regulations, CFR 21 173.310, or National Sanitary Foundation (NSF International) approval system. These boilers may be electrically heated or gas-fired. 

Note This table lists corresponding (not necessarily equivalent) International Materials which may be acceptable with the purchaser s approval. These materials represent family/type and grade only. Final condition or hardness level (where appropriate) is not specified. Materials listed for pressure applications may be utilized for non-pressure applications. All wear part material combinations must be selected in accordance with the requirements of 2.6A.2. 

In the context of fire protection system design, approved or listed equipment for fire service is generally understood to mean acceptable to the authority having jurisdiction (AHJ). The AHJ includes organizations or individuals that are responsible for accepting equipment, materials, an installation, or a procedure. In other words, the AHJ could be a fire marshal, insurance company, owner, or some other organization.

For use in the United States, the blue book memorandum includes an FDA-modified matrix designating the type of testing required for various medical devices and also a flowchart entitled BiocompatibiT ity Flow Chart for the Selection of Toxicity Tests for 510(k)s . The matrix also consists of two tables Table 1 - Initial Evaluation Tests for Consideration and Table 2 - Supplementary Evaluation Tests for Consideration. In general, the agency does not have a list of approved materials. 

If a material is not listed in the pharmacopoeia then reference must be made to a further Directive dealing with plastic materials in contact with food. Materials authorised for use in contact with food are generally acceptable for contact with pharmaceuticals (Table 3.12), but if this approach is taken it will also be necessary to provide a list of countries where the plastic has been approved for pharmaceuticals. If these two aspects can be covered, then toxicology data should not be required in the application. The Plastic Material in Contact with Food Directive lists, in an annexe, the monomers and starting materials which can be used for food purposes after January 1997. A second annexe lists the monomers which can be used, but which may be deleted if data were not supplied to enable the Scientific Committee to evaluate the product before 1 January 1996 (since then amendments have been inserted updating Annexe 1 as the data have been provided). Finally, specific migration limits are given for each material listed. 

Materials are regularly reviewed and approved. In September 2002, the NOSB approved 32 materials which, along with previously approved materials, will be published in the Federal Register as allowed under the NOP. If USDA does not publish the Federal Register notice before a certain date, certifying agents can assume all NOSB approved materials have been approved. To date, the Secretary has never used her power to delete materials from the Proposed National List approved by the NOSB. 

This activity includes information on contractual arrangements with suppliers and points of contact, relationship history (orders, fulfillments, disputes, resolutions), business evaluations, and technical evaluations of products and capabilities, including certifications for specific materials. For specific materials (or product families), there are approved supplier lists that identity supphers from whom the organization may order that material, often with preference ranking or ranking criteria.

Reliability data are available for many adhesives used in space environments for different orbits, different radiation, and different thermal-vacuum conditions. These data are available from approved materials and processes lists from NASA or from contractors for programs such as the Space Shuttle, Space Station, GPS, Hubbel telescope, and numerous satellite systems, some of which have been in orbit for over ten years. Adhesives used in military electronics have also been proven highly reliable in fighter planes, navy ships, ground and air communication systems, and navigation systems.

Hazardous material gate keeping T)ewe o and maintain an Approved Products List (APL), which documents materials authorized for the site and provides a web-based electronic chemical authorization request form that can be automatically routed to the proper approvers. 

If the application is such that the rubber will contact food or potable water a stabilizer that is on the list of FDA approved materials such as BHT must be used, so the supplier should be contacted to obtain their recommendation, depending upon the... 

A common practice in material specifications is to provide a list of one or more approved material suppliers. This is usually done in conjunction with the supplier product code for the material that has been specified. There are many reasons for doing this. It provides a confirmation that the material you specified will be used, exactly as you specified. This supplier may have a reputation for quality, reliability, and global availability. It also provides the foundation for a long-term business relationship. You are rewarding the resin supplier for the technical support they provided... 

Flavor. Dentifrices are used to refresh the oral cavity. Flavor oils and other flavoring materials are key to that function (see Flavors and spices). Generally recognized as safe (GRAS) flavors or flavors from approved lists are used. The most popular flavors are peppermint [8006-90-4], spearmint [8008-79-5], cinnamon [8006-79-9], and mixtures of these. Menthol is a principal constituent of the mint flavors and a source of refreshment and coolness. 

The ASME Code is written by a large committee and many subcommittees, composed of engineers appointed by the ASME. The Code Committee meets regularly to review the code and consider requests for its revision, inter pretation, or extension. Interpretation and extension are accomplished through code cases. The decisions are piibhshed in Mechanical Engineering. Code cases are also mailed to those who subscribe to the service. A typical code case might be the approval of the use of a metal which is not presently on the list of approved code materials. Inquiries relative to code cases should be addressed to the secretary of the ASME Boiler and Pressure Vessel Committee, American Society of Mechanical Engineers, New York. 

Colorants do not contribute to therapeutic activity, nor do they improve product bioavailability or stability. Indeed, they increase the cost and complication of the manufacturing process. Their main role is to facilitate identification and to enhance the esthetic appearance of the product. In common with all material to be ingested by humans, solid dosage forms are severely restricted in the coloring agents that are allowable. This situation is complicated by the lack in international agreement on an approved list of colorants suitable for ingestion.
