Ancillary materials

Effective specification control often can be estabUshed other than through requirements placed on the end use material, ie, the specification may beat on the taw materials, the process used to produce the material, or ancillary materials used in its processing. Related but supplementary techniques ate approved vendor Hsts, accredited testing laboratories, and pteptoduction acceptance tests. 

Undesired reactions catalyzed by materials of construction or by ancillary materials such as pipe dope and lubricants Boiling liquid, expanding vapor explosions (BLEVEs)... 

Materials of construction include ancillary materials like pipe dope. Utilities include ambient air. 

A paint rarely consists solely of pigment dispersed in a solution of a binder. For one reason or another, small quantities of ancillary materials called additives are included. The oldest and still the most important are the driers which are used in all air-drying and many stoving paints containing drying oils. They are organic salts of certain metals, notably cobalt, calcium, barium, zirconium and manganese, with lead very much in decline.

The major features of the [4 + 2]-cycloaddition process have been discussed earlier under dihydropyrans (p. 770) and in this section examples of its application to chroman synthesis will be covered, together with relevant ancillary material. 

The results confirmed that the ancillary materials used in an analytical procedures might contribute to blank values more than reagents themselves do, especially glassware and microwave digestion systems. Although the latter have been extensively employed to shorten the time required for sample dissolution, some problems have been ascribed to this procedure, as reported by Lima et al. [8],...

Pharmaceutical products can be contaminated by a variety of substances such as contaminants associated with microbes, previous products (both active pharmaceutical ingredients (API) and excipient residues), residues of cleaning agents, airborne materials, such as dust and particulate matter, lubricants and ancillary material, such as disinfectants, and decomposition residues from ... 

Method/Theoretical Information. Ideas, principles, theories, and techniques as well as relevant equations that apply to the project are included here. Derivations, calibrations, and other ancillary material are usually put in an appendix. Be careful not to turn this section into a list of equations. Provide enough information, both as introductory material and as transitions, to demystify the equations. In short, keep readers needs in mind as you write. 

The formulation and packaging disciplines have carried out adequate investigation or feasibility support work to establish the functional and aesthetic aspects of the pack, both primary and secondary. The primary pack (US terminology—immediate pack) may be defined as the pack which is in immediate contact with the product, and the secondary pack as the ancillary materials required for presentation, information, warehousing and distribution purposes. Feasibility or investigational work may involve information-gathering on the pack and its components, etc. (i.e. basic research into materials, packs and processes) and compatibility studies, accelerated or otherwise, on the product and pack. 

In composite artifacts, disintegration is restricted to the interface between or within discrete layers or laminants (primary stratum, secondary stratum, and ancillary material substrate) and to the contact surfaces of interlocking or frayed fabric. 

One of my jobs was to help my boss prepare for client pitches and sales calls. In the process of creating all the overheads and ancillary materials she needed, I worked with the art department. I had to figure out how to make our project their top priority when they had so many competing demands. 

The appropriate depth of the study can be checked by comparing results from a study including support processes to the main production chain, such as the production of ancillary material, with results from a study excluding them. If the difference between the two is found to be negligible, the boundary can be set to exclude these processes. The excluded processes should be indicated, however, to permit control calculations of external parties. Within the scope it is also important to include estimates on data quality and variability. 

This text comes with a variety of ancillary materials for both the student and instructor. Supporting instructor materials are available to qualified adopters.

Green chemistry and engineering principles [6,7] suggest that the use of ancillary materials not integrated in the product should be avoided, and when organic solvents and other ancillary materials must be employed, their use must be minimized and optimized to enhance reactions with minimal environmental and operational concerns. Process... 

A select group reviewed text and art manuscript in draft and final form, reviewed page proofs in first and revised rounds, and oversaw the writing and accuracy check of the instructor s solutions manuals, test bank, and other ancillary materials. 

The choice of epoxy resin, curing agent, fillers, and other ancillary materials depends on factors such as cost, processing conditions, and the environment to which the insulated electrical or electronic component will be exposed. 

Other peel ply surfaces Apart from their use for preparing bonding surfaces, peel plies are widely used as generic surface finish whenever there is no requirement for a smooth surface. During debagging, they facilitate the release of all ancillary materials that were in contact with the resin during the cure operation (e.g. breathers, bleeders, films, sealants. 

As soon as the lay-up of the component is completed, the material stack is wrapped up for cure. This operation is called bagging, or installing the vacuum set-up. The consumable materials used in this set-up are often referred to as ancillary materials, auxiliary materials or consumable materials. A typical vacuum set-up is depicted in Figs 6.9 and 6.10. Its... 

Resin viscosity The flow behaviour of the resin is determined by the permeability of the fibre reinforcement and ancillary materials on the one hand, and the resin viscosity on the other hand. The latter is temperature-dependent, and will also change over time due to the beginning polymerization reaction. As a consequence, resin bleed and. 

Debagging During cure, parts of the heated, thus liquid, resin impregnates most ancillary materials of the set-up. Once cured, this will bond the ancillary materials to each other and to the composite part. So debagging can become a delicate operation, which has to be carried out with care in order to avoid damaging the cured composite part.
