FOREWORD Increased emphasis on water resources and on water conservation has had a direct effect on the petroleum industry as well as on all other industries which require large volumes of water in their operations. The petroleum industry has become extremely water conscious because in some areas...
1.1 This practice provides guidelines for biological assessment of tissue responses to nonabsorbable for medical device implants. It assesses the effects of the material that is implanted intramuscularly or intraosseously. The experimental protocol is not designed to provide a...
5.1 The chemical analysis of biological material, collected from such locations as streams, rivers, lakes, and oceans can provide information of environmental significance. The chemical analysis of biological material used in toxicity tests may be useful to better...
This specification covers polyetheretherketone
4.1 The ability of a plastic material to resist deterioration of its electrical, mechanical, and optical properties caused by exposure to light, heat, and water can be very significant for many applications. This practice is intended to induce property changes associated with end-use...
1.1 This specification covers the material requirements for calcium phosphate coatings for surgical implant applications. 1.2 In particulate and monolithic form, the calcium phosphate materials system has been well characterized regarding biological response (1, 2)2 and...
6.1 Contaminated sediments may affect natural populations of aquatic organisms adversely. Sediment-dwelling organisms may be exposed directly to contaminants by the ingestion of sediments and by the uptake of sediment-associated contaminants from interstitial and overlying water. Contaminated...
1.1 This guide pertains to corrective action monitoring before (baseline monitoring), during (remedy implementation monitoring) and after (post-remedy monitoring) sediment remedial activities. It does not address monitoring performed during remedial investigations, pre-remedial risk assessments,...
1.1 This test method is used to measure the bacterial filtration efficiency (BFE) of medical face mask materials, employing a ratio of the upstream bacterial challenge to downstream residual concentration to determine filtration efficiency of medical face mask materials. 1.2 This test...
1.1 This guide is intended to aid in the application of standards for the development, specification, and selection of chemical protective clothing with the ultimate goal of maintaining the safety and health of workers who come into contact with hazardous chemicals. 1.2 This guide provides a short...
1.1 This specification covers chemical and crystallographic requirements for hydroxylapatite intended for surgical implants. For a material to be called medical-grade hydroxylapatite, it must conform to this specification. (See Appendix X1.) 1.2 The biological response to...
1.1 This practice provides experimental protocols for biological assays of tissue reactions to absorbable biomaterials for implant applications. This practice applies only to absorbable materials with projected clinical applications in which the materials will reside in bone or...
