1.1 This classification system covers requirements for cellulose acetate thermoplastic compounds plasticized with either diethyl phthalate or dimethyl phthalate and are suitable for injection molding and extrusion. These compounds have an acetyl content between 39 and 40 %. It does not include materials compounded for special application. Cellulosic plastic materials, being thermoplastic, are reprocessable and recyclable. This classification system allows for the use of those cellulosic materials, provided that all specific requirements of this classification system are met.1.2 The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are specified by using the suffixes as given in Section 5.1.3 This classification system and subsequent line call out (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastic field only after careful consideration of the design and performance required of the part, environment to which it will be exposed, fabrication process to be employed, costs involved, and inherent properties of the material other than those covered by this classification system.1.4 The values stated in SI units are to be regarded as standard.1.5 The following safety hazards caveat pertains only to the test method portion, Section 11, of this classification system. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: There is no known ISO equivalent to this standard.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This guide is intended to provide a rapid, easy to use method for identifying Committee F16 fastener specifications and their applicable marking requirements. Selection is made by product type (bolts, nuts, washers, etc.) and material (alloy steel, carbon steel, stainless steel, etc.). Table size limitations and the need for simplicity prohibit identifying the exact grade, type, condition, etc., for all product/material combinations. The product specification must be reviewed prior to specifying fasteners on drawings or ordering to properly and completely identify the fastener, and its available variations.1.1 This guide is intended to provide a rapid, easy to use method for identifying Committee F16 fastener specifications and their applicable marking requirements.

5.1 These specifications are designed to ensure that evidence associated with a sexual violence investigation is handled and analyzed in the most useful manner and without wasting evidentiary materials and analytical time or resources, or both.AbstractThese specifications describe the basic elements of a request for the scientific examination of physical evidence collected in the investigation of a sexual assault. These specifications outline considerations that will facilitate the analysis of sexual assault evidence by a potentially large group of forensic experts. The request for scientific examination of sexual assault evidence should include a completed sexual assault medical/nurse sexual assault examiner/medical examiner evaluation form in accordance with the requirements.1.1 These specifications describe the basic elements of a request for the scientific examination of physical evidence collected in the investigation of a sexual violence incident. These specifications are designed to be used in conjunction with other specifications, guides, and practices associated with sexual violence examinations that are listed in Section 2.1.2 These specifications outline considerations that facilitate the analysis of sexual violence evidence by forensic experts. These experts can include, but are not limited to, serologists, toxicologists, pathologists, odontologists, latent print examiners, firearm and toolmark examiners, and trace materials analysts. The success of their combined work requires a clear understanding of the issues and relationships involved in the case.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
