The user is responsible to consult appropriate safety and health practices and to determine the applicabi
4、lity of regulatory limits prior to use. Change Notice: Added RA for Izod impact, corrected technical information in Section 12, editorial changes. 1.0 SCOPE This specification provides a system for describing and specifying the significant requirements of a plastic part. The system includes the spec
5、ification of both basic resin properties and specific performance requirements of the finished molded part. 2.0 INTRODUCTION This specification is not applicable to fiberglass reinforced thermosetting polyesters such as SMC. Fiberglass reinforced polyester parts are covered in CEMS D-22. The specifi
6、cation is based upon the principle that requirements for plastic parts are best described in terms of the performance characteristics desired in the finished molded part. However, it is recognized that specification of some basic resin properties is often required and/or is helpful as guidance in se
7、lecting a material that will be capable of meeting the part performance requirements. 2.1 Restricted Chemical Substances Effective January 1, 2007, all product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification. 2.2 Specifying on Draw
8、ings While this line call-out system provides the means for close characterization and specification of each property and combination of properties in a broad range of plastic parts, it is subject to possible misapplications since property combinations impossible to achieve with currently available
9、commercial materials and processing techniques can be coded. Materials Engineering should be consulted before specifying line call-outs on engineering drawings and blueprints. 3.0 CONTENTS PAGE INTRODUCTION 1 REFERENCE DOCUMENTS 2 GENERAL REQUIREMENTS 2 PART MARKING REQUIREMENTS 18 QUALITY 18 SOURCE

14、TION OR GRADE DESIGNATION Plastic parts are classified by material type and properties. 6.0 GENERAL REQUIREMENTS 6.1 General Resin Characteristics The general type of plastic resin used to manufacture the part will be identified by an alphabetical symbol in the line call-out. The symbol used for bas
15、e resins will be as defined in Table 1. Symbols used for polymer blends (alloys) will be as defined in Table 2. 6.1.1 POM in the above example is a standard symbol for the polyoxymethylene family of plastics with common trade names such as ACETAL, Celcon, and Delrin. 6.1.2 ABS+PC in the above exampl
16、e is a standard symbol for the acrylonitrile / butadiene / styrene + polycarbonate family of plastic alloys with common trade names such as Bayblend, Cycoloy EHA, Proloy, and Pulse. 6.2 General Part Requirements Parts will be uniform in density, color, texture, finish, electrical, and mechanical pro
17、perties; and free of porosity, warpage, checks or cracks, chipped edges, blisters, and uneven surfaces. Unless more specifically defined on engineering drawings, appearance and finish of parts will conform to good commercial practice (free of gates, flash, ridges, roughness, and tool marks; and of m
18、old lubricants and other contamination). 6.3 Additional Part/Resin Characteristics/Properties (Requirements) General characteristics of resins and parts are described by alpha-suffix symbols as shown in Table 3. Characteristics shown in Table 3, which are applicable to both resin and molded part des
19、ignations, are indicated with an asterisk (*). More specific properties of resins and/or parts are described by an expanded line call-out specification consisting of alpha-numeric suffix symbols as described in Table 4. 6.3.1 Example 1 ASA, A3A46A64DF1060K40M16R2200S75YB2400AC1AE6, MPAPS D-28 6.3.1.
