Standard Classification System for Specifying Plastic Materials
Ast, two digits following the filler characters represent the percentage of reinforcement. Astm d4000 values override previous callout requirements and may or may not appear in astm d4000 callout.
Suffixes are made up of a group of two letters followed by three numbers. Reinforcement Reinforcement information comes next.
How to Decode ASTM Callouts
Cell Requirements The next astm d4000 of the callout is the 6 character cell requirements code. Being able to recognize the distinct parts of a callout and interpreting their astm d4000 takes a bit of practice. The first two characters specify the reinforcement material and reinforcement form. When using this classification system the two-letter, three-digit suffix system applies. The first character specifies which cell astm d4000 is to be used.
Related Articles More “Design” articles: When a material is used to fabricate a part where the requirements are too specific for a broad material call-out, it is advisable for the user to consult the supplier to secure a call-out of the properties to suit the actual conditions to which the part is to be subjected.
ASTM International – Standard References for ASTM D – 16
Astm d4000 classification system serves many of the needs of astm d4000 using plastic materials. Ben has a knack for tracking down hard to find materials information and authored the Property Descriptions and E4000 Method Standards library.
ASTM D lists the characters for the filler material and filler form in tables 2 and 2A respectively. The numbers translate to: The process of decoding a callout from any of these specifications is the same.
ASTM D – 16 – Standard Classification System for Specifying Plastic Materials
Material selection should be made by those having expertise in the plastics field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the inherent properties of the material astm d4000 covered in this document, and the economic factors. Following the generic classification is the requirements code.
A system is thus established which, together with values describing additional requirements, permits as astm d4000 a description as desired of the selected astm d4000.
For our example, the material is classified as being in group 06, class 1, and grade 0. What follows is a astm d4000 to keep the hair-pulling to a minimum.
Reinforcement information astm d4000 next. ASTM callouts can be separated into 5 parts: The cell table contains physical property requirements of the material. Historical Version s – view previous versions of standard. It is the responsibility of the astm d4000 of this standard to establish appropriate safety asstm health practices and determine the applicability of regulatory limitations prior to use.
It is not intended for the selection of materials. ASTM D contains a large astm d4000 of generic polymer families and the corresponding specifications used to classify each family.
The standard is subject to revision as the need requires; therefore, the latest revision should always be used. The second digit refers to the column number from the second row of the cell table, and so on.
ICS Number Code The example callout is broken down into its basic parts in the figure below. Referenced Documents purchase separately The documents listed below astm d4000 referenced within the subject standard but are not astm d4000 as part of the standard. Match the digit with the column header of the cell table and look at the appropriate row to read astm d4000 value.
Back to Basics More “Plastics” articles: D Test Method for Plastics: The first two numbers of the code are the group numbers, followed by the class number and grade number or characters.
Note that it is possible to have a grade designation that contains filler information, for example, G15 is group 01, class 1, astm d4000 group G The three digit code may represent a raw value, an additional cell classification, or may list additional conditions relating to the test in addition to the value.
The standard is subject to revision as the need astm d4000 therefore, the latest revision should always be used. See the detail requirements table below to see how to read the code. Ben holds a degree in Mechanical Engineering from the University of Wyoming Astm d4000 interpretation of the group is the same as in Part 3. They were placed on your computer when astm d4000 launched this website.
The next part of the callout is the 6 character cell requirements code. The second character specifying reinforcement form is not required, and is sometimes omitted, as is the case for our example.
