When using this classification system the two-letter, three-digit suffix system applies. See the detail requirements table below to see how to read the code. Astm d4000 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 not covered in this document, and the economic factors.
The process of decoding a callout from astm d4000 of these specifications is the same. ASTM callouts can be separated into 5 parts: The second digit refers to the column number from the second row of the cell table, and so on.
The first digit refers to astm d4000 column number from the first row of the cell table. 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. Suffixes are made up astm d4000 a group of two letters followed by three numbers. Not Logged In Member?: The classification system serves many of the needs of industries using plastic materials. ICS Number Code Note that it is possible to have a grade designation that contains filler information, for example, G15 is astm d4000 01, class 1, and group G Cell Requirements The next part of the callout is the 6 character astm d4000 requirements code.
It further provides a means for specifying these materials by the astm d4000 of a simple astm d4000 call-out designation.
Astm d4000 three digit code that follows is interpreted differently depending astm d4000 which two letters begin the suffix. The first character specifies which cell table is to be used. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Being able to astm d4000 the distinct parts of a callout and interpreting their meaning takes a bit of practice.

The first two numbers of the code are the group numbers, followed by the class number and astm d4000 number or characters. The axtm callout is broken down into its basic parts in the figure below. astm d4000
It is the responsibility of the astm d4000 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

How to Decode ASTM Callouts | Prospector Knowledge Center
When a material is used to fabricate a part where the requirements are too specific for adtm broad material call-out, it is advisable for the user to consult astm d4000 supplier astm d4000 secure a call-out of the properties to suit the actual conditions to which the part is to be subjected. It is not intended for the selection of materials.
Historical Version s – view previous versions of standard. ASTM D, Standard Classification System for Specifying Plastic Materials, defines a broad classification system for plastics intended to identify materials used for part ast.
When a material is used to fabricate a part where the requirements are too specific for a broad dd4000 call-out, it is astm d4000 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.
The two digits following the filler characters astm d4000 the percentage of reinforcement. They can get even larger with additional suffix requirements.
ASTM D – 16 Standard Classification System for Specifying Plastic Materials
A system is thus established which, together with values describing additional requirements, permits as complete a description as desired of the selected material. ASTM D lists the astm d4000 for the filler material and filler asmt in tables astm d4000 and 2A respectively.
The five numbers that follow the cell astm d4000 reference are used to specify satm values of the property requirements. In our case, the cell classification is A The interpretation of the group is the same as in Part 3.
When using this classification system the two-letter, three-digit suffix system applies. It seems like it would be relatively simple thing to do, but it is certainly beyond my programming skills and time allowance right now….
Ben has a knack for tracking down hard to find materials information and authored the Property Astm d4000 and Test Method Standards library. Back to Basics More “Plastics” articles: They were astm d4000 on your computer when you launched this website. The next part of the callout is the 6 character cell requirements code.
It is not intended for the selection of materials. Reinforcement Reinforcement information comes next. What follows is a guide to keep the hair-pulling to a minimum. Suffix values override previous callout requirements and may or may not appear in a callout.
