ASTM D4067 Call Outs

The ASTM D4067 Standard is a material callout system especially for polyphenylene sulfide (PPS) injection molding and extrusion materials. These material callouts are codes that may be used on part drawings or in other specifications to specify the use of PPS compounds having certain characteristics, without referring to any particular manufacturers or products. The ASTM D4067 material callouts listed here for our Ryton® PPS compounds represent the minimum performance characteristics of each particular product. An explanation of the meaning of these material callouts and how to determine whether a particular Ryton® PPS compound satisfies the callout given on a drawing (or other specification) is given below.

The first six characters of the material callout, "PPS000," specify that the molding or extrusion compound must be PPS-based. The seventh character specifies the types of fillers and/or reinforcements used in the compound, and the eighth and ninth characters specify the weight percent of reinforcements and/or fillers used in the compound. The tenth through fifteenth characters in the material callout specify certain minimum physical property characteristics of the compound. The significance of each character and the requirements for a Ryton® PPS compound to satisfy a callout given on a drawing (or other specification) are explained below using the example callout "PPS000G40A53343."

 

Character Significance Requirements
PPS000 The injection molding compound must be PPS-based. This is the generic PPS family designation. Currently, the callouts for all PPS compounds start with "PPS000."
G

Type of reinforcements and/or fillers:
"C" for carbon or graphite fiber
"G" for glass fiber
"L" for lubricants
"M" for mineral fillers
"R" for mixtures of fillers and reinforcements

The letter in the callout of the Ryton® PPS compound must match the letter in the callout on the drawing or specification.
40 Nominal filler content in weight percent within the following tolerance ranges:
± 2 wt. % for carbon or graphite fiber "C"
± 2 wt. % for < 15% glass fiber "G"
± 3 wt. % for > 15% glass fiber "G"
± 2 wt. % for mineral fillers "M"
± 3 wt. % for mixtures of fillers "R"
(Tolerance ranges for lubricant content must be established by agreement between the supplier and the user.)
The filler content given in the callout of the Ryton® PPS compound must be within the specified tolerance range of the filler content given in the callout on the drawing or specification.
A References Physical Properties Requirements Table A in the ASTM D4067 Standard. All ASTM D4067 callouts should have the character "A" in the tenth position.
5 Minimum Tensile Strength requirement according to performance levels defined in Table A in the ASTM D4067 Standard The number in the callout of the Ryton® PPS compound must be greater than or equal to the number given in the callout on the drawing or specification.
3 Minimum Flexural Modulus requirement according to performance levels defined in Table A in the ASTM D4067 Standard. The number in the callout of the Ryton® PPS compound must be greater than or equal to the number given in the callout on the drawing or specification.
3 Minimum Notched Izod Impact Strength requirement according to performance levels defined in Table A in the ASTM D4067 Standard. The number in the callout of the Ryton® PPS compound must be greater than or equal to the number given in the callout on the drawing or specification.
4 Minimum Flexural Strength requirement according to performance levels defined in Table A in the ASTM D4067 Standard. The number in the callout of the Ryton® PPS compound must be greater than or equal to the number given in the callout on the drawing or specification.
3 Minimum Density requirement according to performance levels defined in Table A in the ASTM D4067 Standard. The number in the callout of the Ryton® PPS compound must be greater than or equal to the number given in the callout on the drawing or specification.

 

So, for example, Ryton® R-4-230NA would satisfy the callouts "PPS000G40A53343" or "PPS000G40A43233." But Ryton® R-4-230NA would not satisfy the callouts "PPS000G45A53343" (wrong filler content) or "PPS000R60A43233" (wrong filler type and content) or "PPS000G40A63463" (may have insufficient tensile strength, izod impact strength, or flexural strength). Ryton® R-4-200NA or Ryton® R-4-200BL would satisfy the callout "PPS000G40A63463."

Occasionally, material callouts will have extensions beyond the fifteenth character or other unique notations to indicate special property requirements. Please contact our Quality Assurance representatives or Technical Service staffs regarding selection of Ryton® PPS compounds to meet these additional performance requirements.
