Developmen t of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trae(TBT)Committee.

Designation:D6098-25

INTERNATIOMAL

Standard Classification System and Basis for Specification for

Extruded and Compression Molded Shapes Made from

Polycarbonate(PC)¹

This standard is issued under the fixed designation D6098;the number immediately following the designation indicates the year of

original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A

superscript epsilon(e)indicates an editorial change since the last revision or reapproval.

INTRODUCTION

This classification system is intended to be a means of calling out mechanical grade plastic product

used in the fabrication of end items or parts.

1.Scope*

1.1 This classification system covers requirements and test

methods for the material,dimensions,and workmanship,and

the properties of extruded and compression molded plate,rod,

and tubular bar manufactured from polycarbonate.This clas-

sification system allows for the use of recycled materials

provided that all specifications are met.

1.2 This standard is not intended to cover materials used in

glazing and signage as defined in 3.1.2 and 3.1.7. It is intended

to be a means of calling out mechanical grade plastic products

used for fabrication of end items or parts as defined in 3.1.3.

1.3 The properties included in this standard are those

required for the compositions covered.Other requirements

necessary to identify particular characteristics important to

specialized applications are to be described by using the callout

system given in Section 4.

1.4 The values stated in inch-pound units are to be regarded

as the standard in all property and dimensional tables.For

reference purposes,SI units are also included in Table S-PC

and Table 1 only.

1.5 The following precautionary caveat pertains only to the

test method portions,Section 12, of this standard.This stan-

dard 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.

IThis classification system is under the jurisdiction of ASTM Commitee D20 on

Plastics and is the direct responsibility of Subcommittee D20.15 on Thermoplastic

Materials.

Current edition approved March 1,2025.Published March 2025.Originally

approved in 1997.Last previous edition approved in 2016 as D6098-16,which was

withdrawn in January 2025 and reinstated in March 2025.DOI:10.1520/D6098-25.

1.6 This international standard was developed in accor-

dance with internationally recognized principles on standard-

ization established in the Decision on Principles for the

Development of International Standards,Guides and Recom-

mendations issued by the World Trade Organization Technical

Barriers to Trade(TBT)Committee.

工

3.1.1 Except for the terms defined below,the terminology

used in this classification system is in accordance with Termi-

nologies D883 and D1600.

3.1.2 glazing product,n—a finished product which is glazed

or set in frame or sash and not held by mechanical fasteners

which pass through the product.

3.1.3 mechanical grade plastic product,n—extruded or

compression molded shapes made from polycarbonate used for

fabrication of end items or parts.

3.1.4 plate,n—flat stock greater than 1/4 in.

3.1.5 recycled-plastic shape,n—a product made from up to

100%recycled plastic.

3.1.6 rod,n—an extruded solid cylindrical shape with a

minimum diameter of 1/%in.

3.1.7 signage product,n—a fabricated sign or outdoor/

indoor structure,consisting of any letter,figure,character,

mark,point,plane,marquee sign,design,poster,pictorial,

picture,stripe,line,trademark,reading matter or illuminating

device,which is constructed,attached,erected,fastened,or

manufactured in any manner so that the same shall be used for

the attraction of the public to any place,subject,person,firm,

corporation,public performance,article,machine or

merchandise,and displayed in any manner for recognized

advertising purposes.

3.1.8 tubular bar;n—an extruded annular shape with mini-

mum inside diameter of 3/s in.and minimum wall thickness of

1/16 in.

4.Classification and Material

4.1 Product shape and size as defined in the applicable

purchase order.

4.2 This classification system covers product extruded and

compression molded as listed in Table 1 S-PC.Products

included in the designations refer to specification callouts from

D3935 where applicable.

4.2.1 The polycarbonate shape product is categorized by

type,class,and grade depending on resin and filler composi-

tions as defined in Table 1 S-PC.

4.2.2 Each polycarbonate shape is categorized into one of

several grades:

4.2.2.1 Grade 1—General Purpose—Extruded or compres-

sion molded product made using only 100%virgin polycar-

bonate resin.

4.2.2.2 Grade 2—Recycled—Extruded or compression

molded product made using any amount up to 100 %recycled

polycarbonate plastics.

4.3 The type,class and grade is further differentiated based

on dimensional stability (elevated temperature excursion test),

Table 1 S-PC,and dimensional requirements, Table 2 A-1,

Table 3 B-1,and Table 4 B-2.

4.4 Property Tables:

4.4.1 Table 1 S-PC is used to describe both extruded and

compression molded products.

4.4.2 Table 5 is used to describe extruded or compression

molded products not included in Table 1 S-PC via a cell callout

that includes the applicable Table 1 S-PC polycarbonate type

and specific properties(Designations 1-7).

4.4.3 To facilitate the incorporation of future or special

materials not covered by Table 1 S-PC,the “as specified”

category(00)for type,class and grade is shown in the table

with the basic properties to be obtained from Table 5,as they

apply.

4.4.4 Reinforcements and Additive Materials—A symbol

(single-letter)is used for the major reinforcement or

combination,or both,along with two numbers that indicate the

percentage of reinforcement and/or additive by mass with the
