ASTM F3403-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Designation: F3403 − 21 F3403 − 23
Standard Specification for
Heterogeneous Polyurethane Sheet Flooring
This standard is issued under the fixed designation F3403; 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 (´) indicates an editorial change since the last revision or reapproval.
ε NOTE—Thickness, product in Table 1 was updated editorially to match the overall thickness description in 9.1 in Febru-
ary 2022.
1. Scope
1.1 This specification covers the requirements for the compound and physical characteristics of heterogeneous polyurethane sheet
flooring that is printed or otherwise decorated to achieve a pattern or visual and protected by a clear wear layer.
1.2 This specification covers heterogeneous polyurethane sheet flooring that shall be composed of binder, fillers, and pigments.
The binder shall consist of one or more resins of polyurethane, polyurethane copolymers or other suitable or any desirable
combination. Other suitable polymeric resins may be incorporated as part of the binder, provided the polyurethane portion of the
binder is greater than 60 % in the base layer.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard 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.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

2.3 ANSI Standard:
ANSI/ASQC Z1.4 Sampling Procedures and Tables for Inspection by Attributes
3. Terminology
3.1 Definitions: For definitions of other terms used in this standard, see Terminology F141.
3.1.1 polyurethane, n—a polymer composed of organic units joined by carbamate (urethane) links. Polyurethanes can be
thermosetting (duroplastic) or thermoplastic polymers.
4. Classification
4.1 Polyurethane sheet flooring covered by this specification shall be classified as: heterogeneous polyurethane sheet flooring with
a clear wear layer. The surface structure can be either smooth or embossed.
5. Ordering Information
5.1 Purchaser shall state whether this specification is to be used, select the preferred options permitted herein, and include the
following information in the invitation bid or purchase order:
5.1.1 Title, number, and date of this specification;
5.1.2 Pattern number;
5.1.3 Quantity in square feet;
5.1.4 Size required (9.2);
5.1.5 Thickness required (9.1);
5.1.6 Lot formation if other than as specified in ANSI/ASQC Z1.4 (see Sections 11 and 13);
5.1.7 Sampling if other than as specified in ANSI/ASQC Z1.4 (see Sections 11 and 13);
5.1.8 Packing requirements if other than as specified (Section 16);
5.1.9 Palletization if required (agreement between the manufacturer and the purchaser);
5.1.10 Marking required if other than specified (Section 15) (agreement between the manufacturer and the purchaser);
5.1.11 Chemical Resistance (8.1). The basic chemicals used in the test are those likely to be found in domestic, commercial and
institutional use. Many proprietary compounds contain one or more of these basic chemicals. Should the flooring for unusual
application need to be resistant to a specific chemical, this additional requirement should become part of the procurement
document;
5.1.12 Other requirements (agreement between the manufacturer and the purchaser).
6. Materials and Manufacture
6.1 Wear Layer:
6.1.1 The flooring wear layer consists of polyurethane or other suitable combinations that minimally provide the same results as
listed in Table 1.
