ASTM D7888-18

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: D7888 − 13 D7888 − 18
Standard Practice for
Evaluating Adhesive and the Effects of Plasticizer Found
1
Within Polyvinyl Chloride-Backed Floor Coverings
This standard is issued under the fixed designation D7888; 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.
1. Scope
1.1 This standard will provide a qualitative means to determine the potential effects of plasticizers contained within polyvinyl
chloride (PVC) floor covering materials on a specific adhesive.
1.2 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.
1.3 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.4 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.

3. Terminology
3.1 Definitions:
3.1.1 plasticizer, n—additives that increase the plasticity or fluidity of a material; a chemical added especially to rubbers and
resins to impart flexibility, workability, or elasticity.
3.1.2 polyvinyl chloride (PVC), n—a thermoplastic polymer used in many floor covering materials.
4. Significance and Use
4.1 Plasticizer migration is detrimental to many adhesives, including hot melts, which could be possibly used in conjunction
with PVC backed flooring materials, whether resilient or textile, broadloom, tile or plank. This practice can be used as an indicator
to determine if plasticizers in the flooring material are compatible with proposed installation adhesive(s).
5. Apparatus
5.1 Circulating Air Oven, capable of maintaining 140 6 3°F (60 6 2°C).
5.2 Test Adhesive.
5.3 Test Floor Covering.
5.4 Floor Covering Seam-roller, (approximately 2 lb (1 kg).

5.6 Four Pieces of Aluminum Foil, approximately 26 in. by 10 in. (66 cm by 25 cm).
6. Procedure
6.1 Cut four 6 in. by 6 in. (15 cm by 15 cm) pieces of the PVC backed flooring test material. Material composition can be textile
or resilient.
6.2 Using the recommended application method as instructed by the floor covering or adhesive manufacturer (trowel, roller, or
spray) apply the adhesive to the backing of two of the 6 in. by 6 in. (15 cm by 15 cm) pieces of floor covering. If no application

method is specified use a ⁄32 in. by ⁄16 in. by ⁄32 in. (0.079 cm by 0.16 cm by 0.079 cm) U notched flooring trowel.
6.3 Allow the adhesive on the test specimens to dry at room conditions maintained at 73 6 3°F (23 6 2°C) and 50 6 5 %
relative humidity for not less than 3 h before testing.
