1.1 This specification covers floor covering having a vinyl plastic wear layer with hacking. Products may also contain non-PVC specialty performance top layer(s) or intermediate layer(s), or both.
1.2 Two types of floor covering based on hinder content are covered. The floor covering is intended for use in commercial. light commercial, and residential buildings based on serviceability characteristics. General information and performance characteristics that determine serviceability and recommended use are included in this specification.
1.3 The values stated in inch-pound units arc 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.
4.1.2 Grades—Grades shall he classified by the total wear layer thickness (sum of PVC and non-PVC wear layers). The wear layer system shall consist of a single layer or multiple layers that do not delaminate under normal use.
4.1.3 Backing Classes—Backing classes shall be arranged according to composition and use category.
4.1.3.1 Class A backings shall be fibrous (non-asbestos formulated) and suitable for floors above, on, and below-grade.
4.1.3.2 Class B backings shall be nonfoamed plastic and suitable for floors above, on. and below-grade.
4.1.3.3 Class C backings shall be foamed plastic and suitable for floors above, on, and below-grade.
5. Ordering Information
5.1 Sheet vinyl floor covering with hacking shall he ordered by type, grade. class, and other characteristics important to the purchaser for the intended use as indicated by Table 1.
6. Materials
6.1 Wear Laver.
6.1.1 The wear layer shall have a vinyl plastic hinder and may include pigments, fillers, extenders, and other ingredients, and shall be stabilized against heat and light deterioration.
6.1.2 The hinder of the wear layer shall consist of one or more vinyl resins, plasticizers, and stabilizers. Each resin shall he polyvinyl chloride or a copolymer of vinyl chloride not less than 85 % of which is vinyl chloride. The vinyl resin(s) shall he not less than 60 % by weight of the hinder.
6.1.3 The wear layer may be transparent, translucent, or opaque.
