Checklist: Floor coverings

2. Choice of resilient coverings: Plastics, cork, linoleum and rubber
It is important you choose a resilient covering to suit the area of use and consult manufacturers for matching products. A plethora of standards exist to help you specify your resilient floor coverings, along with the "area of use class" and other properties established by BS EN 685 Resilient floor coverings – Classification. This document shows class numbers for each type of covering and their appropriate areas of use, as well as product standards for each flooring type.

Carefully consider slip resistance requirements and remember this is affected by wear, cleaning and maintenance. Slip resistance is an important quality of resilient coverings but its inclusion in standards is limited. BS EN 13553 informs that requirements for enhanced slip resistance for some plastics products are under development and will be included in standards at a later date. Agreement on a test method acceptable to EU member countries is proving difficult. The UK Slip Resistance Group has produced guidelines for the use of normal flooring materials in hazardous areas.

3. Choice of textile adhered coverings
Use carpet specification schemes to make sure the carpet meets your wear and appearance performance criteria. British Standard schemes exist for:

For pile carpets, categories L, M and N are applied according to pile thickness and mass of pile per unit area: L being assigned to thicker and heavier carpets, M to intermediate and N to lighter, thinner carpets. Level of use classes 1 to 4 are helpful in indicating where suitable textile coverings can be used. In addition, a luxury rating class from LC1 (low) to LC5 (high) is applied.

For needled coverings, the standards jointly cover all types of carpet through a common scheme establishing level of use classes.

The carpet industry widely uses the BS EN 1307 scheme for contract carpets but has concerns about its use for domestic carpet. The response was the British Carpet Manufacturers Association (BCMA) scheme, now superseded by The Carpet Foundation suitability evaluation system, known as the Quality Mark.

4. Adhesive selection
Use standards to ensure that the correct choice of adhesive for the flooring installations is made.

BS 5442-1 Classification of adhesives for use with flooring materials shows flooring types and appropriate adhesives. Although dated, it is a useful reference. Flooring and adhesive manufacturers are able to advise on current adhesive technology and provide information on appropriate products. The CFA's Guide to contract flooring also offers advice and lists the following factors as the most important affecting adhesive choice:

• Type of floor covering
  
• Backing of floor covering
  
• Type of sub-floor/underlay
  
• Temperature requirements (such as presence of underfloor heating)
  
• Horizontal or vertical bond
  
• Permanent or release bond
  
• Internal or external installation
  
• Special in service requirements (such as electrical conductivity, wet areas and so on)
  
• Health and safety considerations.
