Plumbing Product Evaluation

Plumbing Fixtures Testing and Evaluation

Slip resistance and durability are important factors for any housing product that goes into a bathroom, around a pool, or even a kitchen. NTA can perform industry accepted tests to ensure your bathing facility product meets or exceeds requirements such as slip resistance and durability, as well as code compliance requirements as part of a certification program.

Slip resistance testing measures the coefficient of friction, which is a number that quantifies the ratio between the force needed to move one surface over another, and the difference between the two surfaces.

NTA Plumbing Certification includes (among others):

  • ASTM F462: Standard Consumer Safety Specification for Slip-Resistant Bathing Facilities
  • ASTM F1678: Standard Test Method for Using a Portable Articulated Strut Slip Tester

Another important test NTA can perform is ASTM C627: Standard Test Method for Evaluating Ceramic Floor Tile Installation Systems Using the Robinson-Type Floor Tester. This test provides important information regarding the durability of tile. Durability is an important factor in society today due to our increased focus on financial value.

What NTA can do

NTA is accredited by International Accreditation Service (IAS) under ISO/IEC 17025 to test per ASTM C627, ASTM F462 and ASTM F1678. Our accreditation is also recognized by Standards Council of Canada (SCC), which means your bathing facility product certification will not be required to be repeated for use in Canada.

While no surface is ‘slip proof’, NTA can evaluate your bathing facility products according to ASTM F462 and ASTM F1678, which contain the accepted testing methods for evaluating the slip resistance of your bathing facility surfaces.

ASTM F462 provides information to aid in determining the slip resistance of bathtubs and shower structures or combinations, used for bathing or showering. This specification establishes definitions, methods of testing the slip resistance of bathing facilities, and the in-use performance requirements needed to minimize the accidents caused by slipperiness during any reasonable use. This consumer safety specification is intended to describe a means to reduce accidents to persons, especially children and the aged, resulting from the use of bathing facilities.

ASTM F1678 covers the procedures for using a portable articulated strut slip tester (PAST) for determining the slip resistance of footwear sole, heel or related materials against planar walkway surfaces.

NTA performs testing per ASTM C627, also known as the Robinson Wheel Test. This tests the durability and strength of ceramic tile assemblies for residential and commercial construction, pursuant to the Tile Council of North America (TCNA). This test is intended for evaluating complete ceramic floor tile installation systems for failure under loads and not for evaluating particular characteristics of ceramic tile, such as abrasion resistance. This test will provide clarification on the type of traffic and wear a certain tile can expect to withstand. It can also help make comparisons between two different installation methods.
