Walk Test Requirement - Metal Flooring

Technical Questions
#1

Hi,

In ESD TR20.20-2016, section 8.3 Footwear/ Flooring System, ANSI/ESD STM97.2 can be used to evaluate systems prior to installation or with installed floors which included all floor coverings(e.g., tiles carpets, epoxies, and laminates), mats, paints/coatings, or floor finishes.

  1. Is periodic walk test required for area such as warehouse that fully uses uncoated steel plate flooring type as shown below?

  2. If walk test is required, any recommendation on how frequent it should be re-check for organization that have humidity controlled within 30% to 60% range?

Type 1
Warehouse floor type 1

Type 2
Warehouse floor type 2

Thanks.
