Re: Application for New Technology Variance - “Coated Steel Belts (CSB)” NTV-08-04
Dear Mr. Lynes:
This is to acknowledge receipt of your above referenced application dated March 28, 2008. Based on the written information previously submitted including supplemental information provided by your organization, telephone conversations with people in your organization and after consultation and review within the Department, the Department is pleased to inform you that your request for a New Technology Variance for the coated steel belt suspension means (CSB) and fabricated termination devices for the CSB suspension means has been approved contingent on the following conditions:
1. This approval is based on written information submitted for the Coated Steel Belt suspension means and fabricated terminations. Any deviation from the CSB product submitted for approval that would violate any other provision of the current or any future adopted standard would require another New Technology Variance application and approval by the Department. Changes that do not result in a violation of any current or any future adopted standard will not require another New Technology Variance application. Changes in the design of the approved CSB belt product that do not negatively impact the safety factors provided or the ultimate breaking strength or be a violation of any current or any future adopted standard will not require another New Technology Variance application, but will require notice in writing to the Department documenting said changes.
2. The requirements for which these New Technology Variances are based on the ASME A17.1b-2003 edition of the Safety Code for Elevators which is the currently adopted standard. The approvals are granted for:
a. Requirement 2.20.1 cars to be suspended by wire ropes
b. Requirement 2.20.9.3.4 un-welded cast or steel wire rope sockets
3. Until such time as the Coated Steel Belt product is fully compliant with the adopted standard in Texas, all sales contracts for equipment utilizing the CSB product will contain a clause that informs buyers that this product has been approved under the New Technology provisions of Chapter 754. As an alternative, you may provide buyers with a copy of this approval letter in lieu of a clause in the sales contract.
