1.1 Scope

ASME A17.8/CSA B44.8 applies to elevators permanently installed in a wind turbine tower to provide vertical transportation of authorized personnel and their tools and equipment only.

Such elevators are typically subjected to extreme temperatures, humidity variations, and substantial horizontal motions where, by reason of their limited use and the types of construction of the structures served, full compliance with ASME A17.1/CSA B44 Part 2 is not practicable or necessary.

User guide to CSA A123.26, Performance requirements for climate resilience of low slope membrane roofing systems

Scope

I.1.1 Purpose of CSA A123.26

CSA A123.26 outlines requirements for low slope membrane roofing systems (LSMRS) when identified as “silver” and “gold” performance level based on the climate severity and resilience requirements.

 

CSA A123.26-21, Performance Requirements for Climate Resilience of Low Slope Membrane Roofing Systems” was developed based on the current best practice used by the roofing community. The framework of the standard and its main sections are summarized in Figure 1.

Figure 1. The framework of CSA A123.26

Steps 1 to 3 are determined using the web-application tool “Climate-RCI” (https://nrc.canada.ca/en/research-development/products-services/software-applications/climate-rci/).

The performance requirements are provided in Table 1 of CSA A123.26.

This user guide provides guidance for the requirements as well as for the application of the requirements. This guidance corresponds to the following sections in the standard:

-      Section 5 (performance requirements)

-      Section 6 (wind performance requirements) and

-      Section 7 (rain performance requirements).

The user guide is intended to be complementary to CSA A123.26 and not a standalone document. Its objective is to simplify the process of applying the standard, minimize the possibility of misinterpretation or improper implementation of the requirements using practical illustrations.

I.1.2 Limitations of CSA A123.26 and CSA A123.27

The requirements outlined in the standard and user guide are based on best practices currently applied by the roofing community. CSA or the technical committee members shall not be liable in any event for any damages, whether direct or indirect, special or general, consequential or incidental, arising from the use of the standard and/or the guide. Responsibility lies with the professional designer.

The user guide does not address requirements specific to earthquake zones.
