IPC COMMUNITY 64 SPRING 2023 "We need more toaster manufacturers," Cathy says, laughing. "An aerospace per- son can only make a decision for the toaster manufacturer because they're a user of the product." What Exactly Changed in Revision E? Teresa says A-620E was one of refinement, "cleaning up things that were hanging out there, where the industry saw differences, or things they didn't understand at first because Revision D was such a huge change." Target conditions were removed from Revi- sion D, and Revision E introduced new sections. "With Revision E, we took the time to address areas where industry said, 'Well, you took the target out, but what did that do here or there?" Teresa says. "We wanted to make some statements more understandable. Tar- get condition is like parking your car at the front spot of Walmart on a Saturday afternoon perfectly centered in the lines. "Maybe you can do it on a rare occasion, but for the most part, if you can even get in the parking lot on a day like that, you're doing good," she continues. "If you take that spot at the front door, or you aren't perfectly aligned in the blocks, now what? People say, 'What am I supposed to do here?' In fact, the acceptable may have been worded slightly different, and it left people confused." Because the document is translated into several other languages, some revisions meant looking at the wording and how it would trans- late. Much of the work done in this revision sets the committee up for a bigger revision in the next cycle. "A lot of people were wondering what the standard would become once we took out the target, but target is perfection and not obtain- able 100% of the time," Cathy says. "I feel we have a much better document without the tar- get because there are people who will rework something, trying to obtain the target condi- tion, and actually end up making things worse than what they were before. This takes away the temptation." "Additionally, some figures were adjusted so that some wording in the requirements is bet- ter understood," Teresa says. "We have a lot of international users, and they use the figures to help them understand what the words say. We had requests to make things better, to change a figure, to swap it out because it wasn't clear enough or it didn't pick up the criteria well enough." Cake and Comments Celebratory cake parties are becoming increasingly popular at IPC APEX EXPO, especially when a commit- tee has published a standard or one of its revisions. The 2023 meeting was no exception, and along with the giant sugar rush, the IPC/WHMA-A-620 committee also met to review comments that had been deferred until they could meet in person. "Now that the new revision is out, we already have requests to make changes or add content based on the changes, so we worked on some leftover stuff from the Revision D deferrals all the way through the new content," Teresa says. "It was a busy meeting."
