Module: 060101i
Version: 8.1
Page: 2
Comment: I don't have the latest version of this module (8.3) so maybe this has already been fixed. On pages 2 and 10 it states the threshold temperature for brazing is 575C (1000F). This contradicts American Welding Society (AWS) standards which state the threshold is 450C (840F). I suggest the module be updated to match AWS.

Comment: I don't have the latest version of this module (8.3) so maybe this has already been fixed. On pages 3 and 4 it states a distinction between "copper tube" and "copper tubing" but the explanation given contradicts IPT Pipe Trades page 97, and copper.org website, and ASTM standards. At the bottom of page IPT 97, it states the trade practice used to distinguish between tube and tubing "is not an official way to designate copper tube and should be avoided". IPT explains that they are both copper tube, and they make the distinction based on the standard that the tube was made to match, specifically sizing of ID vs OD. The IPT definition also matches copper.org website definition, which references ASTM specifications for the various copper tubes. With reference and in conformance to IPT, copper.org website, and ASTM standards, I suggest the wording in the module be changed to state the copper tube types K, L, M, and DWV are designated by ID size, whereas copper tube type ACR is designated by OD size and wall thickness. Eliminate the distinction between tube and tubing, and make the distinction based on copper type and sizing.

Version: 21.0

Comment: on pg 38 second paragraph, second sentence, the information is exactly backwards. It should read: "If ambient temperatures are low when the piping is installed, you will extend the fitting somewhat; if the temperatures are high, it will need to be telescoped together somewhat." We could add; "Follow manufacturer's instructions for amount of adjustment."

Comment: on page 38, 5th paragraph, 1st sentence states that there will be a riser clamp installed on the main floor. The code states that riser clamps will be installed on every other floor, so there is not one required until the second story in a multi-story building. See Standata P-07-03-NPC15 for illustration or NPC 2015 2.3.4.4(1)

Comment: question #27 has no information in the ilm about any axial pull done or if a gasket is to be separated. this question should be removed or information added to the ilm. and question #28 references a tool not in the ilm for a process that isn't in the ilm.

Comment: need to change the PE/AL/PE content to reflect that the current name of the product by IPEX that is used for under ground water service is Q line. the brochure information can be found here http://www.ipexna.com/media/8955/brochure_caen_qline.pdf If the rest of the content of PE/AL/PE needs updating because of this then it should be done

Comment: After the first paragraph under Proxylene pipe there should be a differentiation that it is switching from talking about Proxylene to generic thermoplastic pipes and how they should be threaded

Comment: in this ILM it describes Ferrous pipe as any pipe containing iron ore and non ferrous pipe as having no iron. But in ILM 210103bA pg 41 it describes ferrous metals as having iron as its major ingredient and usually magnetic, while non ferrous may have iron but not in large enough amounts to have any major influence on its properties. one of these should be picked and the other ILM be adjusted so that there is no confusion. in one of the codes I believe its ASME where it states that it is considered to be ferrous pipe if there is an appreciable amount of iron it.

Comment: In several spots throughout the directions provided to students, the author has included menacing comments including "WORK IT OUT!" and "SIMPLE". These sorts of comments are unprofessional and a number of my students who are already struggling with basic math don't need to be additionally taunted. Please consider rephrasing.
