Comment: In the Specifications section of Example Two on page 27, ILM states Bolt hole diameter = 20 mm. But IPT Pipe Trades page 229, shows it should be 22 mm. If accepted, this comment will also affect the corresponding One half scale value, changing from 6.67 mm to 7.3 mm.

Comment: On page 14 just above the Caution box. Before they put the new images in the ILM's there used to be 3 bullets, followed by a blank line, and then the sentence: "If the crane is to lift the load without tipping, the crane leverage must be greater than the load leverage." In this new version, the bullets are gone, but the text of the bullets is there. And following the text of the 3rd bullet, there is no space between it and the next sentence, creating a confusing run-on sentence. Have a look at previous versions for comparison.

Comment: In the second paragraph, the first sentence says "...(1//2" to 144" national pipe size [NPS] ..." That should say nominal instead of national. Also, same paragraph, second sentence, it says " ... 150 pounds per square inch general (psig) ..." That should say gauge instead of general.

Comment: Throughout ILM 070204c there is a mixture of spellings of gray cast iron (sometimes grey with an 'e'). For consistency's sake, I suggest that all instances be spelled with 'a' as this is how it is spelled in IPT Pipe Trades.

Comment: Starting on page 7, and carrying on to various parts of the ILM, there is a variety of numbering systems used to identify alloys. For example, on page 7, stainless steels are listed as 200, 300, and 400 series. I think these are AISI or SAE or ASTM code numbers. Then on page 9 in the Aluminum Alloy section, it references the 3003, 6061, and 6063 aluminum code numbers. Then it goes on to state the first number of those codes is the most important and lists some examples but does not state which code is used. I think it is the Aluminum Association (AA) codes. I think some text should be added to the ILM to describe the various numbering systems and the corresponding codes, and the gradual move to the Unified Numbering System (UNS). In an older version of this ILM (070204c version 5.0), there were pages 21-22, that described the problem of having the various codes (AISI, SAE, ASTM, AA, etc.) and how the UNS aims to solve this. It would be nice to have that text, and an even more in-depth explanation, back in this ILM v.24.

Comment: Near the top of page 8, the acronym AISI is used for the first time in this ILM, but is not defined. I suggest that it be defined (American Iron and Steel Institute), as it is good practice to define acronyms the first time they are used. You may also consider adding a link to the AISI website: steel.org

Comment: On page 19, the text for the bullet "Potential (emf) Difference" says: 'the metal higher in the series will corrode and protect the one lower in the series.' In a much older version of this topic there used to be a chart/table with various noble metals listed, and the less noble metals were at the top, and the more noble metals at the bottom. So the statement 'the metal higher in the series' when compared to the chart, made sense, as it referred to the less noble metal at the TOP of the chart. But without the chart, the definition now in the ILM is somewhat confusing. On the previous page 18, it now states 'ions of material are removed from the lower (less noble)' and this is correct as I understand electrolysis. My suggestion is to edit page 19 and change 'metal higher in the series' to say 'lower less noble metal in the series.' And also change on page 19 'the one lower in the series' to be 'the higher more noble metal in the series.' These edits will make it be consistent with the text on page 18. Also, *if* you do want to put the chart/table back in (and I don't necessarily think it should be, but would be nice), then please have the chart put the more noble metals at the top and the less noble metals at the bottom (the reverse of the old chart; there are good examples all over the internet.)

Comment: On page 2 070204e version 24, the last paragraph states RTG (ring type gasket) is shown in Figure 1. This looks the same if not exactly like 1st year Figure 24, page 26, from ILM 210102c version 24. Except in 1st year it is RTJ ring type joint (not gasket). Also, IPT Pipe Trades, starting on page 223 and continuing throughout the Flange section, uses the term Ring Joint to describe this flange. Shouldn't this 070204e ILM be consistent in naming by using RTJ instead of RTG?

Comment: On page 3 of 070204e version 24, there are 3 joining methods mentioned. These 3 appear to be for thermoplastic material, but that is not mentioned anywhere. It is of particular concern for the 1st method, Fusion Welding, since this method could apply to metals and other types of materials.

Comment: Figures 24-27 all show dimension G at the top right of the image, but it should be dimension F. This dimension should be F because as you progress through the text and images of the example described in the text, when you get to Figure 27, the correct dimension G is shown near the centre of the image, resulting in a duplicate G at the top right. If you change the image as suggested above, you will also need to edit/change the text on page 20, paragraph 3, last sentence. Change to reference F instead of G. Also on page 20, the first sentence should reference Figure 26, not Figure 19.

Comment: On page 22, in the Specifications section of Example One, it states the Actual ID for the gasket as 50 mm. According to IPT Pipe Trades page 224, quote: The I.D. of gasket should equal the outside diameter of the pipe for full and raised face. end quote. It appears the author has used the NPS as the ID of the gasket, but according to IPT the ID of gasket should be OD of pipe (not NPS). In this Example One, it should be 60.3 mm (according to IPT page 33.) If you accept this comment, then also change the Specifications in Example Two on page 27, Actual ID should be 168.3 mm.

Comment: Objective Three: Define Coordinate Systems. ILM pages 17-18 are the only pages in this ILM for this objective, and they only describe one of the two main coordinate systems. The two systems are: grid line coordinates (as seen in objective three), and compass coordinates. Compass coordinates use compass directions, such as northings and eastings, or northings and westings. There is a brief mention of northings and westings on page 3 of this ILM, but I think it should be described in detail in objective three, along with related activities.

Comment: Page 41, Objective Six Activity, Question 1. I calculate the answer to be 115 ft3/hr, which is none of the choices. The answer on page 56, says a) 100 ft3/hr, and on page 41, 100 ft3/hr is b). My calculation: using Table 2, at 36 seconds, the 1 ft3/hr dial shows 100 ft3/hr. But the question says the pressure correction factor (pcf) is 1.15. So multiply 100 ft3/hr times 1.15 (pcf) to get 115 ft3/hr. The remaining questions in the Activity have correct answers, using the provided pcf.
