Hello, Is there a standard with HVAC that the world uses to certify a leak test for nozzles? Thank you, FGY

THANK YOU! this helps!

Hi All, I am unsure exactly what the drawing is stating here; I cannot word out what it is? i think it reads - "D.C.D" but unsure. I believe the second and third letter stands for Cold Drawing, but I've never heard of the first letter D. With MXB1113, I cannot find anything about this. is this...

Hi All, I was wondering if ASTM B633 has examples of situations or environmental affects that may relate the appropriate Type Rating & SC rating? If not, any books or key website that would best use for reference? Thank you, FGY

Hello all, It seems like there are quite the issue now and days with dichromate. Does anyone know what has replaced it in ASTM B633 standard? i do not have access to it. What has replaced it or equivalent that can pass Type VI with 120HR minimum Salt Spray pass? FGY

wow! i did not know that. The drawing called it together like this. i got so confuse. Thank you!

Hi There, May i ask if anyone know what SAE MXB1113 is? i cannot figure out what it stands for and what it is exactly? Thank you, FGY

Yes, I am testing a spec to satisfy a customer, but they have multiple parts. Trying to save cost and time. What would be the best approach to satisfied customers and my end, so both are validated, saved in cost & time?

Hello, If Multiple parts are being tested for the same finish to meet a standard, how would this task be handled? Multiple parts will not be the same, but will vary in size, design, edges, corners etc. 1. Should testing be done for all different parts for validation? 2. Should I select 1-3...

this is just a product I'm getting for HVAC. 305 can be tough to find. I would think 304 would be a good equivalent to 305?

I am specifically looking at SS 303. How well this will do in HVAC system dealing with water. I know majority of SS being used in HVAC uses 304 or 316 grade.

Hello, With Stainless Steel 300 series, are there much difference in material properties? with the increase in values (e.g. 301, 302, 303, 304, 305 etc.) what deciphers them for your needs. I do not have access to expensive websites or books. Any tips will help. Thank you

Thank you for the guidance. Respectfully, FGY

Hi All, May someone please explain this call out? i am unsure what it means. Does this mean a tangent radius of .750 is blending its way to a straight line? does it also mean the other radius below is blended with 0.750? Thank you all

as in the DC motor? if so, why aren't all the other actuators keeping the same consistent VA? nothing is different about these units

Hello All, I am outputting 108VAC, 120VAC, and 132VAC on the actuator, but the Voltage Amperage is staying consistent maybe +/-1. What would be the root cause? other actuators I'm testing has an increase VA by voltage increase. Assuming there are so many possibilities, but maybe a few big item...

I would like guidance on this material change. The new material (12L14) is the same but without Tellurium. Tellurium improves machinability and lead, but i've discovered it didn't matter for my sake. The material properties are similar, except the “Reduction in Area.” I am not too concern with...

Hi all, I am unfamiliar with this symbol (image below) being used for this drawing specifically. this is a round brass being machined down. Once machine, doesn't it remove material? doesn't the symbol represent you can do all sorts of processes, but without removing maerial? Can someone...

Hello, I am unsure, but is it a norm to put some sort of brass cutting oil + Mineral spirt on top of a finished zinc plated part to reduce rusting? is it necessary? Thank you, FY

thank you!
