demand/demands? on/of?

[mccalle]

Hi,

I have some troubles with a sentence which says "The specification consists of technical criteria that the package must fulfil in order to meet the quality demand of a selling product."

Shall it be "demand" or "demands"?
Shall it be "demand of" or "demand on" in this case?

Thanx

I'd choose "... the quality demands of a selling product"
There is likely to be more than one 'quality demand'.
You could think of the demands as being on the product. But saleability demands a certain quality of the product. In any case, you can't demand quality 'on' something, only 'of' it.

I am not a teacher, but in this case the correct word is demands.

If you are using demand to a mean a certain requirement or command, you would use demands:

"This automobile must meet the demands of many different customers."

If you are using demand to mean the desire of purchasers for a product, you would use demand:

"We must start producing more automobiles to meet the increased demand from our customers."

Thank you for your help. I used "demands" and "quality of" of course
I think I should use "should" more than "shall"
