Hi. I have been going through some product specifications and I found that in the section for microbe, some of the units declared will have either < (less than) or ≤ (less than or equal to). May I know in what situation or condition do we need to use these symbols? Is it based on the methods or a guideline that can be followed or how? Can anyone help to explain as I am not expert in microbiology?  Thank you in advance!

Hi naderk,

 

The choice in micro specs is sometimes "random" and occasionally illogical/incorrect.

 

The theoretically correct usage may depend on the specific case/numbers involved.

 

Perhaps you can give an example of your own interest for analysis/comment ?


Kind Regards,

Hi Charles C., thank you for answering but I am not sure on the case/numbers involved. 

 

In order to prepare a product specification, I have been going through some specs and saw these signs which somehow made me think in what condition should I be using the signs? As I would like to standradized the product specs that I will have to prepare. I did some readings that some said it depends on the country's regulation standard if they use less than then I should follow and vice versa.

Hi naderk,

 

Well, depending on whose Regulatory data you decide to follow will, rightly or wrongly, presumably dictate  yr specific choice ?

 

I anticipate the controlling data  in yr case will be those of Malaysian Micro. Standards although I'm unsure if such a compilation exists ?

 

If interested, you can compare presentations in Standards linked below which are of various types, eg nmMc format, maximum/minimum, etc -

One feature which should presumably exist where mixed formats occur is internal consistency, eg compare-

Attached File  micro data2.PNG   83.99KB   1 downloads

Attached File  micro data3.PNG   118.6KB   1 downloads

 

Middle one seems to have an error.

1st and 3rd are different revisions from same source and use, I daresay, equally justifiable decision criteria but give slightly different results  due the arrow-head formats. Take your pick. :smile:


Kind Regards,
