Rule 1)

For ISO/IEC 17025 calibrations, when determining an “in-tolerance” or “out-of-tolerance” condition, the measurement uncertainty will not be taken into account when an “in-tolerance” or “out-of-tolerance” determination is made. Calibration for some instruments may be subject to decision-making rules that do not take into account uncertainty, unless requested by the customer.



Rule 2)

For ISO/IEC 17025 calibrations, when determining an “in-tolerance” or “out-of-tolerance” condition, the measurement uncertainty will not be taken into account when an “in-tolerance” or “out-of-tolerance” determination is made. When a measurement result for the device under test (DUT) is declared “in-tolerance”, the measured value(s) shall fall within the appropriate specification limit and the uncertainty of the measured value shall be stated and provided for customer evaluation.



Rule 3)

For ISO/IEC 17025 calibrations, when determining an “in-tolerance” or “out-of-tolerance” condition on calibrations, the measurement uncertainty shall be a consideration in that decision.

a.	If the measurement result and the associated uncertainty range are within the appropriate specification limit, the measured value will be declared “in-tolerance”.

b.	Conversely, if the measurement result and the associated uncertainty range falls outside the specification limit, the measured value will be declared “out-of-tolerance”.

c.	For a measurement result where any portion of the uncertainty range lies outside the specification limit, no “in-tolerance” or “out-of- tolerance” determination will be made. When no conformance determination is made, the measured value will be reported “as read/ indeterminate” with associated measurement uncertainty provided for customer evaluation.

d.	The device-under-test overall “as-found” and “as-left” condition will be determined on “in-tolerance” or “out-of-tolerance” determinations only.



Rule 4)

The following decision rule is used for commercial multi-brand Z540.3 (PFA=2%) calibrations and may be specified for commercial multi-brand
ISO/IEC 17025 calibrations with respect to “in-tolerance” or “out-of-tolerance” determination after guard banding criteria is applied:

a.	If the measurement result and the associated uncertainty range are within the appropriate specification and guard band limits,
the measured value will be declared “in-tolerance”.

b.	If the measurement result and associated uncertainty range intersects or exceeds an acceptance or guard band tolerance limit, the measured value will be declared “out-of-tolerance”.

What is Secure Server SSL?

A web server that has the function of encrypting information sent and received over the Internet between the user's PC and the web server is called a security server. 
If a security server is built, even if the information sent and received by the web server and the user's PC is maliciously intercepted in the middle, 
the information It is encrypted and cannot be decrypted, eliminating the riskof information leakage.

One of the ways to build a secure server is to install SSL (Secure Socket Layer) security server certificate, compared to other methods. 
so it is widely used to build secure servers.

Using this method, the web server operator can build and operate expensive security server equipment, or individual users can use separate 
Without the hassle of installing security programs, between the web server and the user's PC by installing a simple certificate on the web server 
You can encrypt the information sent and received.


Why do you need to build a secure server?

If you access a website that does not have a security server certificate installed, a security warning is displayed in the address bar of your web browser 
notifying you of the risk of personal information leakage.

Prevent information leakage
Many websites require you to enter a lot of personal information, such as your address or phone number, in order to use the service.
It is not a secure server on a public network PC such as a public institution, company, school, or Internet cafe, which has relatively weak security. 
When accessing a website on a general web server, a third party such as a hacker uses a sniffing tool to connect between the PC and the web server. 
You can easily steal the information you send and receive.

Prevent counterfeit websites A website with a security server can prove that it is an original site rather than a similar site through an SSL security server certificate. 
You can prevent phishing where third parties such as hackers create similar sites to steal personal information or financial information.

Preventing data tampering Taking advantage of security  ulnerabilities in the communication environment, maliciously altering
information between the user's web browser and the web server It can be prevented at the source.
