HIC test and SSC test on a valve

[ElenaN]

Hi,
Im new in this industry and I work for quality assurance job in our company.
Our company makes carbon, stainless and high alloy castings for industrial valves, pumps and other flanges.
Currently, our customer required a valve made A216 WCB and also HIC, SSC test on that valve.
As I know, HIC does not occur in castings, rehardless of the material.

Is that necessary for the valve?
or is this not matter because the test will be works on specimen of the product not product itself?
On the NACE there is no specification about this directily.
What is HIC test? How does the HIC test works on the product exactly?
If the customer wants..do we have to do this test on our porduct regardless of spcecifications like NACE or others?

Im sorry about my english skills. I think maybe you cannot understand my words accurately.
But If you answer my questions, I will thank you.

On test requirements:

1. If any customer include tests in his order, make sure that he also gives exact information. In this case: full reference to the (valid) standard, and exact test description and the result he requires and will accept.

Most customers know exactly what they are doing when describing, but also often uses 'local technical slang' in stead of full proper description.

2. NACE tests may be required for instance for North-Sea valves for offshore use.
