Welding consumables do not mandatorily require test certificates.  Manufacturer's certification on the packaging is acceptable as per the Code.  Consumable once certified by manufacturer for a certain classification is understandable he has made all the necessary tests including impact testing and these consumables can be used upto the lower temperature as per the mentioned classification.

If you are using the consumable at lower temperature than classified according to the consumable specification it is necessary to have a Batch test certificate from the manufacturer.  If not run a production test coupon and perform Impact test only.

Consumable should have tested for minus 52,  otherwise it may vary
