Cetane Number

AFIDA Verification Fluid

Produced in general accordance with the principles of ISO 17034 and ISO 33405, the AFIDA Verification Fluid is a volumetric blend of n-hexadecane and 1-methylnaphthalene with a certified value, produced by accurately determining the volumes of ingredients at 20 °C. It is a highly cost effective solution to help meet verification requirements for audited laboratories and those which comply with ISO 17025.

The AFIDA Verification Material is supplied with full documentation including Safety Data Sheet (SDS), in tamper evident security packaging.

Pack size: 40 mL (set of 4).

Part Number:	SA6009-0
Methods:	ASTM D8183, EN 17155, IP 617

The AFIDA Verification Material allows routine monitoring of instrument performance and is also particularly helpful in training personnel on new equipment and test methods. The purchase of the AFIDA Verification Material is recommended with new instrumentation to assist with installation and commissioning.

Incorrect determination of a result can have far reaching financial and safety implications. The growing use of automated instrumentation increases the possibility that incorrect results may go undetected and in addition the early indication of bias is a useful warning to minimise production ‘giveaway’.

Certification: the AFIDA Verification Material is supplied with a certificate of measurement which gives the certified value for each test method covered by the material.
