Methods of Analysis
Code Method

AES Arc/Spark Atomic Emission Spectrometry

T Titration

ICPA ICP Inductively Coupled Plasma Atomic Emission Spectrometry

ICPM ICP-MA Inductively Coupled Plasma Mass Spectrometry

GFAA Flameless Atomic Absorption Spectrometry using graphite furnace

C Combustion-Infrared Absorption (ASTM E 1019) traceable to CRMs

F Inert gas Fusion Method (ASTM E 1019) traceable to CRMs

CAUTION: For Arc/Spark Atomic Emission Spectrometry, an extended preburn time may be required due to the high concentration
sulfur and lead.
Co-operating Laboratories: The co-operating laboratories were:

Laboratory
Brammer Standard Co., Inc., Houston, Texas
China National Analysis Center for Iron and Steel, Beijing, China
J. Dirats and Co., Inc., Westfield, Massachusetts
LECO Corporation, St. Joseph, Michigan
VHG Laboratories, Inc., Manchester, New Hampshire

Certification Process: The requirements of ISO Guide 31, ISO Guide 34, ISO Guide 35, and ASTM Standard Guides E 1724 and
E 1831 were followed for the preparation of this reference material and certificate of analysis. This is a Certified Reference Material as
defined by ISO Guide 30.

Analysis: Chemical analyses were made on chips prepared by a lathe from the certified portion of the discs in accordance with ASTM
Standard Practice E 1806. The laboratories participating in the testing normally followed the requirements of ISO Standard 17025.
Individual values listed on page 2 are the average of each analyst's results. Methods of analysis used were a combination of ASTM
Standard Test Method E 1019 and E 415 plus additional ICP and AA spectrometric methods.

Outliers: Some outlying data was excluded from the data listed on page 2 due to technical assessment of the cooperating laboratories and
statistical evaluation.

Traceability: The following Certified Reference Materials were used to validate the analytical data listed on page 2:
SRM 10g, 15h, 20d, 129c, 2166, 3101a, 3103a, 3109a, 3112a, 3113, 3114, 3128, 3132, 3134, 3136, 3137, 3139a, 3150, 3161a, 3162a,
3163, 3165 ; ECRM 085-1 286-1.

Homogeneity: This Reference Material was tested for homogeneity using ASTM Standard M ethod E 826 and found acceptable. It was
also examined by optical emission spectrometry using ASTM Standard Test Method E 415 and found to be compatible with the
following Reference Materials: SRM 1136; CMSI 5008, 5010; SS 456/2

Validity statement: ISO Guide 31 states that the certification should contain an expiration date for all materials where instability has
been demonstrated or is considered possible, after which the certified value is no longer guaranteed by the certifying body. Whereas this
material is in a solid form and stable, no expiration date is specified.

Source: This CRM was produced by an electric arc furnace, poured into an ingot, aluminum killed, hot worked, and annealed..

Form: This CRM is in the form of a disc, approximately 41 mm in diameter and 12 mm thick.

Use: This CRM is intended for use in arc/spark atomic emission and x-ray spectrometric methods of analysis. Refer to ISO Guide 33 for
information about the use of Reference M aterials.

Certified area: The entire depth of the disc may be used.

Caution: As with any bar material, avoid arc/spark atomic emission spectrometric burns in the center of the disc (5 mm
radius), as some segregation may be present.

Sample Preparation: For best analytical results, use the same method for preparing the analytical surface on all reference materials as
you use for production specimens. Avoid overheating the disc during surface preparation.

Certificate Number: The unique identification number for this certificate of analysis is 74C-111507-px, where x indicates the page
number. Refer to future Brammer Standard Company website postings for information on any revisions to this or other Brammer
Standard reference materials..

Safety Notice: A Material Safety Data Sheet (MSDS) is not required for this material. This material will not release or otherwise result
in exposure to a hazardous chemical, under normal conditions of use. Inquiries concerning this Reference Material should be directed to:
