Uncertainty

The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034 with an 95% confidence level(k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation, homogeneity and stability testing. Stability values are based on real evidence opposed to simulation.

Traceability

The balances used for gravimetric measurements are calibrated with weights traceable to the national standards. The calibration of the balances is verified annually by an external accredited calibration service. This analysis method has been verified using an approach consistent with ISO 17034:2016 & ISO 17025:2017.

Intended Use

This RM is intended for use in a laboratory as a calibration and quality control standard or in method development for analytical techniques.

Storage

This reference material meets the specification stated in this certificate until the expiry date, provided it is stored unopened at the recommended temperature here in. If storage after opening is necessary, the RM should be tightly closed and kept from light and moisture.

Hazards

Read Material Safety Data Sheet (MSDS) and understand any potential hazard(s) prior to the use of this product. All chemicals should be considered potentially hazardous in nature and should only be handled by qualified personnel using established good laboratory practices.

Homogeneity

Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO 17034.

Instructions for use

It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase the certified uncertainty by a factor of two for half sample and four for a quarter of sample.Visit the support section of our website technology videos and frequently asked questions.

Section III. Hazards Identification
Harmful if ingested or inhaled. Minimize exposure to this material. Severe overexposure can result in injury or death.
Acute Health Effects
Irritating to eyes and skin on contact. Inhalation causes irritation of the lungs and respiratory system. Inflammation of the
eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or,
occasionally, blistering.
Skin contact may result in sensitization. Always cover all exposed skin with an impermeable layer and use proper eye
protection. A OSHA/MSHA approved dust and vapor respirator is required when working with this material.
Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
Chronic Health EffectsCARCINOGENIC EFFECTS : Not available.

TERATOGENIC EFFECTS : Not available.
DEVELOPMENTAL TOXICITY: Not available.
Repeated or prolonged exposure to this compound is not known to aggravate existing medical conditions.

Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical attention.
Skin ContactIn case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing
before reuse. Thoroughly clean shoes before reuse. Get medical attention.
If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
Inhalation
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
Ingestion
Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic
material was ingested; the absence of such signs, however, is not conclusive.
