This specification covers the physical, chemi- cal and performance requirements of a relatively fast evapo- rating aliphatic hydrocarbon solvent typically us
2、ed for wiping and cleanup of surfaces before painting, or other operations. It is effective on hydrocarbon oils and greases and some cements and sealers. It is also used as a diluent for greases and other materials. 2 REFERENCED STANDARDS. ASTM D56 ASTM D1078 ASTM DlOl2 ASTM D1298 3 REQUIREMENTS. Ma

6、chromatographic and infrared analysis will be used to identify, characterize and qualify new materials for approval to this specification. All subsequent lots of the approved material must be compositionally identical to the initial samples submitted for qualification. 3.2.2 Purity. Minimum 99% puri
7、ty by gas chromatographic assay. The material must be free of any suspended particles, corrosion products, undissolved water, silicones or any other materials detrimental to the painting process. Product must be essentially colorless and not impart any color to coatmg materials. 3.2.3 Odor. The odor
8、 of the material shall be reviewed in comparison with current production materials. Any signifi- cant change in the material s charactenstic odor must be evaluated m a GM approved laboratory and production tnal. Any change in formulation must be reassessed for effect on odor. 3.2.4 Hazardous Materia
9、ls Documentation. The supplier must provide all required safety documentation per Section 5 upon initial submission. Toxicity and flammability will be assessed by the Hazardous Materials Committee of the using plant to determine conditions for use. The suppher must comply with all governmental regul
10、ations regarding proper labelling of hazardous materials. 3.2.5 Solvent Emissions Compliance. The supplier must furnish to the using plant s Plant Engineering Department all information required to assess the effect of material s use on meeting govemmcntal restrictions on the discharge of volatile o
11、rganic compounds (VOC) and disposal of hazardous waste. 3.3 Performance Requirements. The material must perform satisfactorily in the specified production application. Failure to do so shall constitute reason for rejection regardless of compliance with the other requirements of this specification. 4
12、 SOURCE SHIPMENT RESPONSIBILITY. It will be the responsibility of the supplier to ensure that the material is not exposed to temperatures during shipment which would cause the material to fail to meet any of the requirements of this specification. 5 INITIAL SOURCE APPROVAL. No shipment shall be made
13、 by any supplier until representative initial production samples have been approved by engineering as meeting the requirements of this specification. 5.1 Completed copies of the GM Material Safety Data Sheet and Critical Material Register (available from the laboratory or engineering department) mus
14、t be submitted with any new submissions or where a composition change has occurred. 6 INSPECTION AND REJECTION. All shipments of material or parts under contract or purchase order manufac- tured to this specification shall be equivalent in every respect to the initial samples approved by engineering
15、. There shall be no changes m either formulation or manufacturing processes permitted without prior notification and approval by engi- neering. Lack of notification by the supplier constitutes grounds for rejection of any shipment. While samples may be taken from incoming shtpments and checked for c
16、onformance to this specification, the supplier shall accept the responsibili- ty for incoming shipments meetmg this specification without dependence on purchaser s inspection. 7 APPROVED SOURCES. Engineering qualification of an approved source is required for this specification. Only sources listed
