Laboratory Test Request

Pyrrole Solution Flash Point and Melting Point

Project Description

Life Sciences Company needs Laboratory for flash point and melting point testing of a 100-fold dilute solution of pyrrole via ISO and ASTM Test Methods :
CFR 173.120 Class 3-Definitions.

(i) For a homogeneous, single-phase, liquid having a viscosity less than 45 S.U.S. at 38 °C (100 °F) that does not form a surface film while under test, one of the following test procedures shall be used:

(A) Standard Method of Test for Flash Point by Tag Closed Cup Tester, (ASTM D 56) (IBR; see §171.7 of this subchapter);

(B) Standard Test Methods for Flash Point of Liquids by Small Scale Closed-Cup Apparatus, (ASTM D 3278) (IBR; see §171.7 of this subchapter); or

(C) Standard Test Methods for Flash Point by Small Scale Closed Tester, (ASTM D 3828) (IBR; see §171.7 of this subchapter).

(ii) For a liquid other than one meeting all the criteria of paragraph (c)(1)(i) of this section, one of the following test procedures must be used:

(A) Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester, (ASTM D 93) (IBR; see §171.7 of this subchapter). For cutback asphalt, use Method B of ASTM D 93 or alternative tests authorized in this standard;

(B) Standard Test Methods for Flash Point of Liquids by Small Scale Closed-Cup Apparatus (ASTM D 3278) (IBR; see §171.7 of this subchapter);

(C) Determination of Flash/No Flash-Closed Cup Equilibrium Method (ISO 1516) (IBR; see §171.7 of this subchapter);

(D) Determination of Flash point-Closed Cup Equilibrium Method (ISO 1523) (IBR; see §171.7 of this subchapter);

(E) Determination of Flash Point-Pensky-Martens Closed Cup Method (ISO 2719) (IBR; see §171.7 of this subchapter);

(F) Determination of Flash Point-Rapid Equilibrium Closed Cup Method (ISO 3679) (IBR; see §171.7 of this subchapter);

(G) Determination of Flash/No Flash-Rapid Equilibrium Closed Cup Method (ISO 3680) (IBR; see §171.7 of this subchapter); or

(H) Determination of Flash Point-Abel Closed-Cup Method (ISO 13736) (IBR; see §171.7 of this subchapter).
